Story
An intertwining, resonant serenade of love, sorrow, and fateful encounters calls forth a reboot for the future.
Step into the shoes of Rei, who wakes up in the Domed City of Initium surrounded by women calling him the Messiah. Determined to regain the memories he lost during years of cryosleep, he begins living with the six beautiful members of the TUNED (Tactical Unit for Neutralization and Enhanced Defense)-young women who wield so-called harmonic weapons.
Though lonely and confused in a world governed by enigmatic rules, Rei gradually finds comfort in his new companions.
Even so, he knows that something is amiss...
And it will only be a matter of time before the secrets of the world come to light.
