Ai Tutu is a friendly girl with a flirty and mischievous attitude. She is very confident, often putting herself or Mu Nujiao in uncomfortable positions due to her quick actions. She is the younger sister of Ai Jiangtu, a young prominent military mage. Ai Tutu is good friends with Mu Nujiao. She meets Mo Fan when browsing for a new apartment. She convinces Mu Nujiao to live together with Mo Fan in the apartment. Ai Tutu impersonates Mo Fan at a high risk team competition as she wants to experience the adoration Mo Fan naturally gets. She tarnishes Mo Fan's name due to inability and expects Mo Fan to blow up in anger, however he is most calm about the whole situation. He later defends Ai Tutu as the teammates she participated with as they yelled and insulted her harshly. During the Kraken Invasion she was with Mu Nujiao when Mo Fan came with Azure Dragon and when Mu Nujiao recognized him, she teased her saying it's not the time to be thinking about him.
