'Yazawa Riko' (矢沢 リコ Yazawa Riko) is one of Hanzou Gouda's gang members and a supporting character of Ban's friends in Danball Senki.
Riko, Kinji and Tetsuo challenged Ban, Ami and Ryuu to an LBX battle to let them pass and see Gouda. Despite Ban and AX-00's compatitable play, Riko's team had the advantage with Mad Dog's invisibility, but they were defeated thanks to Kazu's timely arrival.
They reappear when Takuya scouted them to join Seeker. Riko watches over the sidelines and cheer on Ban for his never-giving-up enthusiasm.
