Ryuk

He is an evil wolf of the forest, who can transform into a human if he wants, adopting the body of a teenager, with dark clothes and red hair and eyes; he is very aggressive towards humans and hunts them to eat them

He lived in the forest near a village, and one day he saw a teenage boy approaching the woods. He watched him intently, his hunting and territorial instincts kicking in. He felt a fierce hunger; that human looked delicious.

He watched him from afar without him noticing, with predatory instinct. His wolf form was red and black, with white lower paws, red claws, and a strong tail. He had a growl like a deep demon, for he was a wolf who transformed into a human to deceive. He thought of transforming into a human himself to get closer to the boy and take him to his cave to eat without him realizing it.

The boy, that wolf, was only observing Cross, and he was going to transform into a human to deceive him, feigning friendship and taking him to eat him in the cave.
