On November 3, 2020, at Ultimate Party 2020, Yuki Ueno became the 4th DDT Universal Champion by defeating Chris Brookes. After successfully defending it for the second time on January 9, 2021, he asked for his next challenger to be Yukio Sakaguchi, from whom he said he learned a lot in the past year. Sakaguchi accepted the match, then, in the backstage interview that followed, snuck up behind Ueno and applied a sleeper hold to choke him out.[4]
On December 21, 2020, the KO-D 10-Man Tag Team Championship was vacated and renamed "KO-D 8-Man Tag Team Championship" due to the difficulty of scheduling a proper title defense during the pandemic.[5] A title match was immediately announced for the Kawasaki Strong 2021 event in which a team led by Sanshiro Takagi would face a team led by Shinya Aoki.[6] The remaining participants were later announced one after another. Takagi and Aoki had previously been fighting over the DDT Extreme Division Championship with Takagi finally winning the title and ending Aoki's 237 days reign (the third longest in the title history) at Ultimate Party 2020.
On January 3, 2021, at the New Year's Day special show, Yuki Iino, a member of the All Out stable who was scheduled to return from an injury at the Kawasaki event, angrily confronted Yuji Hino who had returned to DDT on December 23 and aligned himself with the rival Damnation stable. A singles match between the two was scheduled for the February 23 event and Iino return match would be an eight-man tag team match pitting All Out against Damnation.[7]
The second match of the evening saw the team of Shinya Aoki, Super Sasadango Machine, Antonio Honda and Kazuki Hirata win the vacant KO-D 8-Man Tag Team Championship. In the closing moment, Hirata's signature dance routine caused the lights to go out. In order to restore power to the venue, Danshoku Dino offered to use his "anal electricity" as a power supply, but the extension chord brought by assistant producer Hisaya Imabayashi was too short to reach the ring. One by one, the competitors each gave a speech regarding the importance of sacrifice and joined a human chain connecting Dino's behind to the chord. With the power back on, Hirata was able to perform his dance routine but this caused Dino's power to run out. Finally, Aoki offered to use his own "anal electricity" power, Hirata was able to finish his dance and then pinnedSanshiro Takagi for the victory.
Next, Saki Akai and Maya Yukihi faced Saori Anou and Miyako Matsumoto. Annoyed by her partner's antics, Anou performed a fisherman buster on Matsumoto. This allowed Akai to get a pinfall victory after executing the "Rookie Award" on Matsumoto. Akai, Yuhiki and Anou then posed all together for the photographs and quickly exited the ring when Matsumoto tried to join in.
The penultimate match was Yuki Ueno defending the DDT Universal Championship against veteran Yukio Sakaguchi. Ueno executed a "WR" (a modified "Ranhei") but wasn't able to get a pinfall out of it. Sakaguchi went for a Sleeper Hold but Ueno reversed the hold. The referee called for a technical knockout and awarded the victory to Ueno. Following the match, Sakaguchi got back on his feet and handed Ueno his title belt himself as a mark of respect.
