Why wasn't it the first thing you thought?Why was paizuri one of the first thing you thought?
Arika said that the drug is temporary so Mahiro will go back to normal and she pulled out a hair regrowth drug so there will be no change to his appearance. Neko also said that he'll draw him as normal next time.Anyway, it would be so funny if in the next chapter Mahiro doesn’t revert back to her original body and just stays like this until the end of the manga, lol.
