is the eleventh single by Bump of Chicken, released on November 23, 2005. The title tracks are from the album Orbital Period. "Karma" was used as the opening theme for the video game and animated series Tales of the Abyss.
RPGFan noted "Supernova" as "a very nice song" that has a "simple but pleasant melody with soft vocals". They liked "Karma" more and said: "It has a very solid melody that I was instantly engaged in, and a very good vocalist to complement it."
All tracks written by Fujiwara Motoo.
