"Tsukasa's eighteenth birthday party doesn't go smoothly at all! Tsukushi is introduced to Kaede, Tsukasa's mother, by way of falling over a table and causing a scene. Kaede tells her to get out, but Tsukasa defends her by declaring that she is precious to him. Thus begins a three-sided war between the three most headstrong people you've ever seen! Tsukushi and Tsukasa get away for a while and spend some time on Tsukasa's boat, but they can't hide from Kaede forever."--VIZ.
