Japanese voice-over performers
SEGA lists these performers separately under “Voice Over,” in a Japanese-language context: Taishi Nakagawa, Koichi Yamadera, Subaru Kimura, Ryo Hirohashi, Yuichi Nakamura, and Marina Inoue. The release does not pair each performer with a character, so it does not support assigning individual roles.
