Ultimo

Ultimo is the strongest good dôji and the leader of The Good Dôji Club.

Along side Yamato Agari, Ultimo serves as Yamato's dôji. He served along side Yamato's early self, before he was reincarnated, in his early era of creation and had traveled through time just to be with the current reincarnation of Yamato. Ultimo's loyalty to him is undetering, as shown in the manga.

There is some controversy as to what Ultimo's true gender is, but from being shown in the manga, it is depicted that he is male. However, the true gender of Ultimo can only be seen in the eye of the beholder. In that aspect, he is genderless. Also, because he is a dôji, he does not have a true gender, for he is artificially made.
