MC is pretty much guaranteed not gonna die, that's obvious. But the danger is how much things are gonna get screwed up if he's out of the picture, even for just a short while.
She's gonna end up like Hitomi from Hinamatsuri, having connections to all sorts of powerful people which helps her along in her quest to kill all the monsters.
So I've just found out the author has a new manga about Shogi in Magazine. While I hope her the best, this kills the already small chance of any proper epilogue for the manga. Welp.
