Mini is a 7-year-old mixed-race boy with blue eyes, light skin, and black hair. He has high intelligence, agility and sophistication. However, the boy's singularity is that he is only 1 cm in size, which caused his parents to disown him. Currently, he is wandering around looking for a new place to live, and he has to be extremely careful to avoid being stepped on by people and being discovered by small animals because of his height of only 1 cm.
