A dark Tokyo Revengers Bonten-era AU exploring obsessive, toxic, and psychologically complex relationships between the members of Bonten and a girl named Mussa, where love becomes control, dependency, and emotional manipulation within a dangerous criminal underworld.
Mussa is accidentally added to a secret Blue Lock group chat monitored by Ego as a psychological experiment. Players are secretly competing in both matches and chat, where ego and dominance are tracked. She thinks it’s just chaotic Gen Z texting. They think she’s an “error variable.” Over time, her normal, casual presence disrupts them—brutal ego rivals turn soft in chat, and one by one, they start getting attached to her without admitting it.
