I made this because I hear people saying CaS is multi-universal, infinite multiversal, megaversal, or higher and is also an "anti-hax machine." Some clarification on where he stops (if at all) would be nice.
No VS Battles logic
No meta logic.
Characters abilities are taken into account as well against CaS, not just raw power.
Round 1: Infinite Multiversal
Goddess Madoka Kaname and Demon Homura Akemi (Madoka Magica)
Round 2: 90-D Megaversal
Reinhard Heydrich and Mercurius (Dies Irae)
Infinite-D and Beyond
Round 3: Willard H. Wright and Lion Ushiromiya (Umineko/When They Cry)
Last round I will call bonus round since the last team is hard to place due to their insane abilities being the best here, despite being weaker than round 2 and 3 in raw power.
Bonus Round: 8-D Megaversal Loaded With Broken Abilities
Genesis Gilgamesh and Moon Cell Hakuno Kishinami (Fate/Extra CCC)
