Life 1: New School Term, Beginning Of Trouble

In his life, there are times when one must prepare themselves to do what must be done for the greater good. It is to this feeling that Shidou Haruka woke up to every morning and honestly, it is not a feeling he likes but it needs to be done nonetheless because most of all, it is Monday, the first day of school for every week.

Everyone hates Monday, except maybe those workaholic people who are practically married to their job or an all around honor student. He is surely neither of those but his biological alarm clock begged to differ.

Morning in the Shidou household for the past two years consists of Haruka waking up early, usually around five to six at most. Do a little bit of stretching and then get ready for the day, which means morning shower, waking up Irina, ironing clothes and cooking breakfast generally.

Of course, the first question asked would be 'where are their parents?' The Shidou sibling that consists of Haruka and Irina are left to stay in Japan while their parents went to England for work-related matter. Though why they took so long when their father is a pastor is unknown to him but he is not the type to complain much, especially since Irina is happy that they didn't have to move away with their parents and she can enjoy her time with their childhood friend.

It is generally agreed that ironing clothes came first and what comes next depends on whether Irina is already up or not. In this case, she's not, mostly because it's Monday and because she's up until late at night talking with their childhood friend for hours, mostly about club activities since they're part of the Light Music club, something about life performance in this year's school festival and writing a new song. He didn't quite listen to them much since her remembered about the regional tournament he'll participate in with the kendo club and the training they will need.

After ironing their clothes Haruka walk up the stairs to the second floor and entered Irina's room where she's sleeping peacefully while drooling. Her sleeping posture is terrible and there's nothing girlish about her. This is Shidou Irina though so Haruka won't have it any other way. Haruka began to shake her to wake her up.

"Irina, wake up."

No response.

"Irina, wake up!"

Still no response. Haruka sighs and went to Irina's desk. There should be an item that could help wake her up. He found one and began smiling evilly as he went back to Irina's bedside and raise the item just above her face. Irina began to tremble and sweat for no reason as if instinctively knowing that something bad is about to happen to her. She's not wrong as Haruka release his grip on the item.

He dropped an encyclopedia on her face and it smacked her hard.

"Gyyyyyyyyyyyyyyyyyyyyyyyaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa!"

Her scream probably woke up the neighbors but Haruka felt a sense of satisfaction when he saw her jumping from her bed with a red face and running around while screaming in pain. Yup, this is his sister and he wouldn't have her any other way.

Irina rubs her sore nose as she drinks the milk her brother gave her through a straw. Haruka did feel slightly bad when seeing her teary eyes but it won't stop him from doing that again.

"Uuu, onii-sama, that's cruel. What if you ruin your cute sister's face?"

Irina pouted as she drinks her milk, slurping it loudly while Haruka cooks. The big brother chuckled as he flipped the egg on the pan and turn to his sister while grinning.

"Hey, there's no cuteness to ruin since there's nothing cute at all in the first place."

"Muu, onii-sama is mean."

"Yeah yeah, just go do your morning ritual or something. Breakfast is almost ready."

Haruka said while lazily pointing to his side, more specifically, he is referring to the house beside theirs, the house of their neighbor and childhood friend, Hyoudou Issei. Irina immediately finishes drinking her milk and happily ran up the stair back to her room leaving Haruka to finish making breakfast. Every Monday, Friday, and Sunday Issei would be invited to have breakfast and dinner with them. Haruka might sometime complain about cooking more but he does enjoy their time together.

Irina opened the window of her balcony and jumped over the railing onto a tree branch and then again onto the balcony next to hers. She opened the window and entered the room. It is the room of her childhood friend, Hyoudou Issei. The brown-haired teen is still sleeping like he tends to be during six thirty. But since she's up, then Issei must also be up to suffer the morning together with her. She might love her brother very much but she doesn't like being woken up too early and misery loves company, especially if the company is a certain childhood friend who is currently sleeping.

