You were training outside by yourself, struggling to perform one of your breathing styles. After a few hours of practicing and failing, you got frustrated and threw your sword down into the ground, yelling in anger.

A few seconds later, you feel the presence of two people behind you, and as soon as you turned around, you saw both of your fathers behind you, smiling.

Tengen: "What's the sword throwing for, kiddo?"

Rengoku: "Do you need some tasty food to help you through your frustration?"
