Is Dr Amamiya from the (a lot of adaptations, originally a hentai) Sakusei Byoutou, (the manga adaptation was hit by the DMCA due to being from Kodansha) I think this specific image comes from a collaboration in a game, I think @AnonymousContributor has a profile post about this... alright it was from the original CG
🤓☝️ Erm akshually its from this art for the all ages version because the CG has a rather.... Unique art style. The thing I was saying from the CG was the image in the comment section. Amamiya's modified defibrillator is used in the main story against herself by Mia.
