Рікуґо

Rikugou's primary role is to be the on-call bodyguard to Seimei but he will leave Seimei's side to aide Masahiro should he be ordered to. Rikugou's sense of loyalty is so strong that he was willing to put aside his doubts regarding Masahiro's abilities and accepted him as Seimei's successor on little more than his master's assurances. He differs from the other Sheishou in that he rarely use magical attacks, preferring instead to fight opponents head on with a barbed spear. Rikugou can also use his cape as a shield and create an explosive 360 degree shock wave of air by striking the ground with his weapon. He also has a chain that was used against a 'controlled' Guren but Guren overpowered him.

Rikugou is a man of few words and only speaks when he must. The only way to notice any change in his emotions was through his eyes. This began to change, however, after he met Kazane whom he fell in love with. Rikugou saved Kazane's life two times. One, when she was swallowed by a demon and the other is when they're in the underworld. He began to show worry, frustration and was furious when she was killed. Just before she died, they shared an emotional embrace and he revealed to her that his name is Saiki(彩輝), and that she is the only one he told his name to. He gets along fabulously well with Mokkun.
