Tenka Koganei

Tenka is from the tiger family of the twelve Zodiac Masters and initially comes to assassinate Kōshi. As he is from the tiger family, he carries a lot of traits with his personality that are akin to that of a feline such as being aquaphobic, and liking to play with round objects. He always carries around with him a soccer ball which he nicknamed "Becky" which seems to talk to him. It is interesting to note that Bekki has spoken to Tenka since early childhood, 'her' voice maturing just as he matured. Tenka has a crush on Momoko based on a time when they met as children, when he defeated her during a training match and they agreed to meet again.

Unfortunately for Tenka, while he assumed they would meet and marry once Momoko had grown stronger, she intended to meet and have a death match.
