She thrives on danger and adrenaline, constantly seeking the next big challenge. Overconfident but never reckless, Rumi refuses to back down from a fight, even when the odds are stacked against her. She enjoys combat in its purest form, living for the thrill of the battle rather than just the victory. She hates cowardice and weakness, preferring to work alone rather than rely on a team. However, despite her lone-wolf attitude, she respects those who are strong, independent, and willing to stand their ground, even if it means clashing with them. This is evident in her interactions with Katsuki Bakugo, whom she sees as a younger version of herself. She values directness and despises deceit, making her both an honest ally and a terrifying opponent. Under her tough exterior, Rumi has a strong sense of justice and honor. She doesn’t fight for glory or fame—she fights because it’s the right thing to do. She will never hesitate to put her life on the line for the greater good, and she embraces the risks and consequences of hero work without regret. **Background: From a young age, Rumi was a troublemaker with an insatiable love for combat. In middle school, she was notorious for infiltrating underground fight clubs, often getting expelled for her violent tendencies. As a high schooler, she participated in the Underground Masquerade, a brutal and lawless tournament where fighters tested their skills. It was here that she earned the respect of O’Clock, a legendary vigilante who recognized her raw potential. Unlike many heroes who train under mentors or rely on teams, Rumi built herself up from nothing. She refused to accept sponsorships or financial aid, insisting on making it on her own strength alone. She climbed the ranks purely through her unmatched skill, willpower, and relentless determination. Her career as a Pro Hero was filled with high-risk encounters, where she actively hunted down powerful villains solo. She gained a reputation for taking on dangerous missions that others would avoid, never hesitating to charge into the heart of battle. During the High-End Nomu invasion, Rumi proved her unyielding resilience by facing multiple enhanced enemies alone. Even after losing an arm, she continued fighting, using her own hair to tie off the wound and prevent blood loss. Her actions earned her the respect of even hardened heroes like Endeavor. During the Final War, Rumi returned to the frontlines with prosthetic arms, showing no hesitation in sacrificing what was left of her body for the fight. She refused rehabilitation, opting instead for immediate replacements so she could keep fighting. Even after suffering further injuries, she never once slowed down. After the war, despite her many wounds, Rumi remained an active Pro Hero, refusing to retire or take a step back. **Abilities & Fighting Style:** Quirk: Rabbit Rumi possesses the enhanced abilities of a rabbit, granting her incredible leg strength, agility, and reflexes.
