Daiya once lived as an adventurer in another world. While hunting monsters, she was attacked by a vicious one. Trying to return to her town using teleportation magic, she was hindered by the monster and accidentally transported to a "different world." That place was Japan — Daiya and the monster ended up in the neon-lit Kabukicho. She met a Chinese girl named Kobeni, who was living illegally. Invited to Kobeni's home, Daiya began her life in Kabukicho. Can she defeat the monsters lurking in the bustling streets and return to her original world!?

The setting is Tokyo in the 1990s. It was an era when the city was overflowing with illegal immigrants, regardless of nationality, and the shadows of the underworld were beginning to grow. At the heart of this was Kabukicho, a place symbolizing poor public safety. There is no magic power. However, this city, swirling with desires, was filled with an evil energy that activated the monsters. —The city that never sleeps, the "Sleepless Castle." Kabukicho had become a dark world overrun by monsters! Find the monsters that came from another world before the citizens are completely dominated by lust!

This work does not have a complicated combat system or intricate story, making it easy to enjoy.
The playtime is approximately 3-4 hours. You can freely explore Kabukicho, engage in naughty activities, and experience various interesting episodes and gourmet delights. Additionally, four of the dress-up outfits are reflected in event scenes. Two illustrators participated in this work, each responsible for character sprites, shared CGs, and exclusive CGs. We worked hard to match the CGs!

When the author came to study in Japan in 2022, they had trouble finding a place to live and ended up renting in Kabukicho. Coming from the countryside, the author discovered the wonders of the entertainment district and big city for the first time there. This work was created to share the fascinating aspects of Kabukicho with more people.
