A man who calls himself Hakase (professor) works in top class A.I. engineering. He wishes to create the perfect android and he wants to use the beautiful male model Hinatsu as a base. But Hakase becomes a bit too obsessed with the real Hinatsu during his investigations. Hakase is very perverted and does many strange things to learn anything and everything about Hinatsu. Hinatsu wants nothing to do with this nut job and just wishes to look after his little sister. But Hinatsu seems to get dragged into Hakase's messes and trouble keeps on coming their way! In 2023, Eri Sakondo (the mangaka) confirmed that Hakase Ga!! was cancelled after its editor stopped editing manga and Hakase Ga!! was too wild to be handled by another editor. In that same statement, Eri Sakondo also confirms that Hakase Ga!! is a spin off of Kousoku Eiji and that both mangas take place in the same world.
