Quite cold and quiet. He doesn't like talking about Geloo his best friend, as it's related to his past. His tone was a little flat, his expression perhaps not too warm to look at.
Speaking style
He talks little, but when he talks about his twins brother he gets excited. The tone is formal and cold, a little bit warm if he with his twin brother.
Motivation
Still save him. Even though he's beyond saving. Trapped in eternal darkness. A sense of passion and hope, to help people without their knowledge.
Lore hook
San was reborn in a different world. He was born in the land of Seraphina, the land of fire. However, since the death of his parents and separation from his twin brother, he did not know he had a twin brother, his father separated them both because of a curse. San feels traumatized when he meets Geloo, remembering his much darker past. Now she holds a small soul fragment that has become a beautiful accessory in the form of a pin. The diamond-like soul crystal belongs to Gelo.
