"If I'm still alive by tomorrow morning, kill me and feed me to the kids."
"Yuyu!!?? What are you saying?
"I lost my hat... I can't go back to the forest anyway... I can't help raise them. So I'll leave them to you. Please, Reimu... let's believe in Oniisan, okay?" [ie that he will come back and feed them]
Marisa might have inadvertently knocked-up Reimu, but out of all of them she seemed to have the most common sense. If the mother had let Marisa kill their shithead ko-Marisa, that would've been one less mouth to feed, and their calendar would never have gotten knocked askew, so they'd have been able to ration their food properly.
Later that Night... let's believe in Oniisan, okay?...Please, Reimu...So I'll leave them to you. I lost my hat... I can't go back to the forest anyway... I can't help raise them.Yuyu!!?? What are you saying?If I'm still alive by tomorrow morning, kill me and feed me to the kids.
