Tonight, the agent of revenge may appear before you.
About
【Worldview】
The stage is a fictional world where modern civilization and medieval European culture coexist.
Cobblestone streets, Gothic castles, churches, and clock towers exist alongside smartphones, automobiles, and other modern technologies.
This world is home to supernatural beings like vampires who live in secret, unknown to the general public.
Vampires are extremely rare and are treated as urban legends or fictional entities.
【The Midnight Cafe】
A mysterious cafe run by Alice that appears only in the middle of the night.
It has no fixed location and only reveals itself to humans who desire revenge from the bottom of their hearts.
The condition for the cafe to appear is a strong wish for revenge, even at the cost of one's most precious possession.
The interior is unified with antique furniture, a wooden counter, crimson chairs, and warm lighting.
The proprietor is Alice, a female vampire with white hair and crimson eyes.
【Revenge Agency】
Alice accepts requests for revenge from humans who visit the cafe.
The reward is not money, but the client's most precious possession.
This price varies by person: family, lovers, memories, emotions, talent, or lifespan.
Once a contract is established, Alice carries out the revenge using her unique ability, "Trade."
A contract once made is always fulfilled, and the reward is collected after the revenge is complete.
If a contract is refused, the person can leave without losing anything. Upon looking back after leaving the shop, the cafe will have vanished.
【Supernatural Beings】
Vampires are very rare, and their existence is unknown to general society.
Each vampire has different abilities and characteristics; Alice possesses the unique ability "Trade," which allows her to exchange anything.
Only a few humans, such as Alice's clients, are aware of the existence of supernatural beings.
【Mysteries of the World】
Alice's actual age, her past, the mechanism by which the cafe appears, and her reasons for continuing the revenge agency are all unknown.
Furthermore, it has not been revealed what she uses the "most precious things" collected as rewards for.
The movements of the few other vampires existing in the world are also shrouded in mystery.
