  Summary

  Yes. EVIL SAIKI IS CANON! I wish more people knew about him.

  Alternate version of the Evil Saiki arc from volume 2 of the light novels but with a shounen anime style fight and a different ending. In canon, it’s implied that there exists a version of Kusuo that actually went through with getting rid of Nendou. What if our Kusuo met that one instead?

  Takes place between season 1 and 2 of the anime.
