A boy who came a million years ago
Amasso returned the boy's fossil to a human form with magical power and sent him to the museum where the mammoth fossils he once had a good friend were enshrined. The boy shoots a fire arrow, and the mammoth fossil becomes a Haniwa phantom mammo and starts a rampage. People who panic and run away. The air that confronts is hesitant to fight against a boy who is not originally an enemy.
