As far as Yuuto Kiba was concerned, his life couldn't get any weirder than it already was. However, each time he tried to reaffirm his belief, he would be proven wrong. As a former human who was resurrected into a Devil after dying, and serving under a Duke of Hell, he should have started to change his way of thinking.

The Knight let out a sigh. While he was mostly alright with the current events, like being promoted into a Middle-Class Devil and some other things, he needed to keep his guard up or else he might get himself taken off-guard by some unexpected events that might come in the future.

"Oh well…" Kiba shrugged as he continued walking down the street on his way home from grocery shopping. He had been living next door to Hyoudou's household for quite some time, and on his way home, he could see the large house next to his. Due to its size, it was kind of hard to miss. "I shouldn't stress myself by thinking about such things for now."

Unlike before, Kiba had grown stronger. While he believed that he still needed some catching up to do before he could call himself Issei Hyoudou's equal, he thought that he could at least face the future obstacles without having as much trouble as before.

His lips curled up into a small smile as he recalled his fellow Devil, who was initially the weakest member in the peerage. Due to a combination of determination, hard work, luck and sheer stubbornness, Issei Hyoudou had become a person who should not be trifled with. As a teammate and a friend, Kiba couldn't help but to feel proud.

On his way home, he saw two people walking down the street from the other direction. When he took a good look on them, he recognized both of them as Asia Argento, an ex-nun and another fellow Devil, and Issei Hyoudou. Asia seemed to be carrying something in her arms while Issei was walking alongside her.

"Hey, it's Kiba!" Issei noticed the blond devil's presence before he jogged towards him. "What's up?" The perverted boy grinned at him, a grin that Kiba happily returned.

"Just returning from a little shopping," Kiba said, showing both Asia and Issei the grocery bag in his hand. "How about you two?" He asked before he looked at the object that Asia was holding. He raised one eyebrow as he saw that the ex-nun was holding some kind of mirror with both hands. From what he could see, it was quite an antique mirror. "What is that?" He gave Asia a questioning look.

"Oh, are you wondering about this mirror, Kiba-san?" Asia asked as she looked at Kiba, holding out the mirror.

"Yeah," Kiba nodded. "It's definitely an old mirror, no matter how I look at it," Kiba said, once again proving his capacity in pointing out the obvious.

"W-well, you see…" Issei started, rubbing the back of his head sheepishly. "When we were in the Underworld a few days ago, I somehow bought this mirror at an antique shop." He grinned despite the sheepish look on his face. "The shopkeeper told me that I can use this mirror to peep on girls." There was a perverted look on Issei's face as he made groping motions with his hands.

"But then you found out that the mirror couldn't do such a thing, right?" Kiba said, sighing. No matter how much he looked at it, it was clear as day that Issei Hyoudou, one of the most famous figures in the Underworld with titles like the 'Crimson Dragon Emperor' and the 'Oppai Dragon Emperor', had been scammed by a shady salesman in the Underworld. "It's just a normal mirror, isn't it?"

Issei seemed crestfallen. "Yeah…" he said, sulking. "Not only that, but I wasted near three thousand yen to buy this junk." He shrugged. "Oh well, I guess we can bring this to our clubhouse and put it there."

Asia nodded. "Yeah! This is an antique mirror, so we thought we can use this for our club's décor." A smile was seen on the ex-nun's face. Despite Issei's careless actions in buying the mirror due to his perverted thoughts, Asia didn't seem to mind it much. "What do you think, Kiba-san? Do you think it's good to put this mirror in the clubhouse?"

Kiba stared at the mirror in Asia's hands. He could see his own reflection in the mirror. "Well, I guess it matches the antique look of our clubhouse. Yeah, it's a good idea." He nodded, agreeing with Asia's decision.

Asia beamed cheerfully. "That's good! Alright then, we'll be heading to the school now so we can put this mirror in the clubhouse. Let's go now!" She said to Issei.

"Alright, let's go, Asia-chan!" Issei said, nodding as well.

Kiba smiled. Well, it was good to see them doing something like this once in a while.

Asia and Issei were about to leave, but suddenly the ex-nun stumbled. "Eh?" And then fell to the ground. "Eeek!"

"Asia-chan!"

Crash!

"Kyaah!"

Alarmed by the breaking sound and Asia's scream, Kiba, who was about to walk home, immediately shifted his attention to Asia, and saw the ex-nun on the ground, slumped on her side. Issei was crouching by her side, panicking.

"Asia-san!" Immediately, Kiba rushed to Asia's side. "Are you alright?"

Grimacing, Asia looked at Kiba before she forced herself to smile. "I-I'm unhurt. B-but…" she looked at the shards of the mirror she held before she fell, and her smile faltered. "T-the mirror!"

