White Len
白レン
Apparently, she was created from the remains of Zepia Eltnam Oberon by Aozaki Aoko and has taken in Len’s suppressed personality. Her abilities are the combination of those of original Len (dream manipulation) and TATARI (creation of illusions from rumors).
She also inherited from Len the nature of a familiar and the need to have a master in order to stay alive that comes with it.
