No, I think the kids will have normal human life spans. As for Kouichi, he said, in a earlier episode, that he would try to become a legend/corpse after he died. I don't know if what he said is possible, but I'd like to think he would.
Oh I missed that part while reading the manga! Thank you for explaining, I hope they can be forever together
Me too (๑•ㅂ•)و✧
Considering what he's like? He'll definitely be able to do it.
lol yes
Koichi is human and will eventually die, does that mean Miroku and the kids will be there forever but Koichi will die ??
