Haley Holst

 (Up-to-date as of DISCO 1: September, Part 1)

Haley Holst is a senior student at Newcastle County High School in Eidolon DISCO. She is a founding member of the Mystery Solvers' Club. Her Eidolon is Shining Star, a Wildcard that can take various forms and abilities.

Personality
Haley is curious and harbors a deep passion for science and astronomy (and horses). She greatly values being intelligent and good at school, with her greatest fear being mediocre. She puts her all in everything she does, whether that be homework, her part-time job at Martha's horse ranch, or her membership of the Mystery Solvers' Club.

Haley believes in the supernatural, and that the only reason it has yet to be proven to exist is because no one has taken a sufficiently scientific approach to it.

Pre Season 3
As a baby, Haley was left at a hospital under safe-haven laws. She was adopted by Patrick Connelly and Fred Holst. At age 14, Haley declared she was going to be an astronaut.

In her freshman year at High School, Haley helped found the Mystery Solvers' Club alongside Bob McGovern, Maurice Bailey, and Kevin "K.C." Cardenas. In the summer prior to her senior year, she and her fellow club members went on a road trip around the Kentucky/Indiana/Ohio tri-state area investigating mysteries. Notably, Haley solved a mystery of a vicious bloodstained deer that turned out to be kids throwing red paint at it.

Maurice Bailey
Haley sees Maurice Bailey as a 'fellow intellectual', approaching the subject of the supernatural in an intelligent manner.

Bob McGovern
Haley gets stressed out at how relaxed Bob McGovern can be about everything, but does think they are nice.

K.C.
Haley thinks K.C.'s problem is that he's a serious introvert. His prickly exterior quickly falls away and he is actually nice once you get to know him.

Martha
Haley works part-time on Martha's horse ranch, and wants her to like her. Haley views everything through the lens of theoretical knowledge, which fails to satisfy Martha who values practical experience most.
