The middle brother of the Oni trio, Zekki is the most cruel and heartless beings Nube and his allies face. Although he appears like a young teenage male, he is an extremely powerful and dangerous being who takes pleasure in killing anyone who gets in his way: male or female, young or old. His greatest peculiarity is the usage of musical terms (and even a baton) to describe the carnage and destruction he creates. Zekki comes to the human world after three years of climbing in search of the man who now possesses his brother Baki: the exorcist-teacher Nube. After easily thrashing Izuna Hazuki the Itako girl, he makes easy work of Nube, Yukime and Tamamo in order to see the hidden "power" the teacher supposedly used to seal Baki in his hand. Once he realized that Nube did not seal his brother on his own, relying instead on Minako's control from inside the oni, he decides to stay his hand no longer. The battles between the trio and Zekki grew more desperate, with Nube on the losing side despite the help of a true demon-sealing bracelet. After sacrifices made by Nube's students, Yukime and Tamamo, Nube voluntarily unsealed the oni inside his hand and was apparently consumed by Baki. He retained his human heart, however, and after defeating Zekki was revived by the mermaid Hayame. (Source: Wikipedia)

A perverted high school student. He hates his father believing him to be the reason his mother died. He wields a power known as "blood pointer" which allows him to drain "element" from the people around him through his mouth. He has periodically used this ability throughout the series without knowing it. After the battle with the Venus unit he has begun to undergo training to understand this power and use it. He is the childhood friend of Haruko Ayama. His maken is known as "Overblow", which lets him cause his opponent's maken to gain incredible power and overflow with element causing it to go out of control and force the user to not be able to use it. However, when his opponent is able to contain the overflow of element or has perfect control over his maken, it would only provide his opponent greater power or even make the maken evolve into something greater.
