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

Even though we just exchanged contact info at school today, why bother calling…?

I think using Ein messages would have been more usual. Fortunately, Kanon-chan was currently in the restroom. Girls usually take a while there, so swiftly attending the call and getting it over with might be a good idea. Plus, it would be awkward to pretend not to know anything after you made the effort to call.

Amidst various conflicting thoughts, I nervously answered the phone.

“Hello?”

[Itsuki-kun… good evening.]

“Go-good evening.”

[…]

“…”

After exchanging greetings, a brief silence fell. Why did she call… this girl?

I can hear breaths like “n…” or “haa…” from the phone, but Kanna never uttered a word.

“Um, Kanna? What’s wrong?”

As it got awkward, I decided to ask from my end.

[I-It’s not a big deal…., but since we exchanged contacts…., as a commemoration…]

“Itsuki-niisama!!!! Please help me!!!! I… I need to go… I need to go!!!!”

Suddenly, Kanon-chan, who was in the restroom, shouted loudly.

“Kanon-chan?! I’m coming now!”

[Huh? Itsuki-kun?! That voice just now…]

“Sorry! Kanna, I’ll call you back later!”

“Hey!”

I hung up and quickly rushed towards the restroom.

Opening the door, I found Kanon-chan trembling, turning pale. Of course, she’s fully dressed.

“Kanon-chan? What’s wrong?”

“…Cooooooo….Coooooooo!!!!…”

“Coooooooo?”

“COOOOOOOOOOOOOOOOOOOOOOCKROACH!!!!!”

Having said that, Kanon-chan pointed at the toilet door with her index finger. Her fingertip was trembling quite a bit…

I put on a surprised expression, tore off some toilet paper, and dealt with the cockroach stuck to the door.

“…”

“Hoo…”

Kanon-chan stared at me curiously. Her transparent blue eyes were just like Keisuke’s.

“Thank you very much. Thanks to you, I was able to safely go inside it.”

“Nah, don’t worry about it. I mean, I think I’m taking measures against bugs, but they occasionally show up…”

After returning to the living room, we settled down while having tea.

My stomach started to growl, and I started feeling good somehow. Being treated to high-class sushi by a middle schooler was a bit much, but I want to cherish the feeling when my actions are rewarded.

From now on, I need to support Keisuke more so he can confidently interact with people other than us.

While thinking about such things and sending a warm gaze to Kanon-chan, she gently put down her teacup, nodded as if determined, then turned towards me and spoke.

“Itsuki-oniisama.”

“Hmm?”

“Is it acceptable for me to call you ‘Master(shishou)’?”

“Huh?! Master!?”

When Kanon-chan said something so unexpected, I almost spat out the tea I was drinking, but I managed to swallow it and asked with my gaze for her to continue. Then, with a confident expression, she straightened her chest and replied.

“Yes. I’ve always heard about you from my brother, but after meeting you in person, I realized there’s still much I need to learn.”

“… “

“I want to protect my brother, but I’m someone who gets weak-kneed even at the sight of a single cockroach. However, being with Itsuki-oniisama, I believe I’ll become stronger and surely be able to protect my oniisama.”

“R-Right…”

She’s truly a good and caring sister. There are no signs of malice or deceit in those round eyes.

Feeling so touched that I almost teared up, I cleared my throat to mask my emotions and replied.

“Understood. If that’s the case, I’ll become your master.”

“Oh… Thank you very much!”

“But you know, just protecting isn’t quite enough.”

“Huh?”

My suggestive words make Kanon-chan tilt her head cutely, looking puzzled.

“I’ll support you so that Keisuke himself can become stronger.”

“!!!!”

With her eyes wide, Kanon-chan stared at me as if drilling a hole, her small mouth slightly ajar, resembling a doll.

Soon returning to herself, Kanon-chan smiled warmly and replied to me.

“Yes! I’ll keep it in mind. Itsuki… Master!”

“Yeah.”

Ignoring such a cute girl and eating alone would definitely invite a curse.

It was late at night, so I intended to escort Kanon-chan directly to her house, but conveniently, my parents arrived home. My father, looking quite worn out like a zombie, entered inside, while my mother, with radiant skin, smiled brightly.

In the end, it was decided that Kanon-chan would be driven to the Shizukawa residence by my mother. Well, I feel relieved if she’s with mom.

After exchanging greetings, I returned from the entrance to the living room and saw my dad, who was sitting on the sofa, looking quite worn out.

He always does his best for Mom and me. Seeing him like that somehow gave me a lump in my throat, a feeling akin to holding back tears.

I went to the kitchen, grabbed the green juice I used to drink a lot before being reincarnated from the fridge, and pressed it against Dad’s cheek.

“Chilly!”

Dad looked at me, surprised.

“Dad, drinking this will make you feel better.”

“Itsuki…”

Dad accepted the green juice from me and promptly drank it without hesitation.

“Whoa… it’s bitter… but it tastes like it’ll make me feel better.”

“Right? I also have garlic extract supplements.”

“Hehe… watching you recently, I’ve started thinking I should take care of my body too.”
