I Was Reincarnated as a Creepy Fat Guy, Then Trained Myself Without Sleep. And Then, for Some Reason, the Heroines Start Approaching Me

“You waited for me?”

“Yes.”

“Why?”

“I wanted to repay the favor…”

“Favor?”

Whether it’s Kanon or Keisuke’s sister, they all seem to like the word ‘favor’ in this world of girls.

As I looked puzzled and tilted my head, Keisuke’s sister, dressed in a beautiful dress, with her translucent blue eyes shining, spoke.

“You’re the person who saved my brother… So today, I’ll work hard to serve you.”

“S-serve!?”

Even though I was just served by a playful maid with big breasts yesterday, now it’s the cute sister of a friend offering to serve me…

Sitting on the living room sofa, looking up at me, is Shizukawa Keisuke’s sister, Shizukawa Kanon-chan. She’s a third-year middle school student who wanted to treat me because her brother’s social anxiety had improved, so she came to my house. I think if she wanted to treat me, she should have invited me over rather than coming here, but let’s not dwell on the details.

We didn’t talk during the barbecue party. So, I thought she was shy, just like her brother. But it’s quite bold of her to come to my house alone. The use of “sama” is a bit strange, but I’ll let it slide since she’s showing kindness. I let her in.

But seriously, Keisuke’s way of saying I’ll be cursed if I buy dinner is too much.

“Um… Itsuki Onii-sama, is there anything you want to eat? I’ll pay for it.”

I don’t think that’s something a third-year middle schooler should say… Her voice is really good, though. It resonates strangely in my head.

“No, I’ll treat you. Is there something you’d like to eat, Kanon-chan? Sushi is good too.”

“No, I want you to enjoy something with the money I earned.”

“…”

Even though she looked young, she seemed to emit an aura that you can’t argue with.

So, I nodded and accepted her offer.

We ordered some really expensive sushi and enjoyed it at home. Cheaper ones would have been fine, but Kanon-chan insisted on getting the best quality, so here we are.

“It was delicious. It’s the first time I’ve had such tasty sushi.”

“I’m glad you enjoyed it.”

As I looked at the empty containers, I let out a satisfied sigh.

After drinking her tea, Kanon-chan turned to me with a serious expression.

“Once again, thank you very much. Thanks to you, I can talk to Onii-sama like I used to.”

“Y-yeah… That’s good.”

“I was worried… for a long time… but I am really…r-really glad.”

“K-Kanon-chan!?”

Kanon-chan’s eyes welled up, and she wiped her eyes with her slender fingers. She must have gone through something difficult to cry like this, even though she’s so young.

“Keisuke wasn’t socially anxious before, right?”

“Yes… that’s correct.”

“What happened? Ah, you don’t have to say if you don’t want to.”

“…No. I came here to repay you, but also to tell you about my brother’s past.”

“Keisuke’s past…”

Kanon-chan told me why Keisuke became socially anxious.

Kanon-chan has a beautiful voice. Apparently, her talent as a voice actor was recognized from an early age, and she received numerous scouts mainly from the anime industry. Then, five years ago, when she and her mother came with Keisuke to audition for a famous anime voice acting audition, an incident occurred.

Middle-aged men who had inappropriate feelings towards Kanon-chan sneaked into the audition venue and took her to a dark room, touching her.

Just when things were about to go too far, Keisuke, who noticed something was wrong, came and fought off those men. They brutally beat Keisuke, causing physical and mental damage that would never disappear. Thanks to Keisuke buying time, security arrived and saved Kanon-chan before anything worse happened. However, since then, Keisuke has been suffering from severe social anxiety and has been unable to make friends properly, staying holed up at home.

But meeting me when I was a fat slob seemed to have made him start going to school, and after about a month of solid training, he gained confidence and can now talk somewhat with his sister and parents.

“I see… He had such a past…”

“So from now on… Please take care of Onii-sama..”

Kanon-chan bowed her head anxiously. She’s a wonderful sister who cares so much for her brother.

Seeing her so earnest, I couldn’t help but pat her on the head.

“Nyaa…”

My hands are quite big. And rough. But Kanon-chan, like a little kitten, closed her eyes without refusing my hand.

“If those jerks try anything awful to Keisuke again, I’ll give them a proper beating, so don’t worry.”

“That’s… very reassuring… but…”

“Hmm?”

For some reason, I felt something dark overflowing from Kanon-chan’s head, so I stopped and looked at her face.

Then, her eyes, completely devoid of color, turned to me and she spoke.

“If anyone does anything awful to Onii-sama, I’ll dispose of those trash myself.”

“Huh!”

T-That’s scary! What’s with this yandere!? I got goosebumps for a moment. This aura is not like a middle schooler’s…

As I tensed up and took a step back, Kanon-chan lowered her head apologetically.

“I’m sorry. When it comes to him… I just…”

“Y-yeah… With such a past…”

Kanon-chan raised her head and looked up at me again.

What’s with this contrast… so cute…

Her slightly flushed cheeks, round eyes, and still immature but well-balanced body. She keeps moving her legs shyly, but that’s also cute.

Her legs?

“Um… I want to use the bathroom.”

“Ah, I see. If it’s the bathroom, go out of the living room and turn left.”

“Thank you… Then…”

Kanon-chan got off the sofa and left the living room with graceful steps.

But seriously, a voice actor… If there’s an anime with characters voiced by her, I’d definitely want to watch it. I’ll ask later. Why do I feel like the instinct of the old Kondo Itsuki is roaring within me?

And as I let out a short breath, my phone beeped in my pocket. It seems someone is calling me.

I took out my phone and glanced at the screen, seeing a familiar name.

[Kanna Kanzaki.]
