For example, she saved Julie and Billy from falling. She thinks she is the best brawler ever but is usually brushed off by others and they often drastically underestimate her abilities.
She first battled alongside her brothers Akira and Shuji, planning their strategies and losing, She helped Billy and Julie fight Tricloid. After defeating her, she becomes very nosy in Billy and Julie's relationship.
