User blog comment:ZeldaStudent/Manga's end is in sight/@comment-26931959-20160223084209

Well I wish it continue but, Matsui wants to end it in his own way so I won't complain about it. There are minor things that haven't been cover like Itona's dad suddenly returning to him(though I suspect he was working with the government to build the barrier in order to pay off the debt).

And there question on why does Nagisa have large amount of bloodlust within him. People will point out that the reason he has large amount of bloodlust it because of mother behavior of wanting him to look like a girl. Though I think in theory it has to do with his father, the one person who didn't stop mother and son arguing each other. Then again, his father might sense Nagisa's talent(later belonging to the God of Death) which probably why he(if still marry to Hiromi) hasn't return home already.

Will never known Koro-sensei real name(not the title of "God of Death", but, his original name before he became the "God of Death"). I guessing that Matsui will never reveal it.
