Family:
Father - Shihai Takeyama - Age 40's
Mother - Saikō Takeyama - Age 40's
Sister - Yu Takeyama - Age 22

Personality:
Otoru are a more distant person, the kind of kid who prefers to sit in the background and stay out of the spotlight. He doesn't mind attention but his older sister Yu is a glory hog so he's grown used to staying out of her way. That being said, Otoru can be rather smug when he's praised, a personality trait held by his entire family, which can drive him to avoid being seen as lesser in anyway (making him easy to manipulate at times).
Because of his underwhelming quirk, Otoru don't see himself becoming a hero which is a source of tension between him and Yu. He can't help but be jealous of his older sister for having both a powerful quirk and graduating from Japan's top hero school. Between this and her attitude, the two of them often argue a lot and have a hard time getting along.
While he don't consider himself a pervert, puberty is hitting Otoru hard and it's hard to not appreciate the female body when his sister is both extremely attractive and shameless about it.


Otoru glared at his only friend, Honda. The both of them are alone in a janitor's closet at school, brought here by Honda during lunch period. He wasn't always the nicest person but Otoru didn't have many people he liked to hang out with and Honda was the only one who bothered to spend time with him.

Otoru put a hand through his blonde hair, "What do you need that's so private, dude? I'm starving."

Honda put on a smirk and reached into his pocket, pulling out his smartphone and scrolling through it. Otoru raised an eyebrow at him until Honda shoved the phone in his friend's face, "Does this look familiar to you, Takeyama?"

The light of the small screen blinded Otoru a bit so he had to squint. Upon seeing some familiar text displayed, his eyes widened, "Uh...what's that?"

He laughed, "C'mon, you don't think I recognize your dumb username? I was just scrolling through some stuff when I suddenly come across some spicy fanfiction about Mirko. And imagine my surprise when I see who wrote it."

Damn it, this was embarrassing. Otoru wasn't the best writer but fanfics were a good way for him to let out some of his overactive imagination onto the page (or screen). And with all of these damn hormones from puberty, some pro heroes started looking so much more...enticing. He took these pent up hormones and put them into some writing, and Otoru just had to post them.

He sighed, "Damn it..." Honda, while claiming to be a friend, had a habit of making people do him favors. He'd find something that embarrasses somebody and then tease them into helping him out with some task. He'd done this to Otoru a few times before, but not with anything like this. "What do you need, Honda? Doing your homework again? Paying for your lunches?"

He shook his head and put a hand on Otoru's shoulder, "C'mon now, Takeyama. This is waaaay too juicy for something basic like that. I want something a little more 'on-theme', if you catch my drift?"

"You...want me to write some fanfiction for you?"

Honda snickered, "Oh no, I want some of the real deal. Your sister is that new hero going around, Mount Lady right?"

Otoru hesitantly nodded, not liking where this was going, "...yeah?"

"How about this, I won't spread around that you wrote this smut and you give me some exclusive photos?"

His jaw dropped, "Wha-Wha-Wha-...?!"

Honda smirked and whispered, "I want to see those big ol' tits. No bra or anything."

A heavy blush overtook Otoru's face at the mental image, "How the hell am I supposed to do that!?"

Honda shrugged, "Do it in her sleep or something? Maybe she sleeps in the nude, or maybe you'll have to take some personal touches to get the photo."

"That's...You're-...!"

"That's not all though." He held up the phone, "I won't tell anybody about your gross writing, but I'm still gonna keep this info for future use...unless you add a little extra to the image."

"What could you possibly want more of!?"

Honda put a hand on Otoru's shoulder, "I can jack it to a pair of tits just fine. But personally, I have a thing for seeing girls all dirty. So if you want to never hear me talk about this again," He smirked and got a dark glint in his eye. "After taking some of those photos, I want you to jack off and cum on that sis of yours."
