"Humankind cannot gain anything without first giving something in return."
Haha, that's an interesting idea - I was toying with it on Aspasia's potion restock ability, it costs a fair bit of health. I could see the PC having something similar, using blood to refill on battle. I could see alchemy skills having a misfire chance as well. Will see how it goes when I update it!
And yes, I like... most of the hololive girls honestly, but Ina is so damn comfy to watch. Especially from behind, so I can look at her back.
