@CerusSerenade: didn't she kill him once though?
Mxy for the win....he broke the fourth wall and entered our world LOL
One can argue featherines library is a collection of universes, each book contains universes, however characters have jumped through books showing connections between books and even storyline....if there were infinite libraries, that would be a different question.
Each book is a Multiverse. The best Myx has ever done is play with a planet, and the best Joker has ever done is "destroy the universe" at will. Bernkastel could litterally play with a multiverse since they've all been turned into books. Bernkastel destroys universes several times at ftl speeds while fighting with Lambdadelta as a side-effect of their fight.
Bernkastel is far stronger.
Can you prove to me that each book is a multiverse and not the library itself...do you know the difference between a megaverse and a multiverse? its seperated through a void or some sort of wall, with neither multiverse havng any connection to one another, clearly the library connects the books, and all the books reside within a library therefore the library is the multiverse itself, and the books are merely accumulation of universes. Worlds funnest had mxy insane feats on panel that owsn anything umineko visually showed. Umineko is exactly like the dark tower, the dark tower has 600 floors, each floor has universes leading to the assumption it was a megaverse/ omniverse but king himself acknowledged it as a multiverse only. The sin megami tensei verse, marvel and dc make clear distinctions in regards to the seperation of multiverses, umineko frankly does not hold up to that.
