Character Song

This thread is for posting your favorite character/image songs.

Q: What is a character/image song?
A: It is in a form of either a single or album (image album) for anime, game, or dorama (television drama) that ties in to the character portrayed -- usually sang by the voice actor/actress playing the character. It is to give a feeling of personality for that character.
There may be another form where the voice actor/actress sings a song that is aired in the series that then becomes their version (i.e. opening/ending song).
A character song may be about the character, but may not be sang by the voice actor/actress.

With that said, I'll start first! When posting, please give Anime Name, Song Name, Character Portrayed, Singer Name (plus role if any), and last but not least, the Song :>
