1 Work in The Caligula Effect (Video Game)
27 Apr 2018
Izuku was thirteen when he entered Mobius and fourteen when he escaped with the Going-Home Club.
Mobius was closed down in response to their escape while Aria and μ regained their freedom.
(Or, a Caligula crossover in which Izuku entered Mobius when the bullying got too much and joined the Going Home Club.)
