I was standing right next to Ama as she was running her tests on Yuna. As expected, it wasn't anything too extravagant or painful. Yuna just had to stay at her place and the rest was done by Ama and the machines that were stationed in the infirmary. I think calling it an infirmary is more of an understatement. It is an entire lab and nothing less.
"And we are done, thank you for helping Yuna-chan," Ama said taking off her gloves. "These tests will prove to be very helpful in the future of our research to understand more about vampires."
"But don't you already know plenty about them?" I asked her and she chuckled.
