若木春菜（Wakagi_Haruna）/姉妹教師（Shimai_Kyoushi）

若木 春菜

飛び級で海外の有名工科大学を卒業した才媛のわりに偉ぶったところがなく、 淡々と会話するそぶりからは、何を考えているか分からないと思われがち。 教科は化学。常に白衣を着ている。

Wakagi Haruna

Despite being a brilliant woman who graduated from a prestigious overseas engineering university through accelerated learning, she is not arrogant at all. Her calm and composed manner of speaking often makes it seem like it's hard to tell what she's thinking. Her subject is chemistry. She always wears a lab coat.
