So, do i get this right?
- They travel back, erase Hiruko aka Shadow-Mommy aka the whale, so the whole stuff with shadows never happens.
- Ushio travels to the point where Shinpei comes back to the island, leading to the moment from the first chapter where she gives him that eye and the memories of all that happened.
- Since there where no shadows, Hizuras brother still lives and apperantly somehow Haine (the girl Hiruko/Shadow-Mommy copied) was reincarnated as his daughter.
- And since Ushio also had this "dream", it seems Shadow-Ushio also gave her (normal Ushio) her (Shawod-Ushio) memories, hence that "moment of recognition" during the firework.
Is that all, or did i miss something? If thats all, and i am not wrong, that still leaves 3 plotholes:
- The usual "timetravel-problem". If the whole thing never happened, there wouldnt have been memories to transfer, no one to go back to erase Shadow-Mommy, therefor it would still have happened, and so on. And if we got with the "its was parralel / possible timelines" argument, that means in the end the whole thing was pointless since we are left with an infinite ammount of universes / timelines where the shadows win, and an infinite ammount of universes / timelines where the whole shadow thing never happens and they get a happy-end.
- Shinpei originally came back because of Ushios funeral, but since she didnt die, she called him, making him come back anyway, so no problem there. But why is Hizura still going there? In the last chapter we get a glimps of how she receives the message that made her come back to the island in the original timeline. But since the whole stuff with shadows never happens after erasing Shadow-Mommy, that message shouldnt have made any sense to her. Not to mention that, if i remember correct, it was Shinpei that left her that message in the original timeline, not Ushio.
- The "welcome back" at the end kinda bugs me. That kinda makes it look like this is supposed to be Shadow-Ushio, welcoming him back. Remember, Normal-Ushio only got the memories and remembers it as a form of weird dream, so that "welcome back" seems of. But she also cant be just Shadow-Ushio since that would mean the somehow overwrote Normal-Ushios character, which would mean Normal-Ushio still died in some kinda sense (at least i would say someone "dies" when his personality gets overwritten / replaced). So is that Ushio at the end supposed to be a combination of both Ushios?
I know, at the end its always best to not overthink things when timetravel is involved. But i really like to nitpick!
