妙見 ひな

The homeroom teacher of the class to which the main character moves.
One of the teachers in charge of "supplementary lessons".
She has a light personality with a weak manifestation of intention and not so many words.
She's not bad at communicating, but she has a unique pace and often makes subtle disengagements or misleading statements.
She is still accepted by her students as a sister-like teacher she wants to protect because her words and gestures convey her kindness and honesty. ..

She often sleeps at a private observatory on the roof of the school, and she feels like she's half settled.
