Acting style and philosophy
Koichi has a background in theatrical acting, which she credits as a major influence on her voice acting performances. In a May 2026 interview, she noted that her stage experience allows her to better understand character blocking and emotional resonance even when behind a microphone. Known for voicing young male characters, Koichi explained that her approach focuses on adjusting her breathing patterns and vocal energy rather than just lowering her pitch. She emphasizes the importance of raw emotional delivery in action sequences, often physically engaging during recording sessions to capture the intensity of her roles.
