Kallisto Darwin is a college student in the University of Santo Tomas who joined the subversive organization known as the Laniakea. She was provided with a supply of hand grenades.
Her Above and Beyond counterpart is Kaliban Darwin.
At some point in 2018, Kallisto Darwin enrolled in Philippine Science High School's Main Campus.
Kallisto was introduced by Torvaldo to one leader of an organization that would later be called the Laniakea. This intrigued her, and she agreed to join the team, being provided a bag of grenades, one of which she almost blew herself up with.
Later, she is seen recruiting Zeldris and Liesell, and assisting them with a heist on the Math unit.
Kallisto attends the batch's Graduation Ball after she graduates high school. During the ball, she loses her memory due to the cataclysmic result of Sachikayla and Tyriann's falling out.
To be added
Kallisto is adventurous and thrill-seeking, sometimes to the point of recklessness. She is extremely loyal to the Laniakea primarily due to the L.E.N.S.es affecting her mind, though the incident at the Graduation Ball has changed that momentarily.
