One of Tenchi's cousins, Seina Yamada is undoubtedly the most unlucky person I have ever known. His luck can be so bad, that it can affect people easily around him. However, he is lucky in one department. . . the women! All of them seem to adore him, but sadly, he is oblivious to there feelings. Yamada is an overly cautious person, but never afraid to show his feelings at critical moments.
