The second season of The Devil is a Part-Timer! anime is set to release in July, 2022, so I thought now would be a great time to look at the actor who voices Sadao Maou in the hit series.
Especially because it has been nine years since the release of the first season of the series, and the same actor will be back to reprise his Sadao Maou role in Season 2.
An actor who, by the way, has had a more than decade-long career so far, and played popular roles in many hit anime series.
Who voices Sadao Maou in The Devil is a Part-Timer!
The Japanese voice actor who plays Sadao Maou in The Devil is a Part-Timer! is Ryouta Oosaka (aka 逢坂 良太, Ōsaka Ryōta).
Oosaka was born in Tokushima Prefecture on August 2nd, 1986, which currently makes him 35-years-old.
He became interested in the anime industry when he moved to Tokyo with a friend who planned on training as a voice actor.
Oosaka enrolled in a voice acting school himself and, once he graduated, joined the Early Wing talent agency (see his agency profile page, and listen to some of his voice samples, here).
An agency he is still affiliated with today.
Ryouta Oosaka’s first anime role was as Palmo in Kimi to Boku.
He went on to play Kanzai in Hunter x Hunter, and Atsushi Kanamoto in Sword Art Online. His first main role was Yuki Sanada in Tsuritama.
