一途 (Ichizu) [Jujutsu Kaisen S2 OP]

一途 arrives like a fist. Where King Gnu often lets tension accumulate slowly, this Jujutsu Kaisen season two opener makes its intentions clear within the first few seconds — guitars locked into a grinding, almost mechanical riff, drums hitting with industrial precision, the whole track bearing down with single-minded intensity. The title translates roughly to "wholehearted" or "devoted to one thing only," and the music embodies that singular focus completely. Tsuneta's vocal here abandons the falsetto vulnerability of earlier work in favor of something guttural and declarative, a voice that has made peace with whatever cost is coming. Production-wise it sits in a compressed, maximalist space — everything loud, everything present, no room for doubt or hesitation. The song captures the specific emotional register of anime's most dramatically loaded moments: a character who has accepted a terrible fate and chosen it anyway, without flinching. Outside its anime context it's a song for moments requiring absolute commitment — before something difficult, during something that demands everything you have.
