Bokurai

Bokurai (Full name: Bokurai Demonis, sometimes called Boku by Shade and Salahar) is a Demonian Spirit and one of the Reapers. Bokurai may be young, but her sheer speed is enough to blind opponents and summon tornadoes at will. Her power is devastating, and she is learning how to control and manipulate it at will from Pandora, whom she easily surpassed.

Personality
The second youngest of the Demonis Siblings, Bokurai is always hyper. She has a positive outlook on pretty much everything, and loves to laugh. Her favorite thing in the world to do is play outside with her little brother, Allagar.

Death
Her death by Nike's hands is not seen, but when Aqua arrives at Stalaria, she accidentally jumps onto Bokurai. When Aqua turns around, she sees Bokurai's corpse on the ground.

Bokurai's blade is used in tandem with Allagar's lance during Aqua's battle with Nike, creating a tornado that allowed the lance to cut Nike everywhere.
