Err...is that a football? 3nd panel bottom-right corner

Yeah, that's a football. Between that and the kettle (used for holding drinking water), we're meant to see Keine as a coach's assistant or some such. It's a staple that I've seen a few times before, though the only example I can remember offhand was in Full Metal Panic? Fumoffu.
