Tessa

Disguised as Tessa, the Solver wore an astronaut helmet that was decorated with a small rainbow and smiley face sticker on the top right side of the visor. She also wore a JCJenson branded cap (corroborating her false affiliation to them) and a large, light grey bow on the right side of her helmet. Her outfit consisted of a short-sleeved, white crop-top-like jacket with a shiny silver leotard underneath. She wore a pair of moderately long white gloves that were yellow at the ends and silver pants with knee-high strapped boots. Finally, she had a golden name tag that showed her name and occupation, and carried a broadsword on her back attached with silver straps. To her left hip, she also has a pocket where she sometimes holds her revolver.

Personality Although Tessa was first seen as rather intimidating and mature during the ending of "The Promening", Tessa seems to be a very lively individual. This is demonstrated in "Home" where Tessa screams "N" in excitement and spins him around very energetically. This is further supported in "Dead End" where Tessa shouts "N! You remember me. (cough) Tall, handsome, air's toxic" in a similar vein to how she'd done in "Home". Given that the Absolute Solver masqueraded as Tessa with full intent to pass as her, it seems like this was one of her actual personality traits whilst she was herself.

She enjoyed fixing broken drones and giving them names and human hair, something other humans disapproved of. She was asocial, forming a emotional distance from other humans and instead creating her affinity towards drones. She didn't know how to interact with other humans and her only real friends being Worker Drones.

The way the Solver portrayed Tessa also seemed to be somewhat overly confident and proud of herself as she stated in "Dead End", "Human-made security this human can control!" with pride and confidence despite not gaining control over the Sentinels. Tessa also has a bit of an immature and rather childish personality that heavily resembles her past personality as a child, which yet again makes sense as this was what the Solver was exposed to.
