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.
Characters
Rei (Protagonist)
"U-Um, can you tell me where I am!?"
A young man who lost his memories. He's deemed by Irene, the city administrator, to be the Messiah.
He has no idea why he was in cryosleep nor why he woke up in this world. Even so, he finds the melody Lisa likes humming quite nostalgic.
Once the secrets of the world come to the forefront, Rei has no choice but to play his fateful role.
"My name's Lisa. Lisa Caster. I'm in charge of... well, chores, I guess..."
One of the main heroines, and a member of the team tasked with helping Rei recover his memories.
She tackles whatever problems she faces head-on rather than wasting time thinking them through. As frank and full of emotion as she is, she's considered a weirdo by other residents of the city.
Always true to her own emotions, her presence tends to drag the cynical Rei into unfamiliar territory.
"I will assist you with anything that could help you recover your memories, Lord Messiah."
The other main heroine, and leader of the team helping Rei recover his memories.
Erika is meticulous, has a strong sense of responsibility, and despises anything she sees as wrong.
Although she knows to treat Rei respectfully as the Messiah, her heart wavers as time passes.
"I'll do my best to help you even more. ♪ I can't wait to see what kind of future you'll bring us!"
A young woman who is adept with technology and processing data but tends to come off as an overly talkative nerd.
As carefree as Iris may seem when together with Rei, she succumbs to anxiety easily and is unusually terrified of death.
Although she likes to tell others how mature she is, she can often be found tripping over her own feet.
"This way please, Lord Messiah."
The supervisor overseeing Rei's protection as he recovers his memories.
Even though she acts like a stickler for rules, she has a kind heart and struggles to stand up for herself when push comes to shove.
She has good posture, more so to hide her lack of confidence than anything else.
"I know that you're supposed to rest your head in my lap at times like these. ♪ I looked it up, y'know? ☆"
An innocent and pure-hearted girl who never fails to brighten the mood of those around her.
Though she can come off as selfish and stubborn, deep down she's just lonely and craves connection.
She tends to invade Rei's personal space, making his heart race every time.
"Lord Messiah woke up. He shouted loudly. His vocal cords appear to be healthy."
An extremely curious spirit whose expressionless face makes her difficult to read.
She excels at rational thinking and only speaks when absolutely necessary. Her observational skills are second to none, and she never takes her eyes off Rei. However, he finds her habit of examining things up close and personal rather unnerving.
"So, until your memories return, we'll have you stay in a special facility."
The administrator of Initium, the Domed City. For reasons unknown, she declared Rei the city's "Messiah."
She is considered the most powerful among the TUNED, commanding their fear and respect.
A certain rule Irene lives by ends up drastically changing Rei's fate.

We've translated it so you can take a look!Shota Horie (Phyz):I was responsible for the main theme songs, insert songs, and putting together the teams who made the music accompanying the game. Since this is a story where both instruments and music have immense symbolic value, I wanted that to be expressed through the sounds we produced. This is a game that lets young musical talents such as Sena Wataru, Akki, Ginnojo Hoshi, and Okamura Daisuke shine in the drama engulfing its world. I hope you'll give it a chance.Read full article on Community Announcements (DariodomsH)AnnouncementsOfficial
