If Raiden knew he was sparring with Kaylin, there would be many questions being asked already. Instead, Raiden pauses just inside the doorway when he's greeted, giving Minoru a bow from the waist, one hand clasped gently over a loose fist in respectful greeting.

"Of course. I would not miss this." There's that strangely familiar smile, and Raiden's eyes glow a little brighter as he straightens again, walking over so he was beside Minoru.

"How would you like to begin?" They could certainly go straight to sparring with Jutsu, but they certainly had time with so many people planet-side taking demand off the holodecks. They could provide each other a demonstration, or try a match without using their abilities (which would be more difficult for Raiden, but do-able). Raiden had brought no expectations, just glad to be having the opportunity.
