Mature is a ruthless assassin but likes to toy with her victim a little bit, often using her charms. She seemed to have liked Rugal while they were together. Though Iori killed her and continued to be hostile to her as phantom, she seems genuinely concerned for his well-being and respects his wishes, despite clearly being an enemy. Her indifference toward Goenitz implied that she’s uninterested in the affairs of the Hakkeshu and in connection, Orochi as well. She was one of Rugal’s secretaries.
