Ultraman Company

A mysterious ancient statue called Moyamoya is stolen from a department-store event while Ultraman Company is responsible for security. Company president Seven promises the owner, Boss Gyan, that the statue will be recovered within four days.

The investigation quickly turns strange when the team learns that Gyan himself arranged the theft and that the stolen statue was only a fake. The real Moyamoya lies on Peropero Island with Gyan's brother, Dr. Yango, sending the Ultra team toward the island and the secret hidden behind the ancient relic.
