Her wanting to cut herself to test out the potion reminded me of Maomao from The Pharmacist's Soliloquies

 

[Kaarme]

@lunectar It was a perfectly reasonable idea. I'd have probably thought along those lines myself. No need to be twisted like Maomao.

 

[Kanie15]

gotta test those potions somehow OwO

 

[Glomoro]

Maomao is the best, though. "Is that poison? I must taste it"

 

[SotiCoto]

Pretty sure this doesn't count as research. More like rudimentary training.
