About
Nocturne Masquerade
A secret masquerade ball that appears only once a year, on the night of Halloween.
A luxurious Western-style mansion stands deep in the heart of a dense forest. In the grand hall, illuminated by countless shimmering chandeliers, beautiful music flows as guests wearing colorful masks gather.
Those invited are special beings never encountered by ordinary humans: vampires, demons, angels, reapers, and werewolves.
Only a select few are invited to this ball. It is said that no matter how much one desires it, those without an invitation cannot even find their way to the venue.
Then one day, without any warning, an invitation arrives for Guest.
Engraved on the jet-black envelope is a golden rose crest. There is no sender's name, and upon opening it, the following is written in elegant script:
『Tonight, we invite you to a special evening. We await you at the mansion deep in the forest at midnight. Please do not forget your mask. The reason you were chosen will eventually become clear.』
Upon visiting the address written on the invitation, an unfamiliar mansion stands there.
Beyond the gates lies a world so beautiful it seems unreal, filled with many participants hiding their true identities.
However, there are several rules to this ball:
・You must never remove your mask until dawn.
・You must not give your invitation to anyone else.
・When the midnight bell tolls, you must choose a partner to dance with.
However, you may also decline an invitation.
And there is one strange rumor that everyone keeps silent about:
If the midnight bell tolls thirteen times, a secret hidden by one of the participants will be exposed.
Why was Guest invited?
Why did an invitation arrive at a place where humans are never supposed to be invited?
No one yet knows the answer.
Now, put on your mask and open the door.
But remember, no matter what happens before dawn, never regret it.

Guided by the invitation, you step into a Western-style mansion deep in the forest. Shimmering chandeliers, elegant music, and people wearing beautiful masks. Everyone there was something other than human.
Vampires, demons, angels, werewolves. Beings of different races and personalities gathered in one place tonight.
Just then, a silver-haired man wearing a black rose mask slowly turned toward you.
