Kalen

Kalen, Kaguro and Naraku (Formerly known as Angustus Arbor) is leader of Demon Hunter, and the first character introduced in Reach BV. Kalen's original art was said to be Denki Denki Arts but that was a lie. His real art has not been revealed by him and has been dubbed "Secret". His real name is also a secret and he has three alternate egos. Kaguro is currently unborn, Kalen is missing and Naraku is wounded due to the mathematics explosion.

He first appeared in Chapter 1 working under Grusso's Hub and entering the January Fight Club.

Battle Shout
Kalen can scream in a high pitch that induces fear, generates vibrations, crumble objects, and can cause temporary paralysis or deafness.

Salire
Kalen activates this ability by putting his right foot in front of his left and starts to hop on that right foot alone. This creates the energy Kalen uses during the technique.

Kalen
Kalen is one of Kalen's alternate egos. In this ego, Kalen's personality shifts frequently. One moment he is serious and mature. He's calm and rarely changes his blank expression. He becomes highly observant and intelligent. Next moment, he becomes optimistic, careless, stubborn and a bit arrogant.

Kaguro
Kaguro is one of Kalen's alternate egos. In this ego, he is destructive and blood-thirsty. Kaguro is also sadistic and barely uses this ego due to his lack of control over it. This is so far his most powerful ego.

Naraku
Naraku is one of Kalen's alternate egos. In this ego, on the outside he is calm, emotionless and introverted. However his true personality shifts during battle as he turns into a foul-mouthed and violent person. He occasionally swears and insults enemies and people that make him mad.
