More about Mahiro Oyama
Mahiro Oyama is the title character of Onimai (Japanese: Onii-chan wa Oshimai). Mahiro lives as a withdrawn otaku until his younger sister Mihari turns him into a girl with an experiment. From then on, he grows into the role of the little sister.
The source material is by Nekotofu, who began publishing the manga online on Pixiv in 2017; it has run in Ichijinsha's Monthly Comic Rex since 2019. The anime adaptation by Studio Bind aired from January to March 2023.
The figures show Mahiro in different appearances, from the Nendoroid to the 1/4 statue in the NEET T-shirt. A further version, Heisei Gyaru, has been announced.
