Author's Note: Sorry for the delay for this chapter. I'll try to update faster next time. Thanks for all the reviews, favs and alerts!

I noticed I made Yukio a little OOC the last chapter and for this one… I'm sorry about that but I don't know how to change it D:

This chapter is not beta-ed

Disclaimer: AoE and KHR don't belong to me.

Chapter 2

Rin followed the trail of what he guessed is a demon. Having sensed it from outside, Rin knew it would be powerful.

As he searched for the source, Rin thought of why Yukio didn't ban his Flames like the usual. It must be because our clients have Flames, Rin surmised. They wouldn't find my Flames weird.

All of a sudden, pain shot through Rin's arm as he blocked an attack due to instinct. Rin grumbled to himself. Thinking while in enemy territory can kill you.

Looking around for the demon, Rin saw that he was dealing against a dog-like ghoul. He grinned to himself. Nothing I can't handle.

Mukuro leaned near Yukio's ear which made the exorcist uncomfortable. "Everything with life has the Dying Will Flame. I happen to sense something… different from him."

Yukio was confused with what Mukuro said. "Dying will flame?"

Reborn jumped up to a waist-height wall nearby. "The Flames you saw earlier are the Dying Will Flames," Reborn explained. "There are seven typed. But we'll get to that some other time."

Reborn turned to Mukuro, "We'll talk later."

Mukuro nodded and smiled mischievously. "I'm rather surprised to see the Sky Flame in a demon. Let alone his son."

Tsuna shrieked, "Demon?" but everyone ignored him.

Yukio stared at Mukuro with worry more than with confusion. Seeing this, Mukuro explained the power of his right eye. The Realm Of Hell* was connected to Gehena. However, it would not summon demons, but allow Mukuro to cast real illusions.

Reborn cut in before more could be said. He was interested in something more. "That's enough about Mukuro's eye. You said Rin Okumura's Flame was Sky?"

Rin was having trouble with the ghouls. He thought that there was only one. However, once he killed the first ghoul, two more came out of nowhere. Rin smacked himself mentally. He forgot his earlier assessment of the demon's power in the building.

Now, Rin was fighting five ghouls at once. A ghoul jumped towards Rin in an attempt to lash out its long claws. Rin blocked it with his sword, but the ghoul was proving to be slightly stronger. The other four ghouls attacked as one. Rin jumped after successfully pushing the first ghoul away due to the adrenaline pumping on his veins. However, the ghoul managed to scratch him in the process.

Rin could feel a burning sensation crawl up from his wounded leg travelling towards his upper body. He grit his teeth and willed his Flame to increase in order to deal with the problem.

Rin never noticed the difference of the Flame which answered his call.

Tsuna felt a strange feeling overcome him. It felt like the time when Dino showed them his Sky Flame. As well as the time when Byakuran, Uni, and Tsuna were together in the dome of Sky Flame. He didn't understand what it was, but he reckoned it to be a quirk of the Sky Flame users.

Tsuna jumped when Reborn's voice interrupted his thoughts. "What were you thinking about Dame-Tsuna?"

Tsuna squirmed slightly. "J-just a feeling. It's s-something to do with the Sky-"

Before he could finish his sentence, an explosion rang from the building Rin ran to. Tsuna immediately ran inside. Lambo, being on Tsuna's shoulder, and Reborn, who was at Tsuna's head, got dragged in. Yukio looked worried for his brother and also rushed inside. The others, except Hibari, Mukuro and Chrome followed the brunette.

Mukuro shrugged and walked leisurely with Chrome. Before getting too far, he glanced back at Hibari. "Skylark-kun~" Mukuro said in a singsong voice. "You better come inside as well."

Hibari glared at the pineapple-haired illusionist before going on the other direction. He didn't know Mukuro casted an illusion that made him go back inside every time he tried to go out of the place. Hibari growled when he noticed it.

He went inside the building that the other guardians went in. He swore to bite Mukuro to death for what he did.

Tsuna remembered this place as their first encounter with Mukuro and his gang. He looked around and saw some newer cracks and holes on the walls. That probably meant he was close to Rin and whatever he was fighting. Tsuna stopped to catch his breath from continuous running.

"Tenth!" Hayato cried out when he caught up with Tsuna. "Where are we going?"

Tsuna shook his head to tell him that he didn't know as well. "I… I just got this feeling that if we don't find Rin-san, something bad will happen."

Hayato nodded. "It's your hyper-intuition then, Tenth?" When his boss nodded, Hayato added: "Let's wait for the others. Baseball-freak(Yamamoto) or Mukuro can find him immediately with their box animals."

Soon enough, the other guardians and Yukio, minus the three that didn't join them in leaving, arrived at where Tsuna and Hayato waited. After explaining their problem about finding Rin, Takeshi brought out Jirou – his dog box animal – and asked him to seek out other Sky Flames. It was one of the abilities that Takeshi found out about Jirou. He could find any of the different Flames within an area.

Jirou sniffed around and ran off, leaving the guardians to follow him.

Yukio looked on in surprise as a dog materialized. It had blue flames adorning its whole body. It made him really curious about them, their abilities, and their connection to Satan's flames.

Rin coughed as miasma flooded the air. His body can't hold on for much longer. His vision became blurry. He could feel his body wavering. Rin didn't expect to be trapped by a demon that looked like a human.

