Sonsi is a rapper whose debut album Nisemono and RAPSTAR 2025 appearance have led to a run of releases and a two-man live. His next confirmed date is a November 26 show with BABYWOODROSE at Shibuya WWW X.
Sonsi's rise runs through the audition program RAPSTAR 2025. That appearance is the origin point for the four stories here: the beat he used on the show came from STUTS, and the relationship carried into his released work.
His debut album Nisemono arrived with the track Omoidoori, produced by Koshy and STUTS. The music video, directed by Kazuki Ito, was released in July. Weeks later, on July 29, Sonsi and STUTS released BBA Spice, a studio version of the song he performed on RAPSTAR 2025 with an added second verse and STUTS handling arrangement and mixing.
The most recent story puts Sonsi on a two-man bill with BABYWOODROSE at Shibuya WWW X on November 26. The show is part of the XX series run by Shibuya WWW, with tickets at 4,000 yen in advance and a lottery reception that opened September 18 at 19:00 and closed September 25 at 23:59. The pairing places him alongside another recent headliner, BABYWOODROSE.
