On that same show, Kiyomiya participated in a battle royal, which was eventually won by Takashi Iizuka.

On January 9, 2017, Coming of Age Day in Japan, Kiyomiya unsuccessfully faced Takashi Sugiura in a singles match, however, afterwards, Sugiura, impressed with Kiyomiya, offered him a handshake and the chance to form an alliance. Kiyomiya accepted, stating that he is ready to take the next step in his career, aligning himself with Sugiura and turning heel in the process. The following day, Kiyomiya debuted a new all black ring attire along with a more vicious ring style and ruthless attitude in a loss to Hi69. Kiyomiya, now a fully fledged heel, teamed with Sugiura on February 24 to defeat GHC Tag Team Champions Kenoh and Masa Kitamiya after Kenoh turned on Kitamiya to align himself with Sugiura and Kiyomiya.

Afterwards, Kiyomiya was named as Kenoh's first challenger for the GHC Heavyweight Championship. Kiyomiya lost by knockout on January 6, 2018. After the match, Kenoh and Takashi Sugiura turned their back on Kiyomiya, attacking him, but he was saved by the whole NOAH roster, specifically Go Shiozaki, who helped him to the back, turning Kiyomiya face in the process. On April 11, Kiyomiya and Shiozaki defeated Kenoh and Takashi Sugiura to win the 2018 Global Tag League. A few weeks later on April 29, the two defeated The Aggression (Katsuhiko Nakajima and Masa Kitamiya) to win the GHC Tag Team Championship, but lost the titles back to them exactly one month later on May 29.

From October 30 to November 25, 2018, Kiyomiya participated in his first Global League since 2016 where he finished with a record of four wins and three losses to advance to the finals, where he was originally scheduled to face Naomichi Marufuji, however, Marufuji was forced to pull out due to injury and was replaced by runner up Katsuhiko Nakajima. Kiyomiya defeated Nakajima in the final to win the 2018 Global League.

On December 16, Kiyomiya challenged and defeated Takashi Sugiura to win the GHC Heavyweight Championship for the first time in his career, making him the youngest ever champion in the process at the age of 22. Kiyomiya made his first defense against Kenoh, on January 6. Masa Kitamiya won a Number One Contender match against Atsushi Kotoge on January 20, but was defeated by the Heavyweight Champion on February 1. After the match, Naomichi Marufuji came to the ring and challenged Kaito Kiyomiya, and the champion accepted. The match happened on March 10, in the new ring, and Kiyomiya successfully defended his title.
