Studying for Chemistry. Best way to describe it is like leveling up for a final battle.
Furthermore, there’s a song from DDR Konamix that’s also in Zone of the Enders! While I never thought of DDR having/sharing music from/with ZoE, it seems painfully obvious once I notice they’re both by Konami. :P
I’ll find out the name of the song tomorrow, when I can legally (according to my parents) play the thing… because school will be out.
