Heavenkid, Ahya and ToTo are fairies in heaven. One day, they fall into the Evil Dragon Valley accidentally, and Heavenkid is captured by the demon king. To rescue Heavenkind, Ahya and ToTo unfortunately lose their lives, and reincarnate into the human world. To repay Ahya and ToTo’s for saving his life, Heavenkid descends to the world as well. Since ToTo and Ahya make troubles all the time, Heavenkind therefore guides them with Di Zi Gui (Standards for Being a Good Student and Child) to help them become obedient and lovely kids.
