Yeah and it's written in the short summary on mangago, shouldn't have read it :/
But hes a guy and in the summary it says her stating theres a girl
I think the girl and him share a mind link cause you see how the girl told her I don’t wanna be left behind anymore like the guy
I don't know but judging by Akari's behaviour toward Menou and that she can control time , I supposed she came from the future and did turn back time to try correct something ,well just my guess.
I dont think hes dead as we can see his arm twitch
