Tsutomu Kuroki

An overworked but good-natured Japanese office worker that Lily takes a liking to. Due to his mid-level position, he's often forced to relay information from higher-ups to his juniors and aid them in communicating with their seniors, which makes it harder for him to do his own job in time, often forcing him to do unpaid overtime.

Much to Lily's frustration, most of his requests for her are extremely down-to-earth (and often related to his nostalgic memories from early childhood) rather than sexual in nature.
