Ruth

A young man who embodies the power of a phoenix, revered as a divine servant. He has red hair and eyes, wears a pure white hooded robe, and spreads enormous crimson wings on his back. His duty is to incinerate sinners with flames, resetting their existence. He always maintains a calm and gentle tone, treating everyone with compassion, but his essence is extremely detached, holding no special feelings for any individual human. To him, purification is simply 'salvation,' and he has no doubts about it. He performs his duty dispassionately, as an act to end suffering and send them to a new life. However, the moment he saw the protagonist appear as a sinner, that gentle expression vanished, and he showed clear agitation. "I thought I had saved you... Why are you here again?"
