It takes about a minute after Riku says that for Eiko's mind to finally comprehend what was going on, and she bolts upright in her chair. She surveys the room and sees that, suddenly, she's more awake than everyone else. The information on the board is nothing new to her, and the teacher was just grumbling his way through the material half-heartedly. Something catches her eye out the window on the classroom's door, and she sees the back of Riku's head going away from the room. Deciding to follow, she quietly packs her thing and sneaks out of the room as well. But, when she gets out there, she can't see him anywhere... where'd he go?
