Open the Twin Gate Championship
Dragon Kid turned heel on January 14, 2011, along with the rest of WARRIORS, when they attacked Masato Yoshino and World-1, and joined forces with Naruki Doi's group. On January 18 the new group was named Blood Warriors. On May 15, the rest of Blood Warriors turned on Dragon Kid and kicked him out of the group, despite the fact that he still held the Open the Triangle Gate Championship with CIMA and Ricochet. He then joined Masaaki Mochizuki's new stable, Junction Three, to battle his former group. As a result, the title was declared vacant. On June 19 Dragon Kid gained a measure of revenge on Blood Warriors, when he and PAC defeated Ryo Saito and Genki Horiguchi to win the Open the Twin Gate Championship. They would lose the title to Blood Warriors representatives CIMA and Ricochet on July 17. On February 9, 2012, Junction Three was forced to disband, after losing a fourteen-man elimination tag team match to Blood Warriors. After joining the Veteran-gun, Dragon Kid won the Open the Brave Gate Championship for the second time on May 6, defeating Ricochet. After a reign of 364 days and nine successful defenses, he lost the title to Masato Yoshino on May 5, 2013. He would go on to team with Oretachi Veteran-gun stablemate K-Ness to win the Open the Twin Gate Championship, and with K-Ness and Masaaki Mochizuki, won the Open the Triangle Gate Championship. He would suffer an injury later on, and would be forced to vacate both titles. On August 17, 2014, Dragon Kid and Masaaki Mochizuki quit Oretachi Veteran-gun to form a new stable with BxB Hulk, which on September 9, 2014 would be named Dia.HEARTS. On February 4, 2016, Dia.HEARTS was forced to disband after losing a match to Monster Express and VerserK. On April 7, Dragon Kid joined the Over Generation unit.
