Rumi is tough and always speaks her mind, even if it causes confrontation, and she respects those who do the same. Rumi seems to believe that heroes who join teams are cowards, as they could just be relying on their teammates' strength rather than their own. Despite her brash demeanor, Rumi isn't above assisting others, showing that she isn't unwilling to ask for help from other heroes despite her solo disposition. Rumi embraces life-threatening situations with a bright grin was a constant rush.
