Seishun Amigo is Shuuji to Akira's first and only single. This single reached #1 in the Oricon weekly singles chart and is the #1 best-selling single of 2005 as well as the #3 single of 2006. Each song on this single was featured in a popular dorama; Seishun Amigo was the Nobuta wo Produce theme song, Colorful was the Dragon Zakura insert song, and Kizuna was the Gokusen 2 insert song. Colorful and Kizuna are sung solo by the actor featured in each specific dorama and Seishun Amigo is a duet.

The first press version included an exclusive 12-page photo-booklet, though interestingly didn't include the karaoke tracks. In 2005, the single sold 945,315 units. After 65 weeks in the Oricon chart, it sold 1,626,581 copies in total before dropping out of the top 200. The single was also released in Sweden, where it reached number 41 on the selling chart.

The single is certified Million by the Recording Industry Association of Japan, for a shipment of 1,000,000 copies.