The mirror was broken and in pieces. Its broken shards were on the ground.

"It broke…" Issei said.

"Yeah, it broke…" Kiba agreed, nodding.

"Hawawawa!" Panicking, tears started to gather in Asia's eyes. "I-I'm sorry! I-I didn't mean to break the mirror! I'm sorry!"

Kiba and Issei sighed in unison. Then Issei patted Asia's head. "As long as you're unhurt, it's alright. It's just a mirror…" he said, trying his best to reassure the panicking ex-nun.

"B-but… it's expensive!" Asia protested.

"Well, like Issei said, as long as you're not injured, it's not really a big deal…" Kiba said, crouching so that he could pick up the broken shards of the mirror. "We should clean this up, or else other people may get injured if we leave them here." He picked one of the shards, examining it. While it might be a waste, there was nothing they could do about it.

Issei nodded upon hearing Kiba's suggestion. "Yeah. We should-"

Before the perverted boy could finish, suddenly the broken shards of the mirror glowed. The one who was picking one of the shards, Kiba, blinked in confusion.

"Eh?"

Before the Knight could even do anything, his entire body was enveloped in bright light as a feeling of vertigo washed over him.

"Kiba!"

"Kiba-san!"

He could hear both Issei and Asia shouting his name before he was blinded by the brilliant light that enveloped him. The vertigo he experienced along with the light brought a feeling of weightlessness in him.

Then, he felt like he was falling.

Fang Knight of the Three Kingdoms

High School DxD and Koihime Musou Crossover

Chapter 01: Devil Meets Girl

When Kiba came back to his senses, he realized that he was really falling. The cold air and the clouds around him made him assume that he was falling from the sky. Having no luxury to think about it excessively, he immediately tried to put his focus on landing safely as a pair of bat-like, leathery pinions exploded out of his back. They expanded to their full length so that they could support his weight as he continued falling.

Yuuto Kiba is a Devil, and the bat-like wings on his back were the proof. Originally a human, albeit an enhanced one, he was resurrected as a Devil by Rias Gremory after dying. Being a creature of darkness that is prominently mentioned in the bible, Kiba is a part of a race that once waged a great war against the two other biblical races or factions, Angels and Fallen Angels. All the three races had been antagonistic against one another even after the end of the war, but the antagonism was finally put to an end when an alliance was made in order to fight a greater threat in the form of Khaos Brigade.

Using his Devil wings, Kiba was able to steer his way as he fell, but he was unable to completely stop himself from falling. If he tried to use his wings to stop his fall, then he might end up breaking his wings. Having no choice, he used the wings to glide through the air as he fell. He gritted his teeth and brought his arms to his face, protecting it from the cold air.

He flapped his wings as he steered his way downward, hoping that his landing could be softened by something at the ground below. But with the cold air hitting his face, it was hard for him to see.

Kiba could feel that he was about to hit the ground. Bracing himself, he prepared himself to make sure that he could land safely.

"Hmpf!"

"Kyaa!"

As Kiba's mind was preoccupied with his landing strategy, he did not expect to land on someone before having his face stuffed between two breasts. His mind went blank as his face was stuffed between a pair of mountainous assets, knocking the person he landed on a few meters away before crashing onto the ground.

He managed to land, all things considered, but it was more like a crash landing than anything.

A few minutes before the crash landing of one named Yuuto Kiba, there was something happening on the ground.

There was a group of thuggish, unscrupulous-looking men of varying degrees of ugliness, armed with weapons as they stood before a young woman armed with a glaive or rather, a guandao. The men leered and sneered at the young woman, further contorting their features. The glaive-wielding young woman gritted her teeth, brandishing her glaive as she glared at the men before her.

The young woman, whose long, shiny black hair was tied up into a side ponytail, tightened her grip on her weapon. The handle of the guandao was red in color, and had a blade with crimson linings. She was attired in a white-and-green, gold-trimmed dress with detached sleeves, exposing her shoulders. Her rather short black skirt also exposed her shapely legs that were covered by a pair of dark-colored thigh-high stockings. The expression on the young woman's face was grim as she looked at the men standing before her with a piercing glare. Behind her were an old man and a young girl, cowering in fear as they huddled together, trembling. From the look of it, the young girl might probably be the old man's daughter or granddaughter. A dead mule and a broken cart were seen not too far from them.

"Stand down, you pigs!" The young woman bellowed at the men. Despite the anger in her voice, one could also feel the confidence in her tone and stance. She looked like she was telling the men to stand down so that she wouldn't have to fight them.

