This. This sort of thing is exactly what Marik's been wanting since reconciling with the Pharaoh. To enjoy life. Something as simple as a water fight is a new and exciting thing to him. He doesn't even care that the force of the water knocks him backwards fully into the river again.

He kicks his feet, trying his best to splash Kaiba with whatever ounce of water he can, all while laughing his head off. Which is in turn making him almost too weak to fight back.

"King, help me!"

Meanwhile Usi's just watching this all unfold from the riverside, shaking his head.

His trainer is insane, clearly.
