Naito countered and Styles then focused on attacking Naito's left leg. Styles later applied the Calf Killer, forcing Naito to grab the rope to break the hold. After another Styles Clash attempt, Naito countered by throwing Styles over the top rope to the floor. When Styles returned to the ring after a 19 count (NJPW employs a 20 count in their matches), Naito attempted a top-rope huracanrana. Styles blocked it, converting it to a Styles Clash from the second rope before pinning Naito for another Bullet Club victory at 14 minutes and 25 seconds. Main event matches Wrestle Kingdom 9 featured two main event matches. In the first, Shinsuke Nakamura defended the IWGP Intercontinental Championship against Kota Ibushi. Ibushi ridiculed Nakamura and used several of the champion's moves, including the corner vibration boot, the reverse powerslam, and the Boma Ye knee strike. Nakamura, responding aggressively, kicked out of the latter at one. Nakamura used a variety of knee-based strikes, and Ibushi's attacks included a standing corkscrew moonsault, a roundhouse kick, an elevated sit-out powerbomb, and a double stomp to the chest. Ibushi also jumped on the top rope, grabbing Nakamura on the apron, and German-suplexed him back into the ring for a two count. In the finishing sequence, Ibushi got up immediately after receiving a knee from the second rope to the back of his head; both attempted the Boma Ye, but Nakamura recovered first with the Landslide and then the Boma Ye knee to retain the title at 20 minutes and 12 seconds. After the match, the wrestlers bumped fists. In the second main event, Hiroshi Tanahashi defended the IWGP Heavyweight Championship against Kazuchika Okada. The challenger controlled the early match with a hanging DDT onto the floor, a Heavy Rain (Death Valley driver) on the entrance ramp, and the D.I.D. submission. After they battled on the top rope, Tanahashi missed a High Fly Flow but countered Okada's Rainmaker. The momentum shifted to Tanahashi as he performed a dragon screw legwhip and continued attacking Okada's leg. Tanahashi later dove off the top rope and over the guard rail with a High Fly Flow crossbody to Okada on the floor outside of the ring. After Tanahashi tried another High Fly Flow crossbody back in the ring, Okada rolled through for a Tombstone piledriver, which Tanahashi countered with his own Tombstone. Although Tanahashi landed a High Fly Flow to Okada's back
