Klein

was Dr. Mobius's personal lab assistant and the closest person to understanding the doctor. As a workaholic and amiable to any request from Mobius, Klein was always busy and buried under mountains of work. However, when the 10th Herrscher spawned in the Previous Era, Klein was subsumed as one of its 1000 individuals. 
== Appearance ==
As a human, Klein was seen wearing a heavy white-green lab coat and black lab pants. Her hair was short and pale green with an ahoge, with one strand of hair between her eyes and one long tuft of hair stemming from the ahoge to drape over her left face. She is often seen with pinkish-green-hued eyes with an impassive expression.
== Personality ==
Klein was an incredibly hardworking individual who often came off as impassive towards her ever-increasing workload. That said, despite her long to-do list, it doesn't stop her from taking more requests even if it doesn't fall within her scope as a lab assistant, as she couldn't say no to such orders, particularly Mobius's. 
== History ==
Klein was an assistant to Dr. Mobius and she was one of the few people who could truly understand her. However, Klein had become a part of the 10th Herrscher and managed to murder Mobius. Su found Mobius' body lying in a pool of blood and immediately managed to subdue the nearby Klein since he didn't want to kill her. Meanwhile, a physical manifestation of a shadow had sprayed out of Mobius' body and devoured both Klein and the Herrscher core, much to Su's shock, which supplied enough energy for Mobius to resurrect. Su regrets this event deeply, as he thinks if he hadn't been suppressing Klein at that moment she might've had a chance to become human again.
Later, Mobius recreated Klein as an ELF.

==Speculation==
* Klein is most likely named after Felix Klein, a German mathematician who devised the Klein bottle, a 3-dimensional Möbius strip.
* Klein is probably based of Yssring Leavtruth, a scientist from Houkai Gakuen due to the similarities in appearance.
