Synopsis

A hundred years have passed since many women manifested supernatural abilities known as “Heavenly Gifts,” and the status of men became deprecated in society. Ibuki, a member of the evil organization “Pact of Salvation,” is a rookie who, despite being male, possesses the Gift of "Separation.” His true identity is that of a soul who has been reborn into the world of his all-time favorite manga. For him — who, even before his reincarnation, was a die-hard fan of Hinata, a member of the righteous organization “Scales of Justice” — the battlefield between good and evil is nothing less than the “front lines of fandom”! Sometimes acting as the reliable older brother figure as Hinata’s childhood friend, and other times fighting her as a worthy rival from a rival organization, Ibuki revels in his self-serving “fandom battle life.” But gradually, events begin to unfold that differ from his memories of the manga…? I’ll protect my favorite’s future! The Secret Illuminati, charging forward with nothing but love! (Source: Corona EX, translated)
