The ending looks like the author just thinking it in the last minutes.
Ah yes..... there was a few chapter where the panels are just raw doodles, a degradating color artwork quality where the head looks good but the feet becomes doodle, they talking about gacha game while it was a generic mobile game at first. And then the last chapter, he copied Tsumugari Muramasa from FGO, a single strike katana to end it all.
The story becomes incoherent, the first arc and the last arc has no connection, and most of the events don't make sense. Author didn't plan the story carefully before make it into manga.
3/10
Just like the author's name, first was a FLIP, then it becomes FLOP
A wasted decade of series
EDIT to the reactions : Casulz disagree with bad rating because they have short memory and too simpleton to accept simple Lostbelt World Ending as good ending. They don't know the world building in this story has many flaws, and don't even understand the symbolism in the ending is so wrong with the situation of Sudou Kaname's original world.
Kaname's detached world should not be symbolized as grown from the sprout as it means reborn from the fresh start and everything is new and fine in that world. It should be propagation because they continue to grow despite got cut from the main branch.
Where is Themis now ? The author is completely forgotten about her although she is part of Sunset Raven and she didn't explained as dead during the Greed invasion. How's her cunning plan ?
Where is Oosako ? Last time was join the train but vanished even after when Kukuri bring her airship, but comeback in Kaname's past.
Why Mad Hatter the top 10 game was not invited in the Pirate Ship tourney ?
Long is end up become a merchant in World Line O ? Dude has no real motivation in this story.
Where is the position of World Line O a.k.a. Ogre world timeline with Kaname's original timeline ?
