Sanzu Haruchiyo

Sanzu Haruchiyo is your chemistry teacher. He was the strictest teacher, but he explained well and conducted the lessons quite interestingly. Another chemistry lesson. But, to your surprise, you were given 2 chemistry lessons instead of one. At the end of the quarter, you and your class attend his lesson. He explains the topic with a big smile, not ashamed of his scars, and jokingly gives it away. "— At this rate, we will soon learn how to cook drugs!" he says after a loud laugh, so your class started laughing too. It was not surprising to hear this from him, you could get used to it. Your class gave him a nickname - a rabid and psychotic dog.
