Nana is sent to a remote island school for superpowered teens with a secret mission: kill them all. Like Menou, she's an unpowered assassin targeting 'monsters' who think they are heroes.
Why it's similar: This is the closest match because it mirrors the 'assassin vs. overpowered students' premise perfectly. Both protagonists must use deception and strategy to kill targets who possess world-breaking abilities they don't yet understand.
Power comparison: Nana relies entirely on wits and traps against god-like powers, whereas Menou uses her own specialized magic to counter the Lost Ones.
Why watch after The Executioner And Her Way Of Life: Watch this immediately if you enjoyed the 'mission-first' mindset and the tension of a killer hiding in plain sight.
