- Kumagawa is composite Manga and Anime
- Yhwach has Manga and Novel feats (apparently he got some good context behind a lot of his abilities in the novels so there you have it).
- Kumagawa is EOS, he has All Fiction, Hundred Gauntlets and Bookmaker.
- Yhwach is EOS and has the schrifts, all sternritters abilities, Yama's Bankai, The Almighty and whatever else I've missed.
- Stats unequal
- Both are in character
- Win by permanent death for each side, each opponent must be able to put each other down for good with no chance of resurrection. Infinite death loops or sealing are fine too.
It's All Fiction vs The Almighty, who wins?
