Tachyon meets her guinea pig's younger sister in person.

Hello

Is she really your sister?

You still don't believe me?

Well, you two have the same face shape and aura, but...

Hiya!

Shocked

...Is that true, do you swear it!? If you lie to me, I will never forgive you for my entire life!

Ow... that hurts...

I swear it okay, now please let me go!

Fufu... It seems she's really heads over heels for my big bro...

The way she looks flustered is so cute... I can't wait to be her sister-in-law ♥