"Well, well… look what we got here…" one of the men, a lanky, gaunt-looking one with tanned skin, clad in sleeveless shirt and light armor, spoke, grinning as he rested his sword over his shoulder. There were three of them. One of them was a midget-looking man with imp-like appearance and the other one was a fat man with imposing look.

"Kehehehehe…" the midget-looking man cackled, looking at the young woman before them lustfully. He was also holding a sword in one hand, an imp-like grin spread over his ugly face. "We dunno who you are, but we might as well beat ya, strip ya and rape ya senseless before we sell ya as a slave."

The young woman made a disgusted face. Her amber eyes were glinting under the sunlight as she glared at the men.

"How repulsive…" the young woman spat. "How dare you threaten to lay your dirty hands on these people?!" She pointed her spear at the men. "Know your place, foul bandits!" She was protecting both the old man and the young girl from these men, the bandits.

The lanky bandit sneered. "Heh… what a brave woman…"

"If you are willing to flee now, I shall allow you to escape." The young woman spoke, her tone sounded significantly softer than before. But then, her expression hardened as she brandished the spear in her hands. "However, if you insist to fight…" the blade of her guandao glinted under the sunlight, and the young woman allowed herself to smirk. "Then be prepared, as you shall face my Green Dragon Crescent Blade!"

"Heh…" the lanky bandit jeered. "You talk big, for a woman! Hey, midget!" He shouted at the midget-looking bandit beside him.

"Yes sir!" The imp-like bandit saluted before he shouted at the fat one. "Hey, Fatso!"

"O-okay, I'll get her…" the fat bandit mumbled a reply before he brandished a spiked mace with both hands. Despite its size and weight, the fat bandit was able to lift it with only one hand effortlessly. One could tell that even with one swing, he would be able to crush someone's head with it.

"Ho? A fight it is, then?" The young woman noted as the fat bandit walked slowly towards her, his mace readied in his hand. "Very well!"

Then, the fat bandit lumbered towards her, swinging down his mace onto her. Unperturbed, the young woman shifted her grip on her glaive before she blocked the attack using its handle The sheer weight and pressure from the attack caused her knee to buckle slightly, but her face didn't show any sign of being pressured by the attack. She shifted her weight, changing her position before she used the handle of her weapon to attack the bandit's head, slamming it.

"Grkh!" The fat bandit was rattled as the young woman slammed the handle of her guandao onto his head. She took a few steps back, assuming a fighting stance.

"That is just a warning blow." The young woman stated, priming the blade of her glaive at her opponent. "The next blow will be with this blade." She said in dangerous tone, slashing the blade of her glaive through the air. The sound of a sharp metal cutting through the air could be heard before she assumed her stance.

The fat bandit, along with the other, were visibly rattled. She was able to withstand the fat bandit's heavy attack without showing any sign of fear or worry. The two people the young woman was protecting, the old man and the young girl, were looking at their savior and protector with nervousness and anticipation in their eyes.

With heavy atmosphere in the air, the bandits and the glaive-wielding young woman were looking at each other, and the young woman seemed ready to unleash another attack, this time using the blade of her guandao. Before she could even move, however, they heard a sound from above. It was the sound of something moving in high speed. All of them, including the old man and the young girl, looked up to see the source of the sound.

Words alone weren't enough to explain what they were seeing, as a blond young man seemingly fell from the sky, moving in high speed. It seemed that the spear-wielding young woman was too shocked to even realize that the young man was falling towards her direction. It was soon too late for her to move as the young man landed on her. The impact from his landing was enough to send the young woman flying a few meters behind.

"Hmpf!" The young man, or rather, the boy landed onto her, and unwittingly, had his face buried between her breasts.

"Kyaa!" The young woman squealed in surprise and a little bit in pain as she was sent flying a few meters back by the impact of the boy landing on her. She landed on her back, and the boy on top of her, his face still stuffed between her breasts.

The bandits blinked in confusion. The midget one glanced over his shoulder, looking at the sky, briefly wondering about why there was a kid falling from the sky in the first place. The old man and the young girl also blinked in confusion.

"Urgh…" the boy, Yuuto Kiba, grunted in pain. His Devil wings shrunk before they disappeared. He moved his right hand so that he could push himself up so that he could finally breathe. Unfortunately, it happened that his hand moved onto the young woman's left breast. Kiba's mind was too groggy to think of anything as his hand squeezed the suspiciously squishy object.

"Eek!" The young woman beneath him let out another squeal.

"Huh?" Kiba blinked. Slowly, his mind became clearer before he looked down. Apparently, he didn't notice that he really landed on top of someone, and that someone happened to be a female. His hand was still on the young woman's left breast as he looked down, and their eyes met.