Irina crouched down beside Issei's bed. She lightly blushed when Issei suddenly turn and his sleeping face came close to hers. Irina smiled and watch him sleep for a few more minutes until she decided to wake him up.

"Ise-kun, wake up."

Irina poked his cheek with her index finger. The boy groaned and turn away to face the wall.

"Ugh, ten more minutes."

Irina poked his back this time.

"Wake up. If you don't wake up then I'll kiss you~"

Irina whispered into his ear. Suddenly Issei turn again ad this time he grabbed her and pull her into the bed with him and hug her like a pillow. Irina who was caught off guard got pulled in and is blushing heavily from how close she is with Issei's face.

"E-ehhh, Ise-kun?! This, this is too soon!"

Issei is still sleeping soundly while Irina tried to escape from his strong grip. The more she struggled, the more his grip seem to become stronger. Irina gave up and decided to wait for him to wake up. She touched his cheek and smiled.

"Ise-kun."

"Uuu, Irina…"

Irina blushed when Issei uttered her name in his sleep. He also pulled her closer to his chest making her heart beat faster being so close to him. Irina look up to her childhood friend's face and saw his lips. It's a chance! She gulped as she lean in closer and…

"Oi, when will you love birds wake up?"

"Ehh, Onii-sama?!"

Irina freezes and slowly face her older brother who is now also in the room looking down on the two younger teens. He wearing a pink apron over his school uniform that has the words 'please do nothing to the cook' printed on it. Haruka sighs and brandished an encyclopedia which made Irina whimper in fear. He considered for a bit and shook his head. He put away the encyclopedia and this time took out a bottle of water.

Three guesses about what happens next.

"Gha! Ahhh! What the hell?!"

Hyoudou Issei immediately woke up with face drenched in water. Haruka chuckled and drink the remaining water in the bottle. He then turn back to the window and jump to Irina's balcony with practiced ease.

"Get ready for school you two, and no kissing!"

"W-wha?!"

Issei didn't quite hear what Haruka said because he's more concerned with being wet but Irina heard him and blushed hard as she try to hide her face behind her hands. Sometimes she really hates her brother whose laugh can be heard from their house as he went back to the kitchen. At the same time, Issei's bedroom door opened and Issei's mother came in.

"Ara, I heard screaming coming from here but it's just Irina-chan. Good morning dear."

"Good morning obaa-san."

Irina politely greeted mrs Hyoudou. Issei's mother is not surprised that Irina is in Issei's room. She knew the girl likes to jump over from the tree between their two houses and it's not the first time she caught Irina in Issei's room after jumping from the tree. It's also not the first time Irina came to wake Issei up but it's certainly the first time Issei woke up with his face wet.

"Ara Issei, why are you wet?"

"It's Haru-nii."

That simple answer is enough to tell Issei's mother what happened.

"I see. Well, Irina-chan came to take you for breakfast so you better prepare quickly. You don't want to keep Haruka-kun waiting, right?"

Issei mumbled something Irina can't quite hear but it's probably just a few curses for Haruka. Overall, it's just another normal morning with Haruka forcing Irina to wake up early and Irina waking up Issei... though that went differently this time.

After breakfast, the three of them went to school together just like every other day. Irina and Issei would walk in front together while Haruka follow them from behind. Issei and Irina are 2nd year students in Kuoh academy and are in the same class and the same club while Haruka is a third year and captain of the kendo club.

At first, there was no kendo club for boys in Kuoh academy. But after Haruka shows magnificent skill and talent in kendo which won him several competitions when he was still in middle school, he managed to establish a boys kendo club which is mixed with girls. He had won them two competitions so far and he planned for a third, but this time as a team since those victories are mostly in single matches. The boys' kendo club members lack training and talented members and he plan to change that before he graduates.

Meanwhile Issei and Irina as part of the light music club had participated in past school festivals and several gigs. This year though they can't participate unless they can replace the members that graduated. Irina and Issei are currently the only members of the light music club and they desperately need at least two new members, which is what they're talking about right now.

