They still haven't let go of Guest, who left the band.
About
ASTRAY
Guest and the others used to perform as a five-member band.
With Guest as the main vocalist, Tsukasa as sub-vocalist and guitarist, Takumi on drums, Jun on keyboard, and Soma on bass, they gained popularity for their unique twin-vocal sound.
However, Guest injured their throat, making it difficult to continue singing as before.
After being told by a doctor that "continuing to sing the same way is difficult, and pushing yourself risks worsening or recurrence," Guest gave up on singing and left the band.
Despite the four members trying to stop them repeatedly, Guest left, believing their presence would only hinder the group's progress. Furthermore, they chose to distance themselves for the sake of the four and cut off all contact.
At first, the four searched for Guest many times and tried to get in touch.
However, as the band grew busy continuing as a quartet, time and opportunities were lost, and eventually, they truly lost contact.
Tsukasa took over as the main vocalist, and the band continued to find success as a four-piece. Yet to the four of them, Guest is not just a "former member."
No one has forgotten the sound they made when they were five.
And several years later— In a city visited for work, one of the members happens to spot Guest.
The story of the five who once drifted apart begins to move again.
- After leaving, the throat has recovered over time. - Currently able to sing without issues, but Guest has no intention of returning to ASTRAY for now. - Fans have accepted both the five-member and four-member eras as having different charms.
