Kagutsuchi Haruma

Японское имя:

神倶土 春馬

Haruma was previously the fourth member of Aoi, Minami, and Akira's Monster Strike team until he moved out of Kaminohara for reasons they cannot remember. After Ren defeats Doom, it is hinted that Haruma is somehow responsible for his lost memories, as well as the memories of the others. They track Haruma down in Shibuya, only to be easily defeated in Monster Strike, resulting in his demand that they become the top players in Kaminohara before speaking to him, again. After they succeed, he still refuses, and it is revealed that he is being controlled by Memento Mori, the Spirit of War, one of the War Gods posing as his allegedly dead mother, so they seek to free him from her control. His signature monster is Underworld Rebel Lucy.
