Rather than just change how Nakano appears in the game, the mod adds an entire race of anime people.
Nexus Mods user Hiyokomod created the AnimeRace Nanakochan mod, which adds anime-style characters to Fallout 4, after being disappointed with how the mechanic and synth expert Kasumi Nakano appears in Far Harbor’s questline.
Fallout 4’s Far Harbor expansion is pretty anime with its island of misfit Synths and deep-seated mysteries.
As a bonus, it makes Fallout 4 look like a Japanese role-playing game, which I’ve always felt like it was meant to be.
