After the end credits, we see Caine (Donnie Yen) on his way to visit his daughter with a beautiful bouquet of flowers. As he makes his way through a city, we learn that Akira (Rina Sawayama) — Koji's (Hiroyuki Sanada) daughter and the former concierge of the Osaka Continental — has tracked him down.

She pushes her way through a crowd and, in an act to avenge her father's death, approaches Caine and unsheathes a knife before the post-credits scene cuts to black. But wait, does Akira kill Caine?! Unfortunately, it's unclear, but co-writers Michael Finch and Shay Hatten recently spoke with Polygon and said her "hunger for revenge" is the main point of the scene.

"One of the themes of this piece was to demonstrate the vertical reach of the Table," Michael said. "Because of the events that happen in the Osaka Continental, she goes in full force. What she doesn’t understand, and what we're trying to demonstrate, is that once you step into the Table, there is no stepping out."

He added, "She was locked in once Caine says, [...] 'I'll be waiting for you.' He knows that she’s going to come because she's part of the Table. [...] She's all in, she's gonna go after Caine for revenge. Her story is John Wick's story, in a lot of ways."

Shay told the outlet that the "cycle of vengeance and violence" is crucial to the franchise themes.

"It shows the cyclical and cruel nature of this world, that once you get in there, it is impossible to get out," he said. "I think that's why we empathize with John so much. No matter how many people he kills, you recognize, well, he didn't really have a choice. He fell into this life, and now he's just trying to get out and honor the memory of his wife. But it's a really challenging thing to do."
