Hoshino Riho Is Being Experimented

When talking about experimenting, the things that came into Hoshino Riho's mind were blood drawing, and hair, skin, and body tissue sampling. 

Whether there had been a change in body and bone structure when a human was transformed into a yokai, it could be easily detected by doing some scans with a machine, just like a medical check-up. 

However, things would be a little different if it was organ sampling. To get a sample from an inner organ, one's body had to be cut open. Generally, a procedure like this required anesthesia, but Hoshino Riho could not be sure if anesthesia would have any effect on her yokai body. If it did not have any effect, then she had no choice but to bear through the entire operation while gritting her teeth. 

It would be very painful, right? 

Hoshino Riho was afraid of pain.
