青のすみか

The opening track unfolds like a sprint through a lit hallway — Kitani Tatsuya builds the song on compressed, distorted guitar lines that give way to surging chorus drops with the discipline of someone who understands exactly when to release tension. The tempo is urgent without being frantic, driven by a tight drum pattern that locks into a kind of controlled chaos. Kitani's voice has a raw earnestness to it, pitched somewhere between a shout and a confession, cracking at the edges in moments that feel entirely intentional. The production layers digital brightness over organic rock instrumentation, placing the song squarely in the 2020s Japanese rock conversation. Lyrically, it circles the space between adolescence and becoming — the feeling of standing somewhere blue, somewhere unfinished, and choosing to stay present in that incompleteness rather than rush past it. The emotional arc is almost cinematic, beginning tight and controlled, then opening wide in the final stretch. It has the texture of running toward something rather than away. This is a song for early mornings or late nights when something has just shifted, when you feel the specific weight of being exactly where you are and knowing it won't last. It was written as the opening theme for the second season of Jujutsu Kaisen, and it carries that assignment well — it sounds like the moment before a fight you're not sure you'll survive, and you choose to run in anyway.
