>>93334691yeah IIRC in the context of the movie the world is a big depressing dystopia and their family runs a shop that sells suicide kits or something, the son is the oddball of the family and is super upbeat and shit, so when he finds out his sister does something that makes her happy it's kind of a win for him
and yeah, French cartoons and comics are weird as fuck - the French have a very nonchalant attitude about sex and nudity and so you'll often find /co/ material meant for kids that comes across as pervy and NSFW
