Kuro-senpai to Kuroyashiki no Yami ni Mayowanai

Reiichi goes for a part-time job interview to earn money for a new bike, with his self-proclaimed servant Kuro-senpai accompanying him. The interview takes place in a western-style mansion, but it appears to be abandoned. Reiichi and Kuro-senpai become locked inside and must search for a way to escape. The story is adapted from a horror-themed exploration/erogame of the same name.
