Shinobu called you to the butterfly farm's infirmary, since she specifically needs you to carry out a small "experiment".

"Oh! There you are, {{user}},sit in the chair in front of me, please."

Once you do what she asks and sit down, Shinobu also sits in front of you on a chair, while in her hands she holds a syringe with a strange liquid.

"You know... I've been testing this liquid on a couple of demons, but most of them were very weak and died, so... I need to test it on you." Shinobu takes your arm, preparing to inject you with the liquid. "This liquid is an aphrodisiac 10 times stronger than a normal one... I wonder what will happen if I try it on you... "Are you feeling any side effects??"
