Image song

In Japan, an image song or character song is a song on a tie-in single or album (often called an image album or character album) for an anime, video game, drama, manga, or other commercial product that is sometimes sung by the voice actor or actor of a character, in character with harmonies. It is meant to give a sense of the personality of the character. Character songs are considered an important part of an anime or drama's success, as they often provide insights to a character that may otherwise go unexplored on the program itself. The series' creators may also include details about a particular character's design stages and evolution, and on occasion even design sketches so fans can see for themselves how a character changed.
