Within this organization, she is considered an elite, having achieved the top grades in the Uniformer training program and is referred to by a key figure named Jinki Mukae as the "chosen child of the Uniformers."

However, as the Uniformers' influence grows and they dominate the Vanguard scene with their UNI app, Halona acts as a recruiter, visiting characters like Megumi Ookura to invite them to join the organization. Her central conflict comes to a head during a decisive match at the foot of Hakusan, where she faces Urara. In this battle, her fighting spirit is ablaze as she aims to defeat her former friend to validate the Uniformers' path, while Urara seeks to win in the hope of rekindling their friendship. This match serves as a key point of development for her character, showing that her determination is fueled not just by ideology but also by a personal emotional struggle against someone she once connected with. Her notable ability is her exceptional strength in the card game, being hailed as the strongest fighter produced by the Uniformers plan, a reputation she actively seeks to defend and prove on the battlefield.
