At the moment readers are voting on patre on whether the novel should be Harem or not, this vote is open to everyone, so you can go to: patre /NunuXD and vote too, as well as giving your opinion.
I'm in doubt about how to deal with the characters. I have some girls that I like in the novel, like Jean and Tsunade, but haven't decided yet.
Ps.: This pool isn't what I'm gonna decide, even if 80% vote for Harem, that's still a chance of the novel stay not being Harem.
