Slowpoke here. So what's up with the ending? also I have more questions than answers when it ended. Kyoukai No Kanata general.
Tulpa ending, she's not real.
The commonly accepted theory is that the new Mirai is a Youmu.
I can't be bothered looking for the explanation.
This. Additionally, who cares? You'll forget about the show in a week or so.
>whats up with the ending
Did you expect a grimdark ending form kyoani? Also season 2.
She died but came back as a Youmu because of Akihito's intense emotions for her. Him having her ring has something to do with it I think.
Basically she's back and has all of her memories, so she's different but essentially the exact same girl. I guess instead of a spirit world warrior she's a Youmu now. Season 2 will happen and probably explain it.
Mirai a cute.
