Your typical protagonist - a naive 16 year-old high school girl with a bit of an inferiority complex. Average grades, member of the track team, somewhat shy, neither particularly popular nor disliked by her classmates. Never dated a boy or engaged in any inappropriate behavior in her life. That is, until her sister ropes her into working in her eroge company as their new seiyuu. Reluctant at first, Kanna agrees to give it a try after a little emotional extortion. Much to her shock, she discovers she has a natural talent for erotic voice acting, which is further fueled by her embarrassment, lack of experience and overactive imagination. She resigns herself to pursuing a career in voice acting and always giving her best, no matter how unreasonable her co-workers demands get.
