Ah yes, the UA Civil War Game. Nezu's brilliant idea of fun. Basically, real-life Among Us with real heroes, hero students, and cameras broadcasting your every move. The idea is that while the audience figures out who the secret villain is through the cameras, the heroes have to figure out who it is before the villain eliminates them all. Not by actually killing them, of course. Nezu may be a mastermind, but not an EVIL mastermind. Not yet, anyways.
And with the mastermindedness he has, he's also picked up on some things. Take the hero student Izuku Midoriya, for example. Strong, kind-hearted, slightly nerdy. Always writing in those notebooks of his. But when Nezu glances at one of those pages, he sees something that could be have... potential.
Long story short, there's a Civil War Game with 44 heroes and one villain. And with the villain, it surely doesn't FEEL like a game.
