Kaosusōsa Eris

**Eris Kaosusōsa (*カオス操作 エリス* *lit. Kaosusōsa Erisu)*** is an exchange student living with the Saiki's as a host daughter and the fourth psychic introduced in the manga/anime. She is love-interest of Aren's and the second prettiest girl in the series, second to Kokomi. Eris is one of the few non-family members that knows about Kusuo's powers along with Reita, Mikoto, and Touma.

## Appearance

Eris is a beautiful girl with exceptionally good looks and a petite figure, though she hereself admits that her looks are beneath Kokomi's. She has an lean body with long, flowing lavender hair that reaches about her lower-back, her bangs typically hand over her right eye covering her heterochromia but after her talk with Aren she doesn't covers it as often. Her right eye is gold and her left is a burgandy red. Eris is mostly seen adorning a headband or a magenta bow, and a pair of dangling gold earrings in the shape of small spikes.

In school, she wears the PK uniform that a standard female student wears, a long-sleeved shirt with a ribbon on her chest, and she wears a green skirt with black stockings on her legs.
While on days off, she sometimes styles her hair down in two long low pigtails worn over the front of her shoulders, and held with hair ribbons. Eris' casual wear is a white hoodie with black sleeves. Appearing slightly too big for her, the sleeves cover her hands and there are pockets in the waist area as well. She also wears tight black leggings that cover her legs entirely, with black boots.

## Personality

Eris is introduced as an aloof individual, interacting minimally with her classmates and being described by Kuniharu as a robot. Similarly, Eris has a remarkably collected, able to keep her composure in the midst of confrontation. She is incredibly polite and kind towards others, offering to help anyone she trusts at the moment. She is protective of her friends, usually being more docile when dealing with agresors but she has no trouble defending her friends with extreme violence. After moving in with the Saiki's, Eris becomes more expressive and opens up to her classmates, showing her more sarcastic, apathetic attitude.

She loves teasing others and is quite dry-humored. Eris generally tends to smirk before teasing or performing her antics towards others, delighting in placing them in uncomfortable situations. She can be proud and facetious but has a nice, joyful and cheery part of her. With the possibility raised upfront, Eris does not shy away from displaying a manipulative side. She can be rather strong-minded when it comes to messing with others but almost always follows Kusuo's orders, out of respect and care for with wisdom and wishes.

Eris is shown to be insecure about herself and her abilities, believing she is not good at anything apart from running or cleaning, and she constantly worries that she's not being a good friend and host daughter. Wanting to prove her worth, and to refrain from reverting to her old habits, she tries to do all the chores, such as cleaning, dishes, cooking deserts, etc. After failing to use a stove multiple times, she tries to be more of a normal "sister" to Kusuo by baking him as sweets and making coffee jelly and asking Aren for cooking lessons with a stove. Eris shows surprisingly little emotion when discussing her sister's death, suggesting an emotional detachment to people she knows. While she may also keep her friends away at an arm's length, she greatly respects Saiki's resolve and feelings toward his family & friends so she acts to help him.
