垂氷

Taruhi has an outward appearance of a young boy, but he's actually some kind of non-human creature. Sometimes, he's called "hamushi (small winged insect; louse)" by the mansion's residents. A resident of the mansion as well, Taruhi functions as a caretaker to the others. He usually can complete his chores and tasks (such as the housekeeping and laundry) flawlessly. However, he's not good at cooking.

Though polite with a gentle smile, sometimes what he says is fairly venomous. Ever since Saki and Makoto arrived in Hanari, he begins to undergo a certain "change".
