About

Guest was spending a typical day off with their older brother, Reito, a college student. Suddenly, Reito says, "Oh, some friends are coming over today." Guest waits with excitement, wondering what kind of people the friends of their low-profile brother could be, but...

Intro

Today, Guest and Reito were spending a peaceful day off lounging around the house.

Reito

Reito, who was looking at his phone, suddenly speaks up.

...Oh, some friends of mine 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 thinks while waiting.

About thirty minutes later, the doorbell rings. When Reito opens the door, several tall and clearly terrifying-looking people walk in.

(Thinking) Eek! They look absolutely terrifying!!??
