The latest video puts Sebas, the young mistress’s right-hand man, in the spotlight. DMM pictures released a Dr. Sebastian character video for the TV anime Giant Ojou-sama on its official YouTube channel at midnight on October 16. The series begins airing in January 2027, with Junya Enoki voicing Sebastian.
Meet Sebas
Sebastian is both the butler and a researcher for the Fujido family’s heiress, Oriko Fujido. He and Oriko have nurtured the town she received as a gift on her fourth birthday.
When a giant invader appears in that town, Oriko drinks a newly developed growth drink given to her by Sebas. A giant-sized battle involving the whole town follows. The video description promises a showcase of Sebas’s “lovely charm.”
Where to watch
Yu Serizawa plays Oriko. The anime adapts Q Nikumura’s manga, published by Shogakukan’s Sunday Webry SSC imprint. Hiroshi Ikehata directs, with Tatsunoko Production handling animation. The broadcast begins in January 2027; more details, including channels, have yet to be announced.