When they reached the school gate, the trio were greeted by two familiar girls.

"Shidou-senpai, I know you would come early. And good morning, Ise-kun!"

"Hello Ace! Irina-chan! Hyoudou-kun"

Haruka was greeted by two of his club mates when he reached the school. The first who greeted him is Katase, a girl with short pinkish hair. She's a cute girl and has a crush on Issei who is oblivious to her feelings... and Irina's. Haruka wonder how the dense idiot cannot notice how Katase and Irina would blush around him or would glare at each other when they're in close proximity.

The second girl is Murayama who likes to call him Ace since he's the ace of the kendo club. She and Katase are second year students in the same class as Issei. She has long brownish hair tied in twintail though hers is thinner and shorter than Irina's.

"Morning girls!"

"Good morning Murayama-chan... Katase."

Issei enthusiastically greeted his classmates while Irina politely greet Murayama... and send a small glare at Katase who returned it in kind, especially seeing how close Irina is with Issei. Haruka can only shook his head in amusement as they watch the two rivals for Issei's affection glare at each other like every other morning. Murayama too watch the two in amusement as she walk up to the kendo club's ace.

"This again."

"Maa, it's fine isn't it? It's interesting to see after all."

Murayama laughed. To be honest, Murayama thought that Katase has no chance with Issei with Irina around but she doesn't have the heart to tell her that, at least for now. Katase has no chance in beating the childhood friend and the only reason Issei and Irina is not dating is because the boy is dense. It would be a different matter if Issei see Irina only as a friend or as a sister which is a trap-hole childhood friends often find themselves in but Murayama had seen that there is something there between them and again, she doesn't have the heart to tell her friend.

While the five of them walk together, someone is observing them from afar with a smile on her lips as her long crimson hair sway in the wind. Rias Gremory sat on a windowsill looking down on the five students with interest and she focus that interest on one Hyoudou Issei. Unknown to her though, someone was looking up at that moment and saw her too. Shidou Haruka saw Rias Gremory looking at them, at one of them, and narrowed his eyes.

He never liked Rias Gremory. He doesn't know why and can't explain it but everything about her just screams abnormal. Any interest from her should be regarded with suspicion. Who knows what unsavory things she's involved in.

Little did he know that this very interest will lead him along with his sister and childhood friend into a world they never knew before.

This is just an idea I got after reviewing my school life story. So the premise here is 'What if Shidou Touji and his wife doesn't want to involve their children with the church and instead give them a normal life?' So Haruka and Irina here are unaware of the supernatural world and lived on as regular people. Irina is not an exorcist or anything and so is her brother. Due to Touji's choice, Irina and Haruka never moved away and stayed so Issei and the Shidou siblings kept being friends. Since he still has his friends, Issei never met the old man that taught him about oppai but instead become a dense schoolboy protagonist who has his childhood friend and his classmate crushing on him.

This time I'm really focusing on the humans so unlike before, the humans of Kuoh academy will play parts in the story. Humans like Kiyome Abe, Kiryuu Aika, Murayama, Katase, and hell, maybe even Matsuda and Motohama. I take the basic setting from my school life stories like Issei and Irina in the light music club and Haruka is the ace of the kendo club. Now, all main characters will be humans and will center around the humans who are neutral in the supernatural world like the students. Well, I hope that's the outcome anyway. So even if Rias Gremory already appear in the first chapter, don't expect any of the main characters to become a devil. I don't like that. And even if they do, it will be a cold day in hell before they become part of Gremory's peerage. I'd rather give them to Sona or Sairaorg or even Seekavira... not that I would.

As for pairing, of course the main pairing will be the usual. Issei x Irina and Haruka x Xenovia. Harem is optional but I don't accept non-humans which means no devils, angels, or fallens, or youkai, or anything really. Just humans.
