30-Sai Made Doutei De Itara Mahou Shoujo Ni Narimashita

I always believed the internet joke that "if you're still a virgin at 30, you'll become a wizard," but I never thought it would happen to me. Except, I didn't become a wizard, I became a magical girl? And to make it even crazier, I used to be an old virgin guy! This comedic manga tells the story of how a group of old virgins transform into magical girls. It was so well-received that it was even nominated for the Tsugimanga 2020 Award in the Web Manga category.
