"Eh!?" (Rein)

"Don't 'Eh' me, you stupid brother!! Do you know what time is it !?? It is 5 in the morning!!"

"Uhh, yeah.. I'm sorry.."(Rein)

Hmm... By the way she called me, She is supposed to be my little sister..

Her name is ...

...

Dang, I also forget her name!!

Won't she become suspicious if i don't know it !?

Wait, why must i be careful about it?

She won't hurt me, right?

She is not the kidnapper, right??

She is not an alien that disguise as my sister, right???

....Right, let's not be negative..

My common sense tells me that it's impossible to become like that.

Let's believe in my common sense.

So, her name...

For the sake of simplicity, let's call her sister(temp).

....Yes, Let's examine my little sister(temp)...

She has aura of "Tsundere"[1].

She has same hair color like me. Her ponytail hair quite long and fluffy.

Her eyes' color are surprising blue.

She is quite cute and beautiful in my opinion. Enough to be a model...

I assume most of guys want to date her.

Eh? Me? Of course not~

Don't be joking!?

She is my sister (temp) right?

Eh? What if she is not blood related you say?

...No comment for that..

Hmm the more i look at her, isn't she more protagonist than me?

Good appearance, special characteristic which is her unusual eyes' color.

Don't tell me that i'm just my litter sister's supporting character!?

"Hey Big Brother, Why don't you say anything but keep staring at me while making stupid face??" (Little Sister(Temp))

"Umm, Good moring my sister(temp)?" (Rein)

"Why in question tone!? and What is sister(temp) !?? Are you stupid !?" (Little Sister(Temp))

"Well, my sister(temp)... Indeed I'm stupid for now... You won't believe me, but let me tell you this.... I get amnesia!! " (Rein)

*smug face*

"What's with that SMUG Face!? Don't be joking,stupid !!

Did you hit your head!? Has you brain gone rotten !?" (Little Sister(Temp))

"Hey, Calm down my litter sister(temp)~ , I'm serious you know...

I currently remember nothing about everything related to my identity. That's including your name."(Rein)

".... "(Little Sister(Temp))

"...." (Rein)

"Haaah... Okay then i try to believe you..." (Little Sister(Temp))

"Thank you my little sister~~ For now, May i know your name??" (Rein)

"Hmpt.. My name is Rinne.... Don't you dare ever forget again! I will hate you If you forget!!" (Rinne)

"Thank you Rinne..."

*pat her head*
