Kohaku studied the Riolu. "You may come if you want, it's your choice alone. No one should be forced against their will, you know," Konoha says to the Riolu, "I'm from the past though, and I'll be going back after I get strong enough... but who knows. I'll most likely come right back. Everyone here I've met so far, well almost everyone has been so kind to me." Konoha didn't forget about the Mikado person who came after them.
