"Diver" is the eighth single by Japanese rock band Nico Touches the Walls, released on January 12, 2011, from their third studio album Passenger.

[2] At the request of fans, the band brushed up the song, rearranging it after its initial concert version and presented it as the opening theme for "Naruto Shippuden".

The coupling track, "Yuujou Sanka", has only been performed once, at NICO's first ever one-band show, and the song had nearly disappeared.

It's an innovative song, filled with memories from Mitsumura's (vocal, guitar) own school festival.

The bonus tracks were recorded at CC Lemon Hall, on October 7, at the 2010 concert "EastxWest Apollo and Luna ~Night of Luna~".
