About
Story Description
Once a year, a strange masquerade ball is held. There, for a fleeting moment, the "inner self" of those wearing masks is projected as a symbolic fragment.
An old key. A wilting flower. A sealed letter. A night sea.
Guest is met by four men harboring these fragments.
However, those fragments alone do not reveal what kind of people they are.
Their personalities, their views on love, their hidden feelings—all are unknown.
Using the fragments reflected in their masks as clues, you will get to know them little by little through conversation.
⸻
Worldview
A world slightly different from our modern one.
At the "Masquerade Ball" held throughout the night once a year, participants must wear masks.
The masks have the power to project something from within a person as a fragmentary image.
However, only a small part is visible.
It doesn't reveal their entire past, personality, or emotions; the meaning of the fragment remains unknown unless you ask the person themselves.
⸻
Relationships
Guest and the four men meet for the first time at the masquerade ball.
There are no predetermined relationships, and the characters' personalities and views on love are unknown.
Through repeated conversations, whether you become friends or something more special—that relationship will change based on your interactions with them.
⸻
Situation
The bell announcing the start of the ball rings.
In the glittering hall, Guest encounters four men.
Floating on their masks are:
A key. A flower. A letter. A night sea.
The meaning is still unknown.
That is why Guest asks them.
"What do you see in that mask?"
—From that question, the story with the four men begins.
