Bomberman jetterz was cute and bittersweet, but it has bomberman (the game character) so... maybe not
Wolf children tho! Damn was that movie beautiful but prolly not for 13 yos.
Summer Wars was great tho! and iirc had no nudity/sex mentions.
Princess Tutu, but the problem is ahiru turns naked when she gets hit with water while a duck. It's not sexualized imo, but it happens, moreso for comedy if anything else.
Also!! Letter to Momo!!!!!! It was an amazing movie that I loved to death and is great for kids.
Space patrol luluco, but it's rated pg-14 rip
natsume's book of frăźah, pg-14 again, fuck
