Complexity? What's that?
Anime
Anime that you can watch without having to worry about paying too much attention. Mostly slice of life/episodic anime.
I obviously haven't watched every single 'non-complex' anime, and some entries are from what I've heard of from the anime, so if you think there's something that should be added here or something should be removed, message me.
