Tamaki Roy – How It Came About

A track included on the fifth album, Nagi, released in 2017.

The music video—where words surface and disappear one after another like cell division—was created by animation artist Ryo Orikasa.

It beautifully captures a world that is mechanical, logical, and melancholic.
