STEREO DIVE FOUNDATION and NANO joined forces to create and perform "Dream Big," DoKomi's inaugural official theme song, at the German anime convention's opening ceremony on May 29. The track dropped on digital platforms the same day, followed by the artists' live debut performance during the opening festivities.

The collaboration extended throughout DoKomi's run in Düsseldorf. On May 31, both artists held separate concerts on the convention's main stage before reuniting to perform "Dream Big" together. NANO performed alongside guitarist Shin, taking time to connect with the crowd by asking longtime fans to identify themselves—a moment that visibly moved the artist. "It felt like being a parent watching their child grow," NANO reflected on the enthusiastic response from fans who had attended his previous DoKomi performances in 2013 and 2015. He later left the stage to interact directly with attendees, holding hands with fans throughout the performance.

STEREO DIVE FOUNDATION's solo set showcased his extensive anison catalog, with animated backdrops of opening sequences and iconic anime scenes accompanying his performance. He also surprised the audience by addressing them in German, drawing from his childhood spent in Frankfurt.

After STEREO DIVE FOUNDATION's performance, NANO rejoined him to perform "Dream Big." As the event's closing act, DoKomi projected the song's newly unveiled animated music video, which featured convention attendees enjoying various activities and scenes throughout the festival. NANO, who served as the track's lyricist, also shared the full lyrics on X (formerly Twitter) following the premiere.

DoKomi, shorthand for "Doitsu Komikku Maketto" or "German Comic Market," stands as one of Europe's largest anime conventions. The Düsseldorf-based event draws fans interested in anime, manga, cosplay, gaming, music, and broader Japanese culture, making it a key platform for anison artists to connect with international audiences.
