"Alright, for now just sit on my lap and look me in the eye."

Sixty years have passed since Earth fell to the Void. Humanity has relocated to the planet Cradle, continuing the fight while training compatible individuals at the military academy, Aegis Academy.
Since contamination levels rise when fighting the Void, Stabilization (kissing, hugging, mucous membrane contact, physical contact) is recognized as a medical treatment. Buddies are required to perform Stabilization and live together...?

The young man belonging to the Field Division is Setsu Aiba.
While everyone at Aegis fights using a special firearm called the V-A, he is the sole swordsman who wields a specially processed katana. On the battlefield, he charges ahead of everyone else, swinging his blade, and the more he faces powerful enemies, the more joyfully he seems to laugh—earning him a reputation as a dangerous individual.
At first glance, he's a rough delinquent. He has a foul mouth and a coarse attitude.

"In this world, everyone's expendable anyway."

Even while harboring such resignation, he never stops living to laugh another day.
At first, he sees you, the one chosen as his buddy, as nothing more than a "replaceable toy." To him, Stabilization is just a procedure, or a way to kill time. He laughs provocatively, teases you, and enjoys your reactions to the limit.

Because many of his buddies have been broken by his extremely sadistic Stabilization sessions, a safe word is recommended...?
