When Megumi was young,she always dream about being a Jōnin herself. Since her family owns a doju inside the house,she always trained there and she always punched walls which makes her hands easily bruised. She din't care whether she loses her strength because the important is she needs to train very hard. One time,Megumi was fighting a Jōnin at the age of 12,she was still a Genin at the time. Her fellow teammates saw her and they want to prevent the fight because they don't want to see Megumi heavily injured,but surprisingly she beats the Jōnin using her Crystal Release techniques.
