Asterius

Race: Xenos

Affiliation: Xenos • Ouranos Level: 7 (estimate)

Asterius is a Black Rhinos Xenos. As a Xenos, Asterius is far more intelligent and powerful than a normal monster. He is mentioned by Lyd to be the strongest Xenos and is strong enough to easily defeat high level opponents like Shakti. It was also able to hold its own against Tione, Tiona and Bete. Finn noted that Asterius was relying more on its ability rather than technique, but added that it would be as strong as Ottar if it properly trained its technique. Asterius is a large Xenos, described to be more than two meters tall, with jet black hide, red horns, boulder like muscles, and wears full plate armor that's somewhat small for his size, making it seem like light armor.

Asterius was originally the Minotaur that Ottar trained for Bell to fight. It was unintentionally released and ultimately defeated by the boy.

Asterius has a love for battle, often grinning when fighting multiple opponents, especially if they are strong. Ryuu noticed that he had a desire to fight rather than to kill like normal monsters. Besides this, he is also shown to be very protective of his fellow Xenos, going so far as to fight off the Loki Familia in order to protect them from further harm. He has a deep interest in Bell, due to their battle on the 9th Floor during his previous life, and considers each other to be rivals. Despite his lust for battle, he himself knows he is no match for Ottar.
