Anego starts as both classmate and rival to the protagonist, commanding a girl gang that enforces school dominance through intimidation and disruptive actions. Her rugged look contrasts with conventional femininity, defined by habitual smoking and rejection of girlish mannerisms. Their antagonism gradually shifts to reluctant friendship alongside classmate Tetsuko, though Anego consistently doubts the protagonist’s hidden motives.

Her complexity surfaces during a pivotal amusement park date with a school medic, revealing tsundere traits. When external magical interference triggers dangerous ride malfunctions, she displays decisive leadership by taking control of a runaway vehicle to prevent disaster. Despite this heroism, her date reacts with fear and rejection, ending their potential romance and leaving her visibly heartbroken. This reinforces her return to a tough exterior while exposing underlying vulnerability and capacity for deep emotional investment.

She persists as a wary ally within the group, participating in school activities with the protagonist and Tetsuko while remaining skeptical of the protagonist’s manipulations. Her development centers on navigating this uneasy alliance—balancing inherent toughness with protectiveness and emotional wounds from societal rejection of her assertiveness.
