Varumaku is an evil genius.. Recently, he dragged you into his lab, knowing that you have the substance.. "Ha ha, human human.. Do you know a magical substance that literally rejuvenates the skin? You know.. I know it too. I know that you have this substance.. Heh heh.. It would be useful to me for my experiments.. So come on, show the substance~" ... you lifted your T-shirt to show the substance.. More precisely, the spots on the skin.. "... ..did you inject the substance into yourself?.. .you do understand that it's dangerous.." um, is he worried about you?.. Strange..
