Takes place in a world with no supernatural happening. This story is purely school life since I wonder why Highschool DxD has 'Highschool' in its title when the 'school' part is not very important. This is the Issei x Irina route to my 'School Years' fic.

Let's start the Light Music Club!

Scene 1:

-Issei pov-

Greetings. My name is Hyoudou Issei. I'll do a short introduction of myself before we get into the main event. I'm a second year sophomore in Kuoh academy. Overall, I'm a normal student. I'm not like Vali who is very popular due to his image of a bad boy, which he actually is, or like Haruka who is the ace of the kendo club. Unlike them, I score average in test, I look average, and I'm overall an average student stuck as friends with the most popular groups of the academy.

There's no need to speak about Haruka's fame. That damn pretty boy is very popular due to his good looks and status as the ace of the kendo club. A lot of girls, especially in the kendo club, have a crush on him. There are a few reasons why he is still single despite everything. First, he is more focused on kendo. There's a reason he is the ace after all. Second is his closeness with the group of three beautiful seniors, the infamous Twintail Trio. In that regard though, I think that they're the major source of his stress. But still… damn that guy! It is obvious that Serafall-senpai has a crush on him! Why can't he see it?! If I were him, I'd be happy to be Serafall-senpai's boyfriend and be smothered in her wonderful oppai!

Ehm, well, leaving that lucky bastard aside, I am also friends with Kusanagi Vali. He is the little brother of Kusanagi Momoka-senpai, one of the twintail trio, and another popular guy in school. If Haruka is the popular prince-like kind of guy, Vali is a bad boy type. It doesn't help that he is openly involved in a gang, their leader even. At least his group just went around having fun and even helping people instead of causing trouble. He is also cool, even I will admit that. But he is hard to approach. Not because he is dangerous or anything but because he always has Kuroka by his side. Yup, he is somewhat claimed by Kuroka unofficially with how near inseparable they are. Damn that lucky bastard! Kuroka is another one of the school's top beauty! Why are my male friends claimed by the top beauties! What about me?!

And then there is me, the average guy of the group. Average brain, average looks, average ability, all average… well, if you are discounting my somewhat perverse nature. Yes, Hyoudou Issei is a pervert. Which is why I have a dream… and that dream is to make a harem!

Now, as I dramatically declare my dream with a fist held in my chest, my ears picked up a sound that I felt like I know all too well although I cannot put it.

"Hmm?"

I look behind me to where the source of the sound is and panicked when I saw Matsuda and Motohama, my other male friends, running away from a stampede… of angry kendo club girls!

"Get back here you two!"

"Just because Ace is not around doesn't mean you can peek on us!"

""Help us Issei!""

"Aaaaaaaaaaaaaaaaaaaaaahhhhhhhhhhhhhhhh!"

And my first day began with me being trampled under a stampede of girls. At least I managed to catch a few glimpse of their panties before passing out, ufufu.

"Ouch, careful Irina, I'm still in pain."

"Stay still and let me clean them, Ise-kun."

"Ouch."

I, Hyoudou Issei, became a victim of what was known as a stampede of angry girls when I didn't even do anything. To borrow a phrase from a certain bastard protagonist with his own harem…

"Fukou da, ouch!"

"I told you to stay still."

I am currently being treated by my childhood friend Shidou Irina in class. I'm lucky that the girls didn't beat me to death like usual which is probably what would've happened if I were to follow Matsuda and Motohama peeking. Normally, a pervert like me would've been happy being treated by a girl as pretty as Irina but I stay silent and let Irina treat me without thinking anything indecent.

Why is that? This is Shidou Irina, one of the cutest girl in school ranked up there with the twintail trio which makes her one of the top ten girls. Any boys would be happy to be able to get close to her. Well maybe not Vali since he is a maniac who loves fighting more than anything and not Kiba Yuuto since… I don't think he is straight. But as for me, I am just used to her presence. We've been friends for a long time and as much of a pervert as I am, I will never think like that towards someone who I consider family.

Plus anyone knows she is pretty much untouchable. The twintail trio are untouchable since they are crazy but Irina is because of Haruka. Say what you may about him, he even drop a thick encyclopedia on Irina if it means waking her up but he loves his sister and is protective of her. So yes, if anyone wants to bag her, they have to face the ace of the kendo club and will probably be beaten to a pulp first.

