Ugh I love AIB. Haven't seen season 3 yet but maybe one day. I love/hate Niragi, but adore the actor who plays him. I hate him cause of what he did to Usagi but I also feel like his villain arc is deserved because of what happened to him in high school.
In AIB Season 3, Niragi survives the games, chooses to return to the real world, and begins a journey of redemption, working to become a better person and find purpose, showing that even the most depraved individuals can change, a theme reflecting Arisu's own belief in saving everyone. He undergoes severe physical trauma but endures, ultimately deciding to change his ways, contrasting his past villainy with a future focused on self-improvement, symbolised by him working hard for "his kid," which hints at a positive, albeit ambiguous, future path.
