I've accepted Storylover213's challenge fic given that I found it was an interesting idea...Anyway the challenge is for a OC who would take Issei as Main character and in Rias peerage (meaning that he starts out Human) along with a OC Sacred Gear that would give the Fic a slight Bleach crossover. The OC's Sacred Gear would either be Ichigo's Zanpaktou Zangetsu or Ulquiorra's Segunda Etapa form the fic would follow the cannon with whatever changes I would want to make of it also the OC unlike Issei isn't a Ero-gaki and unlike Issei has some fighting skills having taken Martial Arts classes for a time before stopping once he got into high school also the OC will have a Harem of however many girls I like with Rias as the Alpha Female of the Harem.

Hopefully my take will catch your interest and here's the first chapter, I know its a a bit short but I figured I may as well put up what I've got at the moment.

...

The silver haired sixteen year old teenager trudged downstairs with a yawn, dressed in the Kuoh Academy uniform as he entered the kitchen as he spoke "Morning Keiko-nee"

"Morning Yukio-kun" replied the shoulder length blonde haired young woman smiling back at him as she set the two plates of breakfast onto the table, taking her seat opposite him as she appraised her younger brother's appearance.

Yukio's scruffy silver hair was pulling back into short stub of a ponytail that was held in place by an elastic band, while the front reached down to just past his eyebrows in a spiky pattern and could hide his dark red eyes on occasion. He stood at five foot eight with a lean build that had come from his martial arts lessons when he was younger.

"So how's school?" She asked, working as a nurse at a hospital during most of the day meant that there only time to talk would be in the mornings before she had to go.

"Alright…Still trying to get use to it" Yukio replied in between mouthfuls of food noticing the time as he wolfed down what he had left before grabbing his bag and running out the door as he called behind him

"Bye nee-san!"

Yukio stretched as he walked to school, his sister had looked after him since he'd lost his parents when he was about eight but he still wanted to protect her so had taken to learning a few different martial arts styles until he started at Kuoh, more from Keiko telling him that she could take care of herself.

Reaching the school gates he was reminded of the boy/girl ratio of the school, before his eyes picked up the popular students of the school which consisted of Rias Gremory and Akeno Himejima, the two school idols, Yuuto Kiba, otherwise known as the handsome prince, and Koneko Toujou, who was considered the school mascot.

Yukio himself was use to being considered helpful and had tutored a few of the girls from his class, although he wasn't aware of the small fan club that had formed for him cause of it.

As he headed inside the school building he didn't notice the pair of looks he was getting from the two school idols Rias speaking up once he was no longer in sight "Who was that?"

"Oh…That's Yukio Hosokawa…a few of the girls like him because he doesn't mind tutoring those that need it from his class" Akeno replied looking to her friend to see Rias nodding

"Interesting…"

"Looks like time's up, Kiryu-san" Yukio spoke friendly, the glasses wearing black haired girl smiling as they both packed there things away before starting to walk out.

"Thanks for you're help Yukio-kun, I'd be stuck on that for a while otherwise" Kiryu spoke with a smile as she lied, she understood it but had figured it would give her reason to spend time around him splitting ways at the school gates, each headed towards there own homes.

Yukio broke into a jog so he could get home so he could finish his own school work, his ears pricking up as he heard a girly scream for help. Skidding on his feet he turned towards the direction of the noise his eyebrows lowering as he decided to help the girl that was in trouble.

Only a few minutes passed till he found himself looking at a man trying to force a black haired girl against the wall, not thinking for another second as Yukio rushed forward. He threw a punch at the man knocking him back and away from the girl as a serious look dominated his face. He relaxed as he figured that the man was unconscious turning to speak to the girl only to find a sharp pain piercing his stomach.

"Sorry. You were a threat to us, so we decided to get rid of you early. If you want to hold a grudge, then hate the God who put the Sacred Gear inside you." Yuuma spoke with a cold smile as she pulled the light spear from his stomach flying off as Yukio collapsed onto the ground.

'I can't believe I died cause of helping someone…I wish…' He thought his eyes growing heavy as the crimson glow of a magic circle appeared no more then a few feet away from him.

Yukio woke up with his alarm as usual switching off the annoying sound as he turned over and snuggled into the warmth next to him in an attempt to savour a few more moments of sleep, his eyes widening upon hearing the soft moan from it as he found himself looking into the peaceful face of Rias Gremory.

Backing up instantly, Yukio swore he didn't go to bed last night with her before his eyes widened at not remembering going to bed at all the previous night. He caught his traitorous eyes trailing down her beautiful body, his cheeks reddening as he looked away to calm himself down.

'Rias Gremory…is sleeping in my bed…naked…' He thought, his mind frying for a moment before he found himself recalling that he'd been killed the night before as he moved his hand to his stomach to find not even a scar.

"Yukio-kun! Wake up" Keiko called, Yukio jumping slightly at what his sister would think of Rias being in here with him as he turned to wake her. Keiko had always been protective of him in that manner and even if he didn't know what had happened last night she'd assume the worst and blame it all on Rias.

