My only issue is that Akuta showed up in that one chapter and was like "Time to save the day" and then never shows up again. Bruh.
No idea who their father is (cant possibly be kii or his son and why did he have those powers and who took them away?).
You can tell that the ending was kinda rushed but at least it was somewhat satisfying.
Also Rina just remained as Shizukume's sister doppelganger because this is technically the aftermath of the original destroyed world after Ichi fixed it.
Too much stuff was skipped, but the author is running out of chapters and this is the best he could do, so.. Ok, I guess..
Here's what (I think) happens between ch.138 and ch.139:
Go back to the exploding planet, stop time, fix the planet, revive everyone (that MC cares about), and alter their memories. Everything is still happening in that universe (all the misfortunes, magic sticks, and all. Aya didn't change the history in the OG universe, only fixing the future) that's why Shioi still uses Sarina's sister's appearance, and everyone knows each other in the end page. (the Aya in the other universe barely has any friends)
But why does Aya need a time freeze stick if Ichi could do it? (Nana said Ichi has the power of all sticks in ch.128) For plot I guess..
What happens to other Ayas? Ichi sends them back to their universe (but their universe still has King & Ichi and they could be plotting something else?)
