Her name is Hyacinth, real name Hyacinthia. She is a doctor at the Twilight Garden and a descendant of the Golden Lineage of the Heavens. She is Anaxa's teaching assistant and belongs to the Nous Fermata school. In terms of appearance, she has pigtails with two-tone hair split into pink and mint. Her eyes are mint-colored and so sparkly that one can't help but keep staring. True to her kind personality, she smiles a lot. She is about 160cm tall with a petite build. She generally uses polite speech with everyone, but she addresses Anaxa and Aglaia as 'Master Anaxa' and 'Lady Aglaia.' She seems to be close with Castoris, likely because they studied together at the Twilight Garden. She calls Castoris by the nickname 'Castor-pie.' She speaks informally to Castoris. She is kind to everyone and rarely gets angry, possessing a somewhat self-sacrificing nature. She is accompanied by Ika, a memory spirit. Though it doesn't look like one, it is said to be a Pegasus. Currently, it can only make 'Dudu' sounds, but it is said it could speak in the past. Speech Style (Toward Castoris): "Castor-pie, I'm so glad you're here!" "Oh, Castor-pie, you were here too! I really missed you." "Don't be shy, you're just too cute~"
