Strarf mentioned her being a Type 01... This probably means that Kaguya is supposed to be a prototype of some sort, but foreshadowing is still in effect here, so things aren't clear.
But if Kaguya stays in Tempesta form, an epic Ep 6 encounter is inevitable.
I love how in this anime, Shinki are able to fight outside the Game Center even without the ROG device. Besides, having the ROG appear here would make it reek of Yu-Gi-Oh...
My love for Harumi goes THIS far. Accomplished 2012/08/17.
