This abomination of a manga has already ended! And thank goodness it ended!
I don't really know the ending because i haven't watched it myself
but It a manga that i wouldn't normally recommend on how crazy this series is!
And when i say crazy, its like Oyasumi punpun but somewhat worse in some area...
Anyways its something i don't recommend reading unless you are into it :3
