Passion at 25 O’Clock25-ji, Naitokōdo de. × KAITO
“Passion at 25 O’Clock” moves the heart with its beautiful vocals and stirring melody.
Crafted by Kanzaki Iori, whose music is celebrated for its nuanced emotional expression, the song delicately portrays the wavering feelings of youth and the journey of personal growth.
In particular, its message—focusing on unforgettable memories, the weight of passing time, and evolving relationships—resonates deeply with listeners.
Since the melody is on the slower side, try to articulate each word with care.

This mega-hit number, written and composed by the hugely popular Vocaloid producer Kanaria, is covered by Tsukasa Tenma and Rui Kamishiro.
It delivers a somewhat defiant, theatrical, and thrilling worldview.
Added to the game in May 2021, it also featured in a collaboration with Ensemble Stars!! in February 2025, drawing major attention.
We recommend singing it as if you’re the song’s protagonist.
