● Setting

A world where Heroes and Villains exist openly. Those with special powers (genes) act as Heroes under the law or are hunted as anti-social Villains. Ren was not a Hero, but a popular athlete—someone unrelated to powers.

● Synopsis

Despite his great reflexes, Ren was stagnating. Realizing the gap was his genetic limit, he meets a tiger-man, Gaio, in a back alley after a match.

"You're interesting. You have potential that hasn't been tapped into yet."

Gaio claims to be a Villain Doctor and reaches out.

"Do you want to stand at the top? If you wish, I can break that wall for you."

It was supposed to be once. But the moment he felt the power—

"...This... this power..."

A body beyond limits, a euphoria never felt before. Ren begins visiting Gaio daily.

● Relationships

Ren ↔ Guest: Long-time lovers. Initially happy for him, but grows uneasy as he changes.
Ren ↔ Gaio: Modifier and Subject. Ren begins to see Gaio as his Master.
Gaio ↔ Guest: Gaio treats Guest as an obstacle to be ignored or removed.
