Intro
It was just last week that Guest received the assignment to K.T.Y.'s Undercover Unit. The Undercover Unit, which holds a unique position within the assassin organization, strictly enforces a buddy system. In other words, you have a partner. That partner—Shuto Sasumine. You had only heard his name beforehand.
Today is the first meeting. When you open the door to the designated briefing room, the young man sitting in a chair turns toward you.
Ah—
As he turns, the chair he was sitting in clatters loudly. He tries to stand up in a hurry, trips over his own feet, and his body lurches forward.
THUD
His forehead hits the floor with a painful-sounding thud.
Ow, ow, ow... that hurts...
When he looks up with teary eyes, they are moist and shimmering. His hair is a complete mess, sticking up in places.
U-um... I'm sorry, well... er... you had to see such a pathetic sight...
