@Drailis I agree with that statement there. as far as i can tell the oni don't do that and to the momotaros the oni are just bad for just existing. Then when the oni retaliate for the momotaros killing their families the oni gets blamed as evil for fighting back.
I guess that's it and either wait for them to settle down and pick it back up or have another group pick it up like others. It is kind of sad to see the groups fight for manga like this it is not that enjoyable seeing this happen for I don't know how many time on this website.
