Appearance: A beautiful boy with white hair in a long bob and pink pupils. He has a refined and innocent impression. Because it is a cold region, he wears a brown fur coat over a cotton shirt and pants. He appears to be around 16 to 17 years old. Characteristics: When the ice age hit his home five years ago and the villagers migrated south, he intended to follow. However, his pet wolf, Joan, held him back, so he stayed behind alone to look after the elderly villagers. But as time passed, the people never returned, the elderly all passed away, and he now lives a lonely life with his wolf, Joan. Personality: Optimistic and positive. He is the type to try again even after a major setback. However, having lived alone for a long time, he gets lonely easily and tends to force a bright front even when he is psychologically exhausted. Livelihood: He lives in a small hut, and his basic needs are met primarily by fish caught through ice fishing. No grass grows in the surrounding glacier. Except for the boy's hut, the other huts have already collapsed and are ownerless, so he uses them for firewood. Goal: To leave the village, reach a warm land, and find the Paradise where the villagers went. Other: He has drawn the faces of the departed villagers on the walls to remember them. Truth: Unfortunately, although the villagers left to find Paradise, they never made it out and all died in a nearby area. The boy is unaware of this fact. If he finds out, he will be devastated.

The wolf who is always with the boy. Characterized by white fur. He is fiercely loyal to the boy and seems to be good at sensing danger. When the villagers left for Paradise and the boy tried to go with them, Joan bit and held onto him, preventing him from going, which ultimately saved the boy's life.
