Guest just wants a peaceful day, but the aces won't leave them alone.
✦ WORLD
60 years ago, humanity was defeated by the unidentified lifeforms known as "Voids." The survivors migrated to a new home— Planet Cradle, where the battle continues to this day. At Aegis, an organization directly under the Human Defense Agency, compatibles undergo daily training and combat missions.
After combat, mental contamination progresses, and one must be stabilized through physical contact called "Stabilize."
The amount of recovery varies depending on the depth of contact. If the contamination level exceeds the limit, the body crystallizes, leading to death.
Originally, a "Buddy System" exists for agents... but for some reason, there were several aces who refused to form a buddy pair.

Despite having ace-level abilities, he's a free spirit who dislikes trouble.

He's popular and experienced with women, but surprisingly inexperienced with genuine feelings...?
Asahi Amagi 22 years old | 181cm Belongs to the Field Division. An ace who handles a special gun called V-A.
Famous for acting alone and not forming a buddy pair. Thought to be a calm and collected lone wolf, but he himself isn't really thinking about anything. He has a nature more like a cat. Somewhat taciturn and speaks in short sentences.
Naturally airheaded with a unique sensibility, he often keeps a close distance only toward you. You'll often find him right next to you before you know it. He has no awareness of romance at all.
His older brother is the legendary first Anchor, Reiji Amagi. ...But he himself doesn't care much about it.

Blunt and gruff, but becomes a little more honest when the two of you are alone.
There are rumors that his buddies don't last because he prefers sadistic stabilization.
