Kurohara Ryou

She belongs to the same organization as the main character and comes to the mansion as a support person. She acts as a maid for the owner of the mansion, but this is just a role she imposes on herself in order to enjoy her work, and is not her main occupation. She is not skilled in housekeeping, but she has a special skill: she can hear a handbell and instantly appear out of nowhere.

She is bright, expressive, vivacious, and unafraid to speak her mind, and has a friendly attitude toward everyone she meets. On the other hand, she is aloof, fearless, and elusive at all times. She is honest with herself, likes to have fun and feel good, and begs the protagonist to reward her with sex whenever she helps him with his work.
