is Do As Infinity's 22nd single, released on January 20, 2010. Of the four songs on the single, only the title track is new - the remaining three are the previously released songs "Fukai Mori", "Shinjitsu no Uta" and "Rakuen". The four songs on the single were all used as theme songs to either the Inuyasha anime series or the animated film ; the single was released as a commemoration of this. Four versions of the single were produced: a CD+DVD set in regular and first-print editions, and a CD-only release also in regular and first-print editions.[1] A music video directed by Wataru Takeishi was produced for "Kimi ga Inai Mirai".[2]
The lyrics of "Kimi ga Inai Mirai" include the song titles of the other three songs on the single.
