What's this? I thought the last arc wasn't over.

Season change? Maybe when the arc is ready the Akis will appear.

When we get cover pictures like this, they never seem to relate to the current arc. I suspect it's for a story from a while back that's just now going into print form.

Perhaps this would be for the arc where Lily gave her all to make breakfast?

I just reread this and I had forgotten how dang cute Lily is in it. So many reactions you don't normally see! Her (initially) slightly more adversarial relationship with Sekibanki is a refreshing change from her interactions with Kyouko.
