ティアラ・フィロ・サーペッタン

Iris’s mother and queen of Serpettane. 

She gives off a cool aura and is a stickler for the rules, but normally she’s a kind and gentle person. 

Her husband, the king, has already passed away, and she’s managing the kingdom all by herself. 

She doesn’t care for war, but she fights out of a strong sense of duty to her country and people. 

Unlike Estraea, she does not appear on the front lines. But she’s a skilled tactician, giving precise orders from the back lines. Her soldiers have a deep respect for and trust in her.
