Aisaka Tatsuo wants answers

Aisaka Tatsuo wants answers

[Aisaka Tatsuo! The affectionate younger sister of Shirou Tatsuo! Aisaka Tatsuo is a second year at Shuchiin Middle School and the Student Council President! Just like her older brother, Aisaka Tatsuo is considered to be a 'True Prodigy' and can master almost anything in a short amount of time. Because of this she is the top of her grade and is enemies with Kei Shirogane but that's not important.]

[Lately, her older brother has been spending more of his time with a female student in his school. Since this is cutting the time with her brother she decided to take this into her own hands now that her brother got a cold from the same girl...]

Aisaka's POV

Before I left for school I managed to get some information about the girl Onii-Chan has been with lately. All I know is that she has blond hair, Irish and her name is Ai Hayasaka. That's not much to work with though but if it's for Onii-Chan then I'll do it! After school I began my search to find whoever has been seducing my brother. After failing about five times in a row I saw another prospective student that fit the bill.

Not to mention she definitely has my Onii-chan's preferred body. If she's not the one, I don't know who is. I walked up to her and asked, "Can I speak with you outside?" She looked at her friends for approval. They shrugged their shoulders which gave her the permission to leave. Immediately when we were outside she asked me, "Who are you and what do you want from me?" That was quite rude. I came all the way here just to be talked rudely at.

"My name is Aisaka Tatsuo, the Student Council President of Shuchiin Middle School, I suppose." She looked puzzled like she heard that name before. Onii-Chan probably told her all about me and how loving and sweet I am. That's when she finally put her finger on it and exclaimed, "You're Tatsuo-kun's little sister!!!" Took you long enough to connect the dots that aren't even hard to connect. She looked wary of me as she should be.

"That's right! I'm the sister of the poor boy you've been seducing, I suppose!! Now that I look at you I understand how you've been seducing him! You're using your boobs against him!!"

"He always had that fetish..." I mumbled to myself. I know mine are already a d-cup but... Hers somehow look bigger than mine!

"I haven't been seducing Tatsuo-kun! We're just friends!!!" She said, defending herself.

"Sure. Whatever you say... just 'friends'. I heard what you did to my brother the other day! If it wasn't for his... 'self-control' this would have escalated way further than it already has, I suppose!!" That statement seemed to move her. She seems scared that someone else had known what she almost did to my brother. Finally she asked me in a wary tone, "I-if I tell you the root of my connection with Tatsuo-kun would you let me go off the hook?" Now she's begging for mercy as she should be.

I could've called the cops that she attempted to rape my brother and she would've been old news. Since I'm nice I'll hear her out. "I'll make my decision after you tell me. I can't make any promises." She sighed as she began the story, "I met Tatsuo-kun about ten years ago. My life had been switched upside down and I didn't know what was good or evil anymore. Tatsuo-kun saw me and even though he did had the slightest idea who I was he still helped me."

I didn't know my brother was a simp. She continued, "Tatsuo-kun gave me a helping hand even though he didn't know me and... I might have fallen for him right there and then..."

"So... you like my brother?" She blushed slightly whenever I said the statement.

"Is... is this the whole truth?" I asked her. She nodded. Lies.

"You're lying! I heard the whole story when my brother was hallucinating!"

"You used Tatsuo-kun's hallucination when he was the weakest to get the truth out of him?"

"It was for a noble cause! Anyways, I know exactly what's going on between the two of you! You're trying to make the other one confess to each other!!"

"Was there any point in you coming here?"

"I came to see if you're worthy of becoming my brother's bride, I suppose, and I have made my decision..." I paused for a moment creating a dramatic effect.

"You passed the trial and I know exactly how you can make Onii-chan fall for you." Hayasaka looked shocked as I finished my sentence. "You're going to help me?!"

"Why wouldn't I? You clearly care for my brother deeply I suppose. Besides, our names are compatible."

"N-no I don't!" She stuttered.

"By stuttering you proved my point even further. Whenever I first said my brother's name your heart rate went up. You tried to calm yourself by doing some kind of ritual which then made it beat regularly once again. Do you want me to continue?" She shakes her head meaning no and then she asked, "What am I supposed to call you?" I smiled and answered, "You can call me Ai."

The winner of this battle: Aisaka!
