Moose Fangire

Moose Fangire (ムースファンガイア): One of the Checkmate Four's most loyal servants, Kurosawa promised Maya that on his life that he would guard Taiga Nobori. However, he worries for Maya getting too close to humans.

In 2008, Kurosawa continues that vow as Taiga's aid in the D&P Company, serving as an assassin to take out humans who may revolutionize the world. However, when he attempts to kill Mio Suzuki for following the same path as Maya, Taiga disowns Kurosawa and drives him off on the vow to kill him if he ever pulls a stunt like that again. But when Kurosawa attempts to kill Numakawa, he is found by Kiva and destroyed when Kiva uses the Dogga Hammer in Emperor Form.