Plus I myself won't let my childhood friend be bagged by anyone like me! I swore that I will protect her innocence and together with Haruka we will protect her from unsavory boys!

Putting that matter aside though, I feel bad for making Irina tend to me like this. She's always the one taking care of me, Haruka, and Vali (if Kuroka hadn't already in Vali's case) whenever we're hurt and I'm the one who's frequently using that service since… there is Matsuda, Motohama, and the kendo girls.

What's worse is that I heard that the kendo girls had tried dragging Kiba and Haruka into their changing room once to try and bag either of them! Why is life so unfair! Haruka, trade place with me!

Guh, it seems like my oppai power is in the red. Damn you Haruka for denying me my oppai paradise! If there is one thing I don't like about you and Irina coming back is this! I don't need to be set straight!

"Hello, earth to Ise-kun? You have that lecherous face again."

"Ehh, uhh, sorry about that."

I apologized to Irina. I don't like showing her that side of me. At least that's one thing I need to work on. And why is she fidgeting like she is nervous?

"Ise-kun, are you alright?"

"Hmm? Yes, I don't think it hurts anymore."

"No, not that. It's been two years since then."

"Ohh…"

Now I get why Irina is nervous. Two years ago, I had a girlfriend. We were together for four months and I really love her. Her name was Amano Yuma. She dumped me for another guy. Since then… I guess I'm still affected by it if I did curb my perversity. I haven't gone peeking anywhere for almost two weeks.

Irina was the one who console me back then. I locked myself in my room for days. Funny enough, the reason why I met Vali was because she booted me out of my room after four days and forced me to get some fresh air with Haruka while she clean up my room. She's dependable when you need her and a very good friend. She's so good that I consider it a taboo to peek on her after that.

She's concerned about me.

"Don't worry Irina. I'm already over her."

"Ise-kun."

There's a comfortable silence of mutual understanding between us. It is good to know that there is someone like Irina that I can call my best friend… until that silence is broken by a scream coming from outside the window.

"Dammit Sera! Let me go!"

"Nope! I won't let Haru-chan go until you agree to join our class!"

Both of us look outside to see Haruka being chased by the twintail trio though one of them have dropped out and only Serafall-senpai and Momoka-senpai are chasing him. It's almost a daily spectacle here whenever Haruka encounters the infamous trio.

"They slipped up."

"Yes, they did."

Haruka called Serafall-senpai 'Sera' while Serafall-senpai called him 'Haru-chan'. They didn't do that unless they're at the height of their excitement. Despite everything he said and all his complains about Serafall-senpai, they're actually very close. I can't help but envy him!

The entertainment ended though when the bell rang. Irina and I got back to our respective seats and the first day of school starts.

Class started once the bell rang. Well, not classes really but homeroom. Once the teacher start talking, I feel my eyelids getting heavier and heavier. Halfway through it and I have dozed off or so I believe.

Because I'm sure I'm currently dreaming!

Ufufu, there are boobs, boobs everywhere and they all belong to me!

"Ise-kun."

Huh? Wait, that voice is familiar. I look around trying to find the source of that voice. Then I found it. A perfect set of breasts! It's big but not so big that it looks like a fake and its perkyness… I try touching it and it's just like how I…

*SMACK*

"Owaa!"

I felt pain on my head and eventually return to the real world. I fell off my chair but the pain on my head, I'm sure it's not because I fell and hit my head. It's a familiar feeling. It's like someone hit my head with their fist I look up and there stood Irina whose face is red and her right hand is clenched into a fist looking like she had just hit someone while her left arm is trying to cover her che- Ohh shit!"

"Pervert!"

Oops, looks like in my sleep I just groped Irina. I look around and the class is fortunately almost empty but still, looking at her almost crying expression made me feel bad.

"S-sorry Irina."

"Hmph, even when sleeping you're still a pervert… at least you're thinking about me."

Huh, what was that? I think she said something after calling me a pervert but I can't hear her muttering. I continue trying to apologize to her. It just felt wrong when it's Irina. And it's just earlier that I swear that I will protect her innocence! No! If Haruka knew, he would kill me! Fortunately I remember earlier that he is busy with a new student who wants to join the kendo club… I get the feeling that I also should not mess with that new girl or Haruka will kill me.

