The story takes place in Dragon Country. Nonoko, the heroine, is a newly appointed dentist who protects the dragon, the guardian of the country, from tooth cavity bacteria. One day, amid increasingly fierce battles against the neighboring country, she finds on the dragons tooth an unconscious boy soldier from the enemy country. His name is Bell, and he has been resurrected from within the tooth by the dragon, a supernatural phenomenon that legend says occurs before a major disaster. (Source: Crunchy Roll)
