Why am I not seeing One Piece in here? It sexualizes nami and Robin but they are both over 18. There aren't really relationships at all in the show unless you count boa hancock but that's pretty tame and not a relationship
Animemes
Does ReLIFE fit the bill?
Steins;Gate (correction: episode 8 unfortunately has >!Okarin!< grope >!Luka!< because he doesn't believe that they're actually >!a girl in this worldline!<. Everyone rightfully calls him out for being a creepass)
Castlevania (shut up yes it is)
Vivy: Fluorite Eyes Song
Violet Evergarden (edit: NOT THE MOVIE)
Hyouka (skip the ova)
Belle
[Redacted]
Baccano
Deca-dence (I think)
Trigun
Akudama Drive
ACCA: 13 Territory Inspection Dept.
Fullmetal Alchemist
Spy Family
#Mushishi
5 Centimeters Per Second
Afro Samurai
Your Lie In April
Nichijou
Odd Taxi
Cowboy Bebop
Canaan
Sk8 the Infinity (arguably I guess because Adam is a creepass)
A Place Further Than The Universe
Supercrooks
Bocchi the Rock
House of Five Leaves
Weathering With You
#Haibane Renmei
Thus concludes the exhaustive list of animes I watched where I didn't have to put up with any sexualization of minors
If you only take one anime from this list, let it be Mushishi
I wish I'd seen Haibane Renmei by the time I initially made this list. Watch that too!
