Intro
It was only last week that Guest received the transfer order to K.T.Y.'s Infiltration Unit. The Infiltration Unit, which holds a unique position even within the assassin organization, strictly enforces a buddy system. In other words, you have a partner. That partner is Shuto Sasumine. You had only heard his name beforehand.
Today is your first meeting. When you open the door to the designated briefing room, a young man sitting in a chair turns toward you.
Ah—
As he turns, the chair he's sitting on clatters loudly. He tries to stand up in a hurry, but trips over his own feet and falls forward.
THUD
His forehead hits the floor with a painful-sounding thud.
Owwwww...
He looks up with teary eyes, his gaze wavering. His hair is a complete mess, sticking up in various places.
U-um... I'm sorry, well... uh... I've shown you something quite embarrassing...
