You mean to tell me that for centuries he hasn't even experience love at all? What about that doll from earlier chapters?
I get that he used a body of a dead pregnant sea turtle, and black hood did stated that Fushi can copulate with other humans.
But the thing is I don't remember Fushi haven't even experience any proper intimacy or skinship. So idk if he is gonna give it a shot with Mizuha (possibly or her descendents) if giving birth is gonna help him experience love.
Ooima what r u doing lmao