For a few moments, there was only silence. Kiba couldn't help himself but to gape as he looked at the one who cushioned his fall a while ago. His gray eyes were staring into hers, and the boy gulped when he found out that those amber eyes of hers were rather mesmerizing. While he never showed it, as a boy, being attracted to beautiful females wasn't really that strange. Both of them were staring into each other eyes for almost a minute as redness started to spread over the young woman's beautiful visage.

Slowly, as the young woman managed to compose herself, her expression hardened, and her brow furrowed. She clenched her right fist before she threw a punch towards Kiba's face. "U-unhand me, you vile beast!"

"Gah!" Kiba narrowly avoided the punch before he immediately got up and took a few steps aback. The young woman also got up, picked up her guandao before she aimed it at the blond boy, glaring at him. "W-wait!" Kiba raised both hands, as if trying to placate the seemingly slighted young woman, whose face was still red, probably due to embarrassment.

The young woman studied Kiba's face, still pointing the tip of her glaive at him before she heard the sound of the fat bandit from earlier approaching her. She immediately grabbed Kiba's shoulder before she pushed him behind, together with the old man and the young girl she had been protecting.

"Stand back!" The young woman ordered the blond boy before she focused on the approaching fat bandit.

"Teach that bitch a lesson, Fatso!" The midget bandit yelled.

When the fat bandit got closer, the young woman assumed a fighting stance, with the tip of her guandao pointing downward. Then, she kicked the ground and rushed towards the approaching bandit, letting out a loud battle cry. She was extremely fast and Kiba could barely follow her movement with his eyes. In just a short time, the young woman managed to close the distance between her and the fat bandit.

With one swift, brutal move, the young woman disarmed and knocked the bandit down with just one swipe of her guandao. The bandit fell onto the ground, having the wind knocked out of him. Resuming her fighting stance, the glaive-wielding young woman glared at the remaining bandits.

"One down!" The young woman announced. "Who's next?" She glared at the midget bandit. "You?!"

"Huh?!" The midget seemed frightened by the young woman's intense glare. "N-no, not me!" He turned on his heel before he tried to dash away.

"Hey, the hell are you going?!" The lanky bandit shouted as the midget tried to run away.

"There's no way I can win against some super woman who can take Fatso down in one blow!"

"A super woman…?" The young woman spoke darkly. "You insolent pig, don't even think of running away!"

"Gah, no! W-wait, I-I didn't mean- argh!"

Before the midget bandit could even finish, the woman closed the distance between them before she rammed the butt of her weapon onto the bandit's face. A cracking sound could be heard as the attack broke the bandit's nose. Right after being hit on his face, the bandit got his collar seized by the young woman before she hurled him towards the downed fat bandit over her shoulder.

"Now then, you are the last…" the young woman looked at the remaining bandit, priming her glaive at him. "Will you fight or will you escape with your companions?" She glanced at the old man and the young girl she was protecting. "You had destroyed their means of transportation and threatened to rob and harm them. Be thankful that I give you these choices, or else I may have had to kill the three of you on the spot."

The lanky bandit seemed troubled, mulling over his choices before he lowered his head. "…Fine. We'll go."

Seeing that the threat was neutralized, the young woman turned to attend to the ones she was protecting, expecting the bandits to leave. She went to the old man and the young girl, not noticing the lanky bandit brandishing his sword, aiming to attack her from behind while she was preoccupied.

There was an ugly sneer on the bandit's face. He sneaked behind the young woman before he raised his sword over his head, aiming to strike her unprotected back.

"Watch out!"

The young woman was alarmed by the shout from the young girl before she looked behind her and saw the sword coming down. However, before it could even touch her, the blond young man who fell from the sky earlier rushed towards the bandit, immediately grabbing the bandit's wrist and twisting his arm violently, causing the bandit to drop his weapon

As soon as the bandit dropped his sword, the blond young man, Kiba, slammed his palm onto the bandit's chin from below. Then, using his body as a fulcrum, he threw the bandit over his shoulder using a judo move. While he was a weapon user, Kiba was also trained in unarmed combat.

"Urgh!" Falling on his back, the lanky bandit felt his head was spinning, thanks to Kiba's palm attack earlier. Then he realized that the blond boy was standing over him, his right foot on his chest. In his right hand was a sword with black blade, glinting ominously under the ray of sunlight, and the tip of the sword was pointed at the bandit's face.

