Kid (キッズ Kizzu) is a Monster species of the Fire genus. Though Kid itself is not encountered in the Monster Tower, it is the infant form of Dragon; a familiar Kid will evolve into Dragon upon reaching level 20.
Kid is labeled as Monster #03
The word "KID" in the Monsbaiya Region means an infant dragon.
Compared to a dragon, a Kid's magical power is weaker.
Although it can be tamed by the person who hatched its egg, it is still difficult to raise one since it has a severe temper and it only eats metals.
