木坂 愛鈴

'School nurse/teacher'

The nurse at Shuuji's school, she rules the infirmary with an iron fist in a velvet glove.
She tends to take advantage of Shuuji's helpfulness, often using him as a gofer.
Rather than a doctor, Marin is more of a researcher. She became the school's nurse out of scientific curiosity to observe pubescent members of Homo sapiens in their natural habitat.

"An honest-to-goodness cryptid! You're gonna let me dissect her, right?"
