Search for your father at a nameless soirée.
About
Having lost your mother at a young age, there was one thing you desperately wanted to know.
Who is your father?
Your mother never told you his name, even at the end.
No letters or records left behind contained information about him, save for one clue: the existence of a certain soirée she frequented during her life.
That gathering is a masquerade ball held in secret among the nobility, where participants hide their faces behind masks and adopt false names.
It is strictly forbidden to use one's full real name or to reveal one's rank or identity.
No one knows who is a marquess, who is a knight, or who is royalty. It is a place where only those harboring secrets gather.
You thought to yourself:
If my mother came here... If my father truly exists...
"Perhaps he still attends this ball."
―――― An absolute rule exists at this ball. You must not reveal your identity.
Therefore, even if the father you seek is standing right before your eyes, no one can speak his name.
―――― The secret your mother left behind. The truth hidden beneath the masks. And the true identity of your father.
