"Yes!" Tobirama agreed as Madara panted, catching his breath from the dizzying whirl and immediate shouting. "This is not quite as planned, however. . ."

"Your 'something new' was a completely untested hiraishin experiment?" Madara demanded, stiffening, and glared as Tobirama confirmed it with nothing closer to an apology than a shrug, then waved him off, wandering a few steps away.
