1/2 (Rurouni Kenshin)

1/2 by Makihara Noriyuki is the odd emotional center of the Rurouni Kenshin soundtrack — an acoustic-leaning J-pop ballad built on gentle piano chords and restrained production that feels almost solitary next to its bombastic peers. Makihara sings in a warm, intimate baritone that wraps around every phrase without forcing anything, as if he's confiding rather than performing. The arrangement stays spare for much of the song's duration, letting the piano and soft percussion carry the weight, then expands subtly in the later passages without ever becoming overwhelming. Lyrically, it circles the idea of incompleteness — two people who are each only half of something, belonging together in a way neither can fully articulate. There's a melancholy here that isn't grief exactly, more like the ache of something you understand only in retrospect. In the context of the anime it underscores the quieter, more human moments between characters, the pauses between the sword fights. Makihara was already an established singer-songwriter by this point, and the song carries that maturity — it doesn't reach for spectacle. You'd put this on during the kind of evening where you're not quite sad, just reflective, sitting with a drink and watching the light change outside the window.
