~English Lyrics~

[Maka] I gaze up at that shining moon high up in the dark, ah~, mauve painted sky
[Soul] The souls that havent disappeared have become disturbed and restless, So, they are shouting

[DUET] Our destinies have crossed into that darkness, but
[Maka] When I grip tight [Soul] and it feels right
[DUET] we resonate with each other, shake up! shake up!

[DUET] The wavelength that we create, keeps us in Soul Style
[Maka] I want to protect...

Mauve-iro no Sympathy is a song sung por Maka's and Soul's voice actor.
So basically, it's their character song. :3
