This is essentially the normal experience from the original version of the game, except with chibified sprites.

This is an event match. The player is presented with various scenarios. Some of them are based on other Kunio games of the past, such as Dodgeball or Soccer.
This allows the player to browse through a collection of Kunio art produced over the past 25 years.