He knew about demons possessing humans. Heck, Rin even awakened his demonic powers because of one! He just didn't expect to see one in here.

(Flashback)

"Look out! Behind!" shouted someone.

Rin quickly swung at his back and incinerated another ghoul. He looked around and saw a boy with brown hair and eyes clutching a large book. "Come near me! It's dangerous here!" the boy nodded and ran to Rin. "What's your name?"

The boy remained in silence. He watched Rin destroy the seemingly limitless amount of ghouls.

Rin panted from using his flames too much and the damage dealt to him. "This is getting nowhere. I'm getting tired," Rin said and wiped his chin with the back of his left hand while his right still clutched Kurikara that was lit up with his flame.

The boy laughed in a creepy manner. "I see. You still have no control over that flame."

"Huh?" Rin turned around in surprise.

A huge mistake to make as miasma gas shot out from the boys' hands and engulfed him.

(End of flashback)

The boy laughed at how Rin struggled. "Master Astaroth will be happy. Even his Father would be if I bring you back to Gehena."

Rin glared at the best he could while his strength wavered more.

A dog covered with blue flames tackled the brown haired boy. Several people also came rushing after it. All of them froze at the sight of the boy. "Fuuta?" one of them asked in confusion.

Rin looked puzzled They knew the boy? he thought. Rin coughed and remembered his current predicament with the miasma. His harsh cough seemed to wake the shocked guardians into action.

One of the white-haired teens went next to Rin immediately. He remembered the guy to be Sasagawa Ryohei. Ryohei took out his Sun Trowel and healed Rin. The others stood in front of them, ready to defend.

"Hey Tsuna," called out Takeshi without taking their eyes off the boy—Fuuta. "I thought he had Sky Flame? I can see Rain Flame on him though."

Tsuna, in Hyper Dying Will Mode, looked slightly at Rin before telling Takeshi: "Jirou found him by looking for Sky Flame."

"Ah you're right!" Takeshi grinned stupidly.

"Isn't Sky supposed to be the balance of all 6 Flames?" Ryohei asked in bewilderment.

Tsuna looked at Reborn who jumped down from his head beforehand. "Any clue, Reborn?"

"I'll tell you later," Reborn replied. "Deal with this first."

Yukio cocked his gun. "Please provide assistance to my brother while I deal with this."

"Very well," Reborn said.

Yukio took out a vial with Holy Water and threw its contents on the child. Fuuta screamed at the contact with the water.

"Damned exorcist!" the child snarled through the pain. "I'LL KILL YOU!"

Yukio smiled at him and pointed his gun. "Did you say something?"

"You wouldn't shoot a human!" the possessed boy said smugly.

"You want to bet on that?" Yukio said and lined his gun up for a shot.

The child laughed again, "You won't shoot!"

The sound of a gun being shot filled the air. The child held a surprised expression before closing his eyes. Yukio shot him in the shoulder.

"What did you do to Fuuta?" Tsuna glared at Yukio. Nobody hurts his Family.

"Calm down Dame-Tsuna," Reborn said from Fuuta's side. "He's only unconscious."

Yukio sheathed his gun. "I merely hit him with a tranquilizer. I don't kill humans." He walked over to Rin. "Are you alright Nii-san?"

"As alright as I can be," Rin grumbled while Ryohei still healed him.

"Uhm… Is Fuuta going to be fine?" Tsuna asked hesistantly. He left his dying will mode after Reborn calmed him.

"He'll be fine." Rin stood as Ryohei finished healing him. He stretched and sighed contently. "I feel as good as new. Thanks a lot Sasagawa-san!"

Ryohei shouted, "No problem to the extreme!"

Yukio and Rin looked thoughtful for a moment. Rin thumped a fist into his palm in a manner of blind inspiration. "Did you guys see the demon?"

Tsuna and his guardians questions, "The demon?"

"Guess not." Rin sighed in exasperation. "Then did you at least see my blue flames?"

"Yup!" Takeshi said while grinning. "This is the first time I saw a Sky bearer that had unbalanced Flames. Mukuro said that you had-"

"Kufufu." Mukuro materialized next to Rin who jumped in surprise. "I assure you my earlier assessment is correct."

"What the heck is this guy?" Rin blurted out.

Mukuro ignored Rin. "He does have a balanced Sky Flame."

Yukio coughed to get their attention. "I think we deserve an explanation about this Dying Will Flame you've been talking about."

Reborn looked up to him. "The Dying Will Flame is a high-density form of energy that is refined from one's own life-force. It also resonates with one's emotions. There are seven types of these."

Reborn gestured for the guardians to show their Flame. "Tsuna has the Sky Flame with the attribute of Harmony. Yamamoto has Rain which is Tranquility. Ryohei has Sun that is Activation. Mukuro has the Mist which is Construction. Lambo has Lightning having the attribute of Hardening. Gokudera has 5 types, but you already know the other 3. His main Flame, the red one, is Storm which would be Disintegration. The violet flame is Cloud which is propagation."

Yukio nodded in understanding. Rin still looked confused. "Does that mean I have Rain Flame?"

"No," Mukuro said with exasperation. "Your blue flames are not the same as the Dying Will. The have similarities, but they're not the same."

"Oh. I see," said Rin, even though he didn't understand. "Then what do I have?"

"Sky."

A/N: Sorry for the delay. I was waiting for responses from my two betas. For Rin's Flame, I'll explain that on the next chapter.
