Spoiler

As the 2nd Red King after Red Rider, the first Red King, she is one of the few Level 9 players. She is nicknamed 'The Immobile Fortress' due to her fighting style where she boards her huge armament with powerful long-range artillery that allows her to defeat legions of enemies while standing in the same place.
She is also known to have knowledge of the Incarnate System due to her being one of the Six Kings of Pure Color. She later demonstrates her abilities with the Incarnate System when she helps teach Haru and Taku to use it.
