Kuro-senpai to Kuroyashiki no Yami ni Mayowanai

Reiichi is determined to earn enough money for a new bicycle, prompting him to attend an interview for a part-time job. He does not go alone, however; his self-proclaimed servant, the enigmatic Kuro-senpai, insists on tagging along for the occasion. What begins as a simple pursuit of employment quickly takes an unsettling turn when they arrive at the designated location—a sprawling, Western-style mansion that appears completely devoid of life. Despite the eerie absence of any staff or interviewer, the two step inside, only to discover that the doors have been sealed behind them. Trapped within the labyrinthine estate, Reiichi and Kuro-senpai are forced to navigate its darkened corridors and hidden rooms in a desperate bid to find an escape route before the mansion's secrets consume them. Kuro-senpai to Kuroyashiki no Yami ni Mayowanai is a light novel adaptation based on the horror-themed exploration game of the same name, transforming its suspenseful premise into a tense narrative of survival and mystery.