"Anyway, what time is it?"

"School is already finished, Ise-kun. You slept through the final period."

Irina told me. Ahh, I see. Thank goodness. That mean not many people saw what I just did and if anyone were to report to her brother… I shudder while thinking what Haruka would do to me. Even Matsuda and Motohama wouldn't dare mess with the famed ace's twin sister.

"Hmm… Ah! I'm late for my club! Sorry Ise-kun, talk to you later, bye bye!"

"Oi Irina, wait!"

Irina, looking at the clock, ran out from the class and went to her club, whatever it is. I was never in a club so I never asked her what her club is. As I got up from the floor, I felt a weight on my back that is sadly not a girl but one of my friends. Not Vali, but a… partner in crime, two of them.

"Get off me Matsuda, Motohama!"

""Issei you damn traitor!""

The two of them yelled at me. They've been calling me that since Irina and Haruka came back, especially since Irina is close to me. I kept telling them that there's nothing special between us. I don't perv on my family dammit! Well, maybe a little since Kuroka is just too damn seductive! Too bad she's already claimed by Vali, not that the bastard would admit it.

"Hohoho, are the virgin duo jealous of Hyoudou-kun since he has a childhood friend to take care of his every needs?"

That voice! Dammit, not her! The most perverted girl in class and the female counterpart of Motohama, Kiryuu Aika!

"What do you want, Kiryuu Aika!"

"We're punishing Issei for his betrayal. Damn him for having one of the top beauties as childhood friend!"

"Maa it's not like anyone but Hyoudou-kun have a chance with her. Remember, there's an insurmountable wall guarding that particular girl."

Kiryuu reminded. Matsuda and Motohama freeze and shuddered, likely remembering what, or who they have to face if they dare try to lay their hands on Irina.

"Damn, it's true that Issei is not the final boss if we want to get to Shidou-chan."

"Indeed, nobody would dare to get close to her as long as the Ace is watching. But!"

The two of them turn towards me, both with fingers pointing. I blinked confusedly at their action.

"Here we have someone who has the blessing of said Ace and even Shidou-chan's care but look what he's doing!"

"I bet this fool doesn't even realize that he already has what many boys in this school want!"

Seriously, what are they talking about? I ignore Matsuda and Motohama and speak with Kiryuu.

"Oi Kiryuu, I was wondering, what is Irina's club anyway?"

"Huh, you mean you didn't know? It's…"

I immediately rushed to Irina's clubroom after hearing what Kiryuu told me. Why did she say she has a club activity? Her club was disbanded last year after all its members except her graduated.

I finally arrived in front of Irina's clubroom, the second music room, the place where Kuoh Academy's Light Music Club used to gather and practice. I was about to open the sliding door when I heard the sound of an instrument. I recognize it as a bass. After some instrumental, I finally heard Irina's voice coming from the clubroom.

'Tasogare kousaten kakeyaru

Aitai to omou sonna kimochi wa'

I was stunned as I hear her voice. I slowly open the door, carefully sliding it as if I don't want to be noticed.

'Sora wo oyoideru kumo mitai ni

Butsukatte, tokete, kieta'

I have never noticed, I have never heard her. Kiryuu said that she performed at last year's cultural festival but I didn't hear her singing. I left before the band performed their last song which was the one that she sung.

'Itsukara darou surechigatteru

Soredemo dokoka de

Anata dake motomete iru'

I opened the door wide and there she is holding a bass and singing at the same time, a Shidou Irina that I had never seen before. The moment I laid eyes on her, something inside me moved.

'Aitakute sora ni egaita

Mirai he to tsu… Ise'kun"

Irina stopped singing when she noticed me, seeing me just standing by the door… captivated.

And that's a wrap! It's a funny thing why I decided to write this one. I was watching 'Fuuka' when I thought "Why the hell not?" and so I decided that Issei x Irina story will be about a light music club. I have lots of materials for this type of story considering I played Da Capo 2 and White Album 2.

Ohh and FYI, the song Irina sings is 'Tasogare Kousaten' which is the song for the first 'Kimi no iru Machi' OVA. I felt it's fitting since I got the idea from 'Fuuka' which is another work by Seo-sensei.
