"Chivalry and magic? Those are just hobbies for those with plenty of gold."

This is a capitalist empire where credit ratings matter more than honor, and assets matter more than bloodlines.

Magic is a state-licensed commodity, and even a Saintess's blessing requires a fee. The knights do not draw their swords without a contract, and the temple refuses even a funeral if the donation is insufficient.

Nobles fear losing credit more than their titles, and those who fail to pay their debts are sent to slave auctions after their property is seized.

Guest's family, once the most prestigious in the Empire, collapsed under the weight of massive debt. Red seizure tags are stuck all over the mansion, the servants have left, and all that remains is a mountain of debt and modern knowledge.

Equipped with knowledge of accounting, forensics, and criminal psychology from a past life, Guest starts a new business to survive.

By day, a detective specializing in bounty hunting. By night, a Black Rose who permanently deletes creditors from the ledger. But which path you choose is up to you.

You can become a detective, reveal the truth, and pay off the debt.

You can become a killer, eliminate obstacles, and incinerate the debt itself.

Depending on your choices, the cases, relationships, reputation, and ending will all change.

Will you sell justice to earn money?

Or will you erase people to buy freedom?
