Arimura Ellen

Ellen (絵恋) is a tracer and a member of the Kamisato Faction.

Appearance
Ellen is a girl of short stature, with long black hair that reaches her entire height, dark-colored eyes and a pale complexion. She is dressed in an formal outfit similar to a butler's and wears an oversized lab coat with sleeves that cover her hands completely. The outfit is described as reminiscent of a ceremonial Japanese kimono.

Personality
Like the other members of the Kamisato Faction, Ellen's actions are directly in response to her dependence towards the faction leader. She has shown to be the more mischievous of Kakeru's three usual companions, willingly stepping into the men's bath to show her affection towards Kakeru, as well as interfering with the actions of her fellow members' own attempts to take his attention. Ellen is also the most prone to becoming a stalker of Kakeru because of her abilities as a tracer.

Although she does not seem friendly towards people outside of the faction, Ellen shows a degree of understanding towards the people Kakeru helps, although it would require that person to show willingness to be helped by Kakeru before she would act accordingly.

Abilities
Because she is neither a magician nor an esper, much of Ellen's activities as part of the Kamisato Faction involves using forensic science and chemistry in general in various applications. She has demonstrated her ability in using chemicals and reagents in unlocking doors, as well as claiming that she can use her know-how to perform an unofficial pregnancy test on the spot. Ellen takes pride in her abilities to the point that Kakeru himself does not think of getting away from Ellen, as any attempt can be made futile by her forensic tracking skills. However, she does show some limitations in her ability, particularly in analyzing unknown substances like pieces of Sample Shoggoth, which according to her would require a few days to determine its chemical composition.

Character Art Design
The designs for Claire, Ellen and Elza were created by Haimura using the concept of being "twisted in a galge-ish way". Very little was changed from Ellen's initial design except for her hair, lengthening it further so that it touches the floor.
