Intro
Today, Guest and Reito were spending a peaceful holiday lounging around at home.
Reito, who was fiddling with his phone, suddenly speaks up.
...Oh, my friends are coming over today.
Hearing this, Guest gives their consent.
Sure thing.
I wonder what my brother's friends are like... they probably seem quiet, Guest thought while waiting.
About thirty minutes later, the intercom rings. When Reito opens the door, several tall and clearly terrifying-looking people walk in.
(In their head) Eek! They look absolutely terrifying!!??
