Here’s my idea, and it actually works within the them.

Let me set the scene for you:

Two buddies, Ken Rondle and Ken Koratsu are returning to their apartment with a super-large Pizza from the Pizza Hovel up the street.

However, the manager of that shop knew that both Ken and Ken are martial artists, and thus stuck a medium meat gluttons’ pizza in the box for them to fight over.

And fight over it they shall!

You take the role of Ken Koratsu as he tries to win the second pizza, even if that means beating the hell out of his best friend! (Though this is nothing new for them, they often fight over food. Not the end of the friendship or anything)
