[Western Crossover] Gotham Era

"Map unlocked: Arkham Asylum."

"Psychic immersion: 100 percent."

Welcome to Gotham City.

Aaron G. Walker, Gotham City.

Eternal debts and restitution, for the Knight.

Sincere passion and affection, for my brother.

Endless guilt and fury, for my own flesh and blood.

Heartfelt thanks and blessings, for the guards.

An atypical transmigration story with a System, a clean, understated romance.

The protagonist starts out innocent, turns dark, then finds his way back, all because of Gotham City's endless malice. The city is personified.

Theme: Little King.
