Like a baku that devours dreams, the city swallows you whole…

This Vocaloid track captures that suffocating feeling in sound.

Composed by Tsubaki and released in December 2025, it portrays the nightmare-like sensations that recur in urban life through razor-sharp word choices and richly shadowed sonics.

Created by Afu Otonashi, it debuted in December 2025 and appears as Episode 8 on Yuka Satoishi’s official compilation album Re: Magical Girl.

Beneath its poppy, magical-girl-inspired phrasing lies a weave of overadaptation to righteousness and the runaway urge for approval—sending chills the more you listen.

This is a Vocaloid track with a unique concept that likens oneself to a company.

Known for the smash hit “Goodbye Declaration,” Chinozo features Hatsune Miku NT on vocals and released the song in December 2025.

The central keyword is the stark term “dismissal,” but by setting it to a catchy melody, the piece achieves a curious mix of chilliness and addictiveness.

If you’re grappling with murky feelings about social evaluation or your self-image, this will likely hit home.
