A TV anime tie-in single by ASH DA HERO, their first in two years, centered on "BELIEVERS", the opening theme for the TV anime "Wistoria: Wand and Sword" Season 2. A passionate, straightforward rock number in true ASH DA HERO style, newly written around the theme of "the power to believe". The coupling tracks include "Prologue", a song from the beginning of ASH DA HERO, rebuilt as a 2026 ver. reflecting where they are now, 10 years later, and a self-cover of "MANIFESTO", a GYROAXIA song written and composed by ASH. In addition to the theme song, it also includes an origin track, a track from another IP, and an instrumental, making it a mini-album-level release.