"Come on Sempai…you need to get up and dressed" Yukio spoke, trying to keep the panic from his voice as he gently shook her shoulder, Rias stirring as Yukio threw her shirt on her head as he started to pull on his own clothes.

Rias pulled the shirt from off her head as she sleepily looked around the room, giggling as she watched Yukio hop around his room as he attempted to pull his slacks up, his shirt was open and a panicked look was on his face.

"Yukio…?" She asked, confused as Yukio finally managed to fasten his slacks as he turned to face her. He blushed as he remembered her state of dress, turning back around as he spoke seriously

"You should hurry and get dressed before my sister suspects something…but you're going to have to explain things later"

"Yukio-kun, come on you're breakfast is done" Keiko called, Yukio fastening his shirt before pulling on his blazer as Rias asked

"Why…?"

"She's protective of me and finding you in here like that…well you may have her temper directed at you at full force…not a good thing…I swear she could take on the Maou with her death glare" Yukio spoke, shuddering at the last time he was the target of it. Rias' eyes were wide as she decided to get dressed not wanting to get on the bad side of her new servant's sister.

"Please just wait here till I call for you Sempai…" Yukio spoke as he checked there wasn't anything else he needed to do before leaving the room closing the door behind him before heading downstairs. He smiled sheepishly as he spotted Keiko looking at him sternly with her hands on her hips as she spoke

"You're going to be late now…and you're going to need this" She held out an elastic band for him, Yukio scratching the back of his head as he accepted it with his other hand. Fixing his hair in a few seconds he thanked her as she turned to head into the kitchen as she spoke

"Who is she?" Yukio froze for a moment, looking at her back as he wondered how she knew as he lied

"I don't know what you're talking about, Onee-san…I just had trouble getting up today"

"Don't lie…it's not something you can do" Keiko spoke seriously as Yukio gulped as she turned to look at him angrily

"She had better not have corrupted my little Nii-kun otherwise I'll have to teach her a lesson" Her eyes were ablaze as she tightened her clutch on the wooden spoon in her hand, Yukio stepped back from her as he spoke

"Nothing happened…" Keiko searched his face for a few moments before nodding to herself as she turned to enter the kitchen as she called behind her

"I suppose she will want some breakfast as well" Yukio sighed in relief, having managed to take the brunt of his sister's anger as he headed back upstairs, jumping at seeing a dressed and ready Rias waiting on the landing, nervous over what she had heard

"Don't worry Sempai…You'll just have to endure a twenty questions now" Yukio spoke with as best a relaxed smile that he could manage, given the whole confusing morning he'd been having.

Sitting in the kitchen, an uncomfortable atmosphere filled the room; Keiko seemed to keep her stern gaze between the two others, Yukio avoiding it as much as possible by looking at his plate while Rias answered "Yukio-kun was just helping me with my studies last night…we must've fell asleep when we took a small break"

Keiko took a moment to swallow the mouthful of food before looking to Yukio as she spoke "I didn't know Nii-kun was that smart"

Yukio blushed as he looked up to his sister; she only called him 'Nii-kun' in front of any girl. His eyes widened at the hollow look in his sister's eyes as he heard Rias whisper into his ear "I'm sorry... It looked like it would become troublesome, so I used my power"

'Power? What power?' Yukio thought as he turned to look at her, Rias smiling friendly as she turned back to Keiko who seemed to have calmed down with the story she'd given her, Yukio looking confused between the two before jumping slightly as Rias spoke

"Don't waste Onee-sama's food..." Yukio blushed as he finished his meal, catching glimpses of Rias' elegant eating next to him.

The pair's walk to school seemed to be filled with the confused and, mostly, angry stares from other students

"Why is he with Rias-oneesama?"

"How could she pick him…I'm so much better?"

"No! Yukio-kun has been taken by Onee-sama" The last comment was from one of the few girls that liked Yukio, the silver haired boy blushing as Rias giggled as they reached the school gates, accepting her bag from Yukio as she spoke

"I will send someone to you afterwards. I'll see you after school."

Yukio nodded as she walked off, trying to come to terms with all that have happened this morning, looking up as he heard Kiryu spoke up annoyed "How could you hide the fact you're with Rias-oneesama?"

"I'm not with Sempai…we just happened to be walking the same way" Yukio rebuked as he stepped back, his hands up in defence as she calmed down, only for more rumours starting up.

The school day seemed to stretch by as he had to put up with the rumours about him and Rias, some of the boys making threats to kick his ass if he didn't break up with her. The thought of them trying made him laugh, even if he'd stopped taking martial arts classes he still remembered most of it.

He was curious over who Rias would be sending to collect him as he packed his schoolbag up, looking up as he heard a voice from the door

"Hi, how are you doing?" Looking over he found Yuuto Kiba standing before his desk, the girls screaming with joy at the handsome prince's appearance in there class room.

"I'm fine…Did Gremory-sempai ask you to…?" Yukio spoke confused as Yuuto nodded as he added

"Would you follow me?" Yukio stood up as he grabbed his bag, the girls screaming up about the pair of them being some sort of couple as Yukio thought confused

'What the big deal about us walking together'
