Sakuranbo Theatre Group (劇団さくらんぼ,Gekidan Sakuranbo?) is an entertainment talent agency, which specializes in training child voice actors. Rin Kohana is the only known voice actress of this agency working with an Unnamed Manager.
If they have the time, the managers always go observe their voice actors or voice actresses when they work to give them advice. In many cases such as Rin's, her manager is both her manager and voice acting teacher at the same time. This agency doesn't have the assessment system like Aozora Productions.
