ARC SYSTEM WORKS and PlayStation announced that Tōkon would launch with 20 playable characters — but there are actually 21. The Champion, the main antagonist of the story, is a hidden playable character. Here is the fastest way to unlock them.

Once the credits roll, you will get a message that the Champion is available to select as a playable character.
💡 Tip: expect roughly 20 minutes for a full Episode Mode story when skipping cutscenes — an easy unlock for a secret character.
