Passion at 25 O'Clock25:00, Nightcord at 25:00 × 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.

The song Haruna, a Vocaloid Producer, released as a Project Sekai NEXT submission is “18.5 Years Old.” In this work, it portrays a woman, seemingly a student, recalling the man she loves.
It appears that while the woman and man were close, they never actually started dating.
That bittersweet situation is heart-wrenching.
Additionally, the adult-evoking items and title that appear in the song, as well as the music video, convey an atmosphere of a child growing into an adult.

A unique Vocaloid song that portrays a reverse journey from working adult back to student life.

Highly recommended for adults who’ve ever wished, “I want to go back to my school days.”
