That’s Alisa and she pretty much is another Factory’s failed experiment. She was a pile of smoke. After meeting Marina she desired to become a human (I don’t know why though, Marina is as optimistic and kind as a brick). So she came to the Factory and asked them to make her a human being. And they compressed her. And everything was fine for some time. Now Alisa has some sort of anisocoria and heterochromia and breathes some rainbow smoke out from time to time.

She hangs out with Blot and Marina often. People person, GSOH.
