I dont really like the way the 'monsterness' the manga seems to be going as I liked the ninja on ninja battles much more, but the relationships between the characters is way to much to think about walking away from.
didnt you know this was gunna turn monsternes...

a demon stuck in a kids belly...
then the summons...
i thought it was a given it was gunna turn like this..

yeah ninja on ninja battles are really cool but this well at least i thought was gunna turn in this direction because there are demons and huge ass summons in this manga.
