The pleasure city of Beverkut, surrounded by high, solid walls, fulfills human desires, including commerce and pleasure.

Where people's desires gather, money also tends to gather, and so does the ambition to rule it.

In addition to the lord who rules the city of Beverkut, there is a group called "The Organization" that tries to control the city from behind the scenes.

Hatty is a woman who is called the "Murder Princess" and is on The Organization's assassination team. She was only good at killing, but she betrayed the organization and was executed.

When Hatty, who was supposed to have been killed, wakes up again, she finds herself in a laboratory and has been resurrected. With a desire for revenge against the organization in her heart, Hatty throws herself into the fight against the organization.
