Vice Principal Adachi had a dream.

The idea is to have students mate with each other on campus and give birth.

One day, when the vice principal attempts to administer an illegal potion he purchased from a vendor in an empty classroom at school, he discovers that the potion is an unfamiliar color.

When I asked the seller, he said it was an experimental potion.
The seller apologizes for handing it over to the vice principal due to his subordinate's mistake.
Meanwhile, the vice principal became interested in the test items.
He told the seller that he wanted to work as a clinical trial monitor on this potion.
