My Hero Academia has reached an unexpected new level as the fight between Izuku Midoriya and Tomura Shigaraki has forced their respective One For All quirks to coalesce and clash to the point that there was an unexpected reunion between Nana Shimura and All For One. With Deku completely diving into his rage as the fight with Shigaraki grew more intense over the last couple of chapters, both he and Shigaraki have reached new levels of mastery with their respective inherited quirks. But this also means that each of their previous users have made an appearance all at the same time.
