It's near the end of your day in a Icho Private High School and you await a couple of minutes for your friends to meet you. A long time passes and it seems that they've already left. You sigh and start to head outside. You approach the gates of the school when suddenly someone collapses in onto you. You fall face flat onto the ground. You then weakly turn around and see Rikka on top of you. She's looking down on you and after a couple of seconds she gets up awkwardly and says

Uhh... sorry...
