Arata, Lilith and others in “Labyrinth and Magic Gunner”

Whoa, this is creepy, but kind of awesome.

Yeah, well it's always been a giant labyrinth, just not so spooky.

It's true, this is all Yui's magic. I get the feeling she's about to awaken.

Awaken? What, is she asleep too?

It's not like a normal sleep state. Yui is a kind of mage who lives in another realm, in a world of dreams. That's what her thema is about.
