Cooking of any sort was always a welcomed pass time for Rin. Especially when it replaced time that normally was forced dedicated to studying class material. In fact he's got a rather sing songish gleam about him once inside the home-ec room.

"You may be a genius with books but as far as the kitchen's concerned you sure are a dunce eh Yukio? Lessons on how to make sushi??" Rin snickers, obviously letting the simple request go straight to his ego without understanding the underlying intent his twin had.

"It's a pretty simple dish, but that's what big brother's here for, you'd be lost without me."