"Trying to attack a woman from behind…" Kiba's tone was dangerously low as he spoke, his gray eyes glaring at the bandit below him. "Have you no shame?" The tip of the sword was one inch away from the bandit's brow, and the sword would stab through his skull with just a push. "Preying on the weak but running away from the sight of the strong, you're definitely scum." He spat out those words to the downed bandit who was completely under his mercy.

The bandit was agitated, beads of sweat starting to form on his face.

"Now, what will you say at time like this?" Kiba asked with a smile, but the smile didn't seem to quite reach his eyes.

"I…" trembling, the bandit began. "I-I yield."

"Good," Kiba nodded, smiling in satisfaction. "Alright, then." He pulled back his sword. Before the bandit could breathe out a sigh of relief, the blond boy stomped onto the bandit's crotch, and the bandit screamed. The sheer pain from being stomped on his sensitive area was enough to make him pass out, foaming at the mouth as he did so.

Resting his demonic sword over his shoulder, Kiba looked at the young woman and the people she had been protecting, and they were staring at him in total confusion. Then the young woman cleared her throat, composing herself before she smiled at him.

"Thank you for saving my life," the young woman expressed her gratitude to Kiba. "If you hadn't made that move, I might be dead now."

"It's nothing…" Kiba said, lowering his sword before it vanished. The young woman raised one eyebrow, noting the disappearance of the sword. "I didn't do much. You're the one who beat them up," he gestured at the unconscious bandits that the young woman had beaten up earlier. "And you also saved my life earlier. You cushioned my fall, you see?"

"Falling?" The young woman looked at Kiba skeptically as she glanced up, looking at the sky. "You were falling from above?"

"It's a long story." Kiba said. Somehow, thanks to the shards of the broken mirror earlier, he had a feeling that he had been transported into an alternate dimension. Judging from the look of their surroundings and the clothing the young woman was wearing, he could tell that he might be right.

"A long story…" the young woman muttered. She seemed to be thinking about something.

"So…" Kiba looked at the bandits and then at the old man and the young girl the young woman had been protecting earlier. "What are you going to do with them?" He asked.

"I shall gather them up and tie them together as a reminder of their crime," the young woman said, pointing at the unconscious bandits. "And I shall escort them to the nearest town. With their carriage destroyed and mule killed, I suppose I shall be accompanying them for the time being. There might be more bandits waiting along the way."

"I see…" Kiba mused.

Then, the young woman lowered her head, as if bowing. "Even so, I beg your pardon, f-for..." she hesitated. "For calling you 'vile beast' earlier. I-it was a spur of the moment, I couldn't think very clearly at that time." It sounded like she was apologizing to Kiba for almost punching him after him landing on her earlier.

"Nah, it's hardly a big deal. I mean, I was the one at fault here, so I kind of deserved it if you socked my face earlier and called me a vile beast." Kiba said.

Then, there was silence. Both Kiba and the young woman didn't say anything. The young girl was about to say something, but was silenced by the old man who was with her.

"…Who are you?" Kiba finally asked after a few minutes of silence.

The young woman blinked a few times before she nodded and smiled. "Oh, pardon me. I haven't introduced myself yet. My family name is Kan, my first name is U, and my common name is Unchou. I have travelled from Yuushuu to complete a mission of mine."

"Kan… U?" Kiba spoke the young woman's name. "Kan'u? W-wait," he looked at the young woman. "Did you say 'Kan'u'? Your name is Kan'u?"

The young woman, Kan'u nodded. "Yes, Kan'u is my name."

Blinking a few times, Kiba brought his hand to his chin. He recognized that name. In his spare time, he had been reading a lot of books, including Romance of the Three Kingdoms. Kan'u, or Guan Yu by the Chinese, was one of the important figure during the Three Kingdoms period, a general serving under the warlord Ryuubi or Liu Bei.

He looked at Kan'u's face. She claimed to be Kan'u, but Kiba remembered reading that in Romance of the Three Kingdoms, Kan'u was a middle-aged man with thick, black beard. But this Kan'u was a beautiful female. A beautiful female with a stunning body, as a matter of fact.

Kiba wasn't sure what to think of anymore. Perhaps that fall earlier had been scrambling his brain to the point where he might be hearing and seeing things that weren't really there.

"Are you alright?" Kan'u asked, seemingly concerned. "And, umm... might you grace me with your name?"

"My name? Oh, sure." Well, he would have time to think about Kan'u being a female some other time. "My name is Yuuto Kiba. It's nice to meet you, uh… Kan'u?"

Yes, he really needed to think about it some other time. Things were getting more and more confusing here. Just when he thought that his life couldn't get any weirder than it already was, he was proven wrong. He thought that having his friend summoning a breast goddess from the other world couldn't be topped for its utter weirdness, but he was wrong. Very, very wrong.
