Gleipnir
AOT Season 4 part 1
Also i'm gonna put Mob Psycho 100 and Jujutsu Kaisen, all their OPs and EDs are fire like actual FIRE but I listen to the EDs just the teeny tiniest bit more-
Honestly aside from Gleipnir and that one PART of aot I don't think there's many animes
if any where I like the ED more than the OP, most of the time both OP and ED are forgettable but even then the OPs are often slightly better than the EDs, and if a show has a great ED it usually has a great OP too. I mean there's probs more than i'm giving credit for that I just can't remember in the grand scheme of things that someone else will eventually mention and I might be like 'omg yes that one!!'
