Kayla

Kayla Corlett is the main focus of the Intermission sequences of A Quadrilateral Is You!. She is the older of the Corlett sisters (the younger being Katie Corlett), as well as the more introverted of the two. She is an alchemist, able to turn materials like lead into precious metals like gold, which she does often for major profits. The intermission sequences depict the events of her life soon after Katie departs for Anheiba. The first Intermission sequence takes place roughly three days before the start of Act 1. She is introduced on page 182 of the mirror. She first appears in Intermission 1.

Backstory
Very little happened in Kayla's life prior to the events depicted in the Intermission sequences. She mostly kept to her own work, producing and selling not only gold and silver but several miscellaneous items as well, such as acids and potions. Soon after Kayla boarded a ship to Anheiba, she began to reminisce about her childhood with her sister. Near the end of Intermission 1, she is kidnapped by an unknown group of pirates.

Personality
As shown in Intermission 1, Kayla seems to be a rather snobbish egotist who thinks poorly of her younger sister, claiming that she's a dimwitted young girl who decided to journey to Anheiba on impulse for some kind of thrill ride and that she doesn't care what happens to her. However, it's quickly revealed that Kayla does indeed care about her sister and is worried sick about her safety, and that her fake superiority complex is merely her way of trying to block out that worry.

Relationships
Katie - Kayla is Katie's elder sister, though the two don't meet for the entirety of the adventure following Katie's departure to Anheiba. Katie looks up to Kayla as a role model and a guardian, but believes that bringing her along on her journey would needlessly put her in danger. Meanwhile, Kayla appears to look down on her sister, seeing her as an oaf, but she really is concerned about her sister's well-being.

Exceptional Skills
As a secondary character, Kayla is not able to use any sort of battle commands or skills.
