Manami Toyota
On June 11, Tsukushi broke her own record for the fastest win in Ice Ribbon history by pinning Emi Sakura in four seconds. The following day, Tsukushi wrestled at an event produced by the "Jungle Jack 21" stable, facing the group's leader, "joshi" veteran Aja Kong, in a losing effort. In a post-match interview, Kong praised her young opponent, comparing her to "joshi" legend Manami Toyota. Tsukushi received another shot at the ICE×60 Championship on June 19 at "Teens.III", but was again defeated by Tsukasa Fujimoto. On July 10 at "Yokohama Ribbon", Tsukushi was defeated in a singles match by freelancer Manami Toyota and was afterwards once again praised by her opponent, who had a 23-year experience advantage over her. Tsukushi and Toyota had a rematch on August 21 at "Fushigi no Kuni no Ice", where Toyota was again victorious. On September 16, Tsukushi attempted to regain the IW19 Championship, but was defeated in the finals of a tournament for the vacant title by her old training partner Kurumi. On September 24, Tsukushi teamed with Manami Toyota in a tournament for the vacant International Ribbon Tag Team Championship. After defeating the team of Kurumi and Ray in the first round and former champions Muscle Venus (Hikaru Shida and Tsukasa Fujimoto) in the semifinals, Tsukushi and Toyota were defeated in the finals by Ice Ribbon's rival promotion Sendai Girls' Pro Wrestling representatives Dash Chisako and Sendai Sachiko.
