As Tenma's younger sister, Yakumo has built up a high tolerance. She maintains the house, prepares all the bento boxes, cooks dinner, and generally sacrifies much of her time and energy into helping her older sibling. Despite the work, Yakumo remains unfazed and placid, taking life at a slow, reflective pace. She may be shy, but underneath her mild mannerisms she has a big heart.
