Kolulu is another one of the many mamodos that were sent to Earth to determine who would become the next mamodo king. Unlike most mamodos Kolulu did not want to come to Earth to fight, so she was given another personality that was brought out during battle. But the viscous personality would not stay unless the book reader read a spell countless times. Kolulu's book reader was a teenaged girl who she sawll as her big sister.

Her book reader even hand made a doll for her, which she named Tina. Kolulu is the reason Zatch decided he wanted to become a kind king, that way he could make it to were they wouldn't have to fight anymore to see who would become king.
