I'm pretty sure Haku is all "WTF?" because MEIKO is back. Anyway, since they're at Haku's candy store, it's only a matter of time before Luka reaches jealousy levels of over 9000.
Indeed. Either Meiko and Luka will have an ultimate battle to the death with Chibi Miku as the prize, or there will be a mutual understanding and twice the cosplay outfits for CM. Either way, we win.
