Whats the song? It's a japanese anime ending song...?

It's a japanese song, and I know its an ending song to the anime Bleach. I do not know what season. It is sung by the charecter Oriheme. It goes something like, (english translation) I can't write a song with honest lyrics, because I always wind up sugar-coating the words." Then later, In japanese, it says "Ikanai SKY CHORD" and then something in japanese, and on the same line it says "Sky cord" again. Any clue what this song is called, or at least what season it is from?
