Kanon

Age: 16
Birthday: October 6
Blood type: O
Likes: Trimming roses, Lady Jessica
Dislikes: Himself

A young servant of Kinzo's mansion. His real name is Yoshiya (嘉哉?). He is a serious and fervent servant, carrying out his master's orders thoroughly. He is a bit frail and antisocial. He considers Shannon as an older sister and highly disapproves of her feelings for George, as he believes she should not feel love as she is only furniture. He has feelings for Jessica, which he tries to hide from even himself, because he thinks of himself as "furniture", rather than a human being. However, it is shown that he still deeply wishes to become a human being, and hopes to do so when he reaches the Golden Land.

In Dawn Of the Golden Witch, he confesses to Jessica and they become a couple. He is willing to do whatever he can so he can be with Jessica as a human and be worthy of her love. Based on what Beatrice has shown Battler, he is able to use a red blade of light in battle and link with Shannon. Despite seeing himself to be in despair, he actually has surprisingly good relations with others on the island.

Kanon is actually one of the personalities of Sayo Yasuda, who is the child of Kinzo and Beatrice Ushiromiya. "Kanon" is the embodiment of the Yasu's teenage repressed self, as well as her masculine side. Started his existence when Yasu became suspicious of her body condition.
