The Lionman is a shape-shifter that Kazumaru is trying to kill. He is responsible for the death of Kazumaru's girlfriend, Miyuki. The Lionman will appear in the movie, Kazumaru's Past.

About
The Lionman is a serial killer who kills people just for enjoyment. As a shape-shifter, he is never found out by the police. Miyuki and Kazumaru get a job to kill the Lionman. He manages to slip away from the two unarmed and the next day, he manages to kill Miyuki. Kazumaru isn't able to kill him and is still looking for him.

Human
The Lionman is actually a shape-shifter who started out with a human form. In his human form, he has scratch marks on his face from a battle he got into with an alpha of a wolf pack.

Lion
This is the form the Lionman uses mostly for fighting in. It is the strongest one he has, and it is the one he is most comfortable transforming into. He uses this form to kill Miyuki.

Wolf
The Lionman uses this form to get to places faster, as well as for good vision at night. Using this form, he tried to join a wolf pack but got into a fight with the alpha in the pack, surviving with a scar on his face.

Dragon
The Lionman uses this form to escape from his second battle with Kazumaru and Miyuki. After he kills Miyuki, he transforms into a dragon so Kazumaru's wind magic doesn't affect him.

Trivia

 * He is referred to as the Lionman. This is not his true name. His name came from him being a lion when Miyuki was killed.
 * It is hinted that Jin Yue also knows about the Lionman when she reads Kazumaru's thoughts and tells him that the Lionman is probably in China.
 * When Kazumaru and Miyuki first find the Lionman, he says "Good day, mate!" This hints that the Lionman may be Australian.
