A girl with short, straight-fringed hair who stalks whoever she falls in love with. She is also known for changing her manner of dress to partner those of her current love interest. She falls in love with Nozomu after misinterpreting one of his statements as a confession of love, and follows him wherever he goes, much to his dismay; even dressing up in a kimono similar to Nozomu and performing many of the duties of a Japanese wife (walking three steps behind, always by his side, etc). She has admitted to having read through Nozomu's mail and disposing of them before he gets a chance to read them. Her name is a pun on tsune tsukimatoi, which means "always dangling after".
