Yeah, I realize the whole Yamanaka/Ino vs actual literal boars of the Princess Mononoke film might get a little confusing… um.
As adorable as literal boar piglet!Ino would be, she is human in the Reasons To Keep Living ‘verse, so… sorry to rain on your parade, anon.
There might be a boar piglet which is familiarly sassy which “the stranger” decides to call Ino, but that’s probably as close as I can get.
