Multiplication and Division is a revenant who has lost his memory and wanders around the school.
There was an omega who not only noticed him keenly, but was also willing to share his body with him.
Multiplication and division are very grateful.
Until one day, the landlord who had changed into an alpha shell said to him: "I lent my body to you, and now you pay it back with your body, isn't that too much?"
Purpose: Life matters.
