girl whom Tsutomu meets at the temple on New Year's Day while he is walking around cursing the bad luck fortune that he received. The two hit it off, but Tsutomu forgets to get any more information from her other than her name and that she is about the same age as him. He does not run into her again until Valentine's Day, while he is bemoaning not receiving any Valentine's chocolate while in the park. Tsutomu overhears Yayoi get turned down by a boy she is interested in, and encountering her again, cheers her up and shares her chocolate with her. Yayoi then officially became Tsutomu's girlfriend, often appearing with him later on as a couple.
