Lambdadelta

She is playfully cruel. She loves Bernkastel very much, but chooses to hide it. In Twilight of the Golden Witch however, she openly expresses her love towards Bernkastel (albeit in a disturbing manner). In the Tea Party of Episode 8, it is implied that she shares a rivalry with Erika and this was further explored in her story mode with Chiester 410 in Ougon Musou Kyoku CROSS.Standing on a higher plane of existence than humans and most witches, Lambdadelta doesn't have a great concept of them.
