kubik:3

A black cube with a white rectangular door rotates against a dark background with glowing orange particles, revealing a white light from within. The scene cuts to a close-up of a silver-haired anime character with glowing eyes, then to a view from inside the cube looking up at a pink-haired anime girl, followed by a shot of the pink-haired girl and two other characters in a classroom setting, and finally back to the interior of the cube showing the silver-haired character's face looking up.
