I’m half joking that Jujutsu Kaisen should be called Sorcery Fight
And Kimetsu no Yaiba is Demon Slayer. It literally is translated to something like “Blade of Demonic Destruction”, though using that would make it sound like a donghua title (Mo Sha Zhi Ren, MSZR).
Yeah “Delicious in Dungeon” makes no sense in the same way “Attack on Titan” makes little sense. HOWEVER.
That narrator going “Mmmmh, Delicious in Dungeon! Ooooohh, delicious in dungeon!” at least once per episode is just absolute perfection and I wouldn’t have it any other way.
