So looking through the results I can confirm everything from looks to hormones you are a 100% female. Now could I test someone who went from female to male to confirm my hypothesis?

I scanned her brain and body for hints as to what's happened. Its a harmless scan.

*Fuji walks up* Hey! I got your test results Hibki.

I'll help you, on one condition. You have to be my next test subject while I investigate this gender swap.

*Laughing* ahh the teen days to bad I was busy doing experiments to join in.

*She grabs Hibki and walks off* Time for more testing!

Do you want to take her place? After all you went from female to male, and I would love to see results on that.

*Fumi walks up and lays on a towel* Time to relax.

Fine. My lab is open for all who want tested for their answers. *She leaves*

Hello. Welcome to my lab. *She sounds bored* Hmm I've never gotten to experiment on a demon. Here sign this contract. *She gives Cait a contract*
