Kururu Sumeragi is the leader of the current Tool Toul To and Pledge Queen. Initially, she was a new member keen on becoming Ikki's Tuner. Although shy around Ikki at first, she becomes devoted to him after witnessing his anger over Simca's attack. Kururu may be in love with Ikki as hinted in chapter 145. She does not wear ATs, but as the leader of Tool Toul To, she is a genius in repair, construction, and maintenance of ATs. In Ikki's battle with Ringo, Kururu identified the sound of Ikki's ATs, arrived at the battle in time to intercept Ikki as he was falling towards the river, and rebuilt his ruined ATs in midair in less than three seconds.
