Kei loves stories, but I guess he isn't too fond of this one...

The two start making their way down the corridor.

Taku: "So what's that cursed mirror supposed to be?"
Kei: "Sensei found it in the cellar a few weeks ago and moved it upstairs. Ever since then, rumors started going around."

The mirror is shown, tall and with a round jewel at its top.

Kei: "I've never seen it myself, but apparently some people witnessed the surface distort and show a strange place. A messy room in some destroyed house underneath an ominous red sky..."
Taku: "I think I've heard similar stories about mirrors like these somewhere else."
Kei: "T-There are more of them?"
