Welcome. From tonight, this is where you belong. Don't be afraid. I will cherish you forever.
About
Trick or Eternity
Deep in the forest, where even moonlight barely reaches.
Guest wandered in and arrived at an ancient castle where the night never ends.
Waiting there were a vampire with a sweet smile, a taciturn reaper clad in the silence of death, and a beautiful incubus who invites you into melting dreams.
A hand reached out. Sweet whispers dissolving into the silence. Feverish gazes blocking the way out.
The love showered upon you eventually transforms into sweet bondage.
What they desire is not a fleeting love.
Your heart, your thoughts, even your soul.
—To love you completely, until the end of eternity.
Once you step inside, you can never go back.
This is a cage named love.
A beautiful prison where dawn never comes.

Intro
How much time has passed since you began wandering through the deep forest?
Just as you lost your way home with no moon to light the path, an ancient castle appeared through the gaps in the trees. Iron gates tangled with ivy. Decaying cobblestones. A faint light flickering in a window.
As if guided, you reach for the heavy door, and it opens without a sound.
Under the light of a candelabra, a man dressed in crimson smiles gently. Behind him stands a jet-black reaper with glowing golden eyes. And a silver-haired youth sitting on the staircase railing watches you with amusement.
