The dark witch (has not debuted), with a delusional nature. Her power grows as the darkness deepens. In total darkness she can scarcely be matched. She's almost unrivaled inside an absolute black; however, with lights as numerous as they are nowadays, she is not a witch to be feared.
The dark witch's minion whose duty is to dream. She can shapeshift into anything to express her witch's desires in pitch-black darkness. She boasts incredible power in the dark, but something as small as a lamppost or moonbeam can halve her strength.
- Sketches from the Production Note show her as a star with several arms.
- Suleika is a German form of the name Zuleika of arabian origin that means fair; brilliant and lovely. It was made popular in Germany by the poem collection West-östlicher Divan by Johann Wolfgang von Goethe.
- Ulla is a nordic name that means will, determination. In German-speaking countries, Ulla is a variant of the name Ursula of Latin origin that means little she-bear.
- Before it was disproven, it was speculated that Suleika was the Witch from the dream in episode one. It is now known that that witch is Walpurgis. This may have been because her head looks like a similar shape to Walpurgis' Gear or because it was very dark.
