One clear day with springtime just around the corner, Tenchi happens to hurt Ryo-Ohki's feelings. It was because of some misunderstanding which eventually gets rectified, but Ryo-Ohki cannot quite back to her normal cheerful self. Then, "The Mass"(meaning the element of all things), a strange space creature kept in Washu's lab as a subject of her ever-troublesome experiments, comes into play to make things even worse. Ryo-Ohki's fervent desire to help Tenchi is picked up by The Mass, which causes the situation to head in an unexpected direction...Will Ryo-Ohki's wish come true?
