NPC: Am I daydreaming, or did someone just actually walk by with a piano with barbecue grills?

That person looks a lot like the girl who used to be in your department. You know, the one with long, beautiful black hair...

Based on some NPC dialogue and also shown in a short animation (post #10778020). Chisa (from the Startorch Academy Department of Engineering) had a piano with barbecue grills and wheels. Truly right at home after being freed from Honami City.
