Kenny, now a villain, starts his succesful career in NJPW, while Ibushi also wins a lot... until he fights Aj Styles, the leader of the Bullet Club (Kenny's team). During the fight, Kenny betrays Ibushi, leading to his first big loss which will be the start of Ibushi's temporary retirement from NJPW.
Here he is, Kenny about to stop Ibushi from winning, not able to act, but his sad eyes and angelic hair are enough to distract Ibushi.
Ibushi moves to WWE (the famous American wrestling company), Kenny accuses WWE of stealing his ex.
Kenny keeps winning and finds out that now, even with his team (and he becomes the new leader) he feels lonely because winning doesn't bring Ibushi back.
Finally, in 2017 Ibushi comes back and decides to participate in a big tournament (called G1). Of course, Kenny participates as well and he is more than glad to have the chance to fight Ibushi because he is still angry (at him? at himself?). He only has eyes for Ibushi.
At the end, they don't face each others in the ring, but behind the backstage, after Kenny loses the last match. Ibushi seems to want to comfort him, but Kenny refuses and walk away.
