Koteosa-kei visual rock breaches the membrane between worlds as ALICE NINE. resurrect 「界」 (Kai / “Realm” or “Boundary”) in a new live video. The song operates like an existential particle accelerator: Tora and Saga construct a dense guitar-and-bass gravitational field while Shou sings from the unstable border between memory life death and whatever dimension keeps all the really expensive stage fog.
Originally released as track six on the band’s 2022 album GRACE, 「界」 surrounds its metallic pulse with images of boundaries rebirth and love persisting beyond physical existence—essentially quantum entanglement for visual-kei romantics.
The performance is archival voltage rather than a newly announced single: ALICE NINE. entered an indefinite activity freeze in September 2023.
