This is the 1st EP that marks the opening of a new chapter for Lenny code fiction, who have reached the 10th anniversary of their debut. Wataru, the frontman of Lenny code fiction, has continued to travel around the world and to post the records of those travels on social media, and now has more than 130,000 followers on Instagram. This is a conceptual EP in which the things Wataru has seen at first hand and felt in person are recorded in the lyrics and sent out by the band. The Regular Edition is planned to contain six songs in all, including "Episode 1 (Dai Ichi Wa)", "Sekai Isan to Yoru" and "Shushin" (subject to change).
