STEREO DIVE FOUNDATION and NANO brought their collaboration to life at DoKomi in Düsseldorf, Germany, debuting the convention's first-ever official theme song, "Dream Big." The track released on digital platforms on May 29, coinciding with the opening day of Europe's biggest anime gathering.

The partnership between the two artists came together last year when DoKomi confirmed both as co-producers and performers of the anthem. On opening day, they performed "Dream Big" during the convention's ceremony, setting the tone for a weekend of celebration.

Two days later, on May 31, both artists took to DoKomi's main stage for individual showcases. NANO performed alongside guitarist Shin, reconnecting with long-time fans—he noted a particularly emotional moment when asking attendees who'd seen him perform at DoKomi in 2013 and 2015. The artist even left the stage to interact directly with the crowd, sharing personal moments with fans.

STEREO DIVE FOUNDATION's solo set featured a full-screen celebration of anime, with video backdrops of opening sequences and iconic scenes playing behind him as he performed classic anison tracks. He surprised the audience by addressing them in German, drawing on his childhood spent in Frankfurt.

After his set, NANO rejoined STEREO DIVE FOUNDATION for a joint performance of "Dream Big." As a finale, the convention screened the song's newly-released animated music video for the entire crowd. The visual captured the spirit of DoKomi itself, animating attendees enjoying various convention activities and moments throughout the event.

NANO, who wrote the track's lyrics, shared the complete lyrics on social media following the performance. The collaboration highlights the growing connection between Japanese anime musicians and Europe's passionate fan communities, with DoKomi serving as a gathering point for both creators and fans across the continent.
