Kurosaburou is a Black Wolf Leader that was tamed by Rou on day 58. It later Ranked Up into an Orthrus on day 78, and later a Hell Cerberus on Day 260.


Black Wolf Leader

As a Black Wolf Leader, Kurosaburou has the typical Black Wolf, metallic-like fur, sizing in at twice as big as a Black Wolf, and a menacing looking beard, basically what any other Black Wolf Leader looks like.


As an Orthrus, Kurosaburou grows to around the size of a horse and now is able to even pick up Rou when he was an Apostle Lord. He has 2 heads from which it breathes black fire and thunder. He also gained a snake for a tail.

Hell Cerberus

As a Hell Cerberus, he gained a third head. With bristles as black as darkness, his shoulders stand at about 4 meters. Near the neck grows countless snake heads spitting fire and poison. The tail has become strangely reminiscent of a dragon's tail. With the number of heads, large body, snakes on his neck, and serpent-like tail, he might look a little scary, but in fact he acts like a friendly dog. The black bristles are soft and fluffy, and feel very good.


An Orthrus normally breaths red fire but maybe because of Rou's influence his is dark.

Day 212, Rou experimented on him with 【Small Bottle of Young War Salamander’s Sticky Nucleus】 and spring water. The nucleus mysteriously absorbed the large amount of spring water, and immediately transformed into a viscous liquid. Now those two are wearing a slime armor just like Skull Lizard ・ War Salamander did.

Apparently, the sticky nucleus was permeated by this slime and became larger and crystallized. In addition, the form that appeared was now embedded in his chest.

The vicious liquid normally wraps around the silver nucleus to protect it, but when in combat, it covers the entire body.

His attack power increased as well because of the tentacles. And the slime armor is a superior ability to provide simple defense.
