It is, but the way the story is headed, it's probably not FF
It probably depends on whether you think them being sold en masse by a mohawk implies abyuse for the ko in the future. While mohawk has long been a shorthand for abyuser, same as industrial production of yukkuri, the buyers look pretty normal, and the package seems too comfortable for abyuse-use yukkuri, so... I guess it's pretty ambiguous. It's probably better to keep it tagged non_violent but not FF, I think.
Isn't it against the rules to make violent comments on non-violent posts?
Someone correct me if I'm wrong.
Only those with the family_friendly tag. There are a lot of non_violent posts that are actually part of an abyuse series. This one seems to be pretty tame, but as said by Newbice, the story might not be FF in the end.
