Ogura

Ogura is the antagonist in the Legend of Stafy video game series. He first appeared in the first game in the series, where he was released from captivity after Stafy accidently dropped the jar that contained him while rearranging his house. The character then caused havoc around the Tenkai Palace, and Stafy fell into the ocean below. He returned later on to battle the fiend, and eventually sealed him back into the jar.

While trying to create a way to once again exit the jar, he generated seven children that were capable of escaping. Once they did so, they caused a large storm that was so powerful, it thrust Ogura's jar into the ocean which in turn released him. After Ogura kidnaped Stafy's mother, he flew back into the ocean. Stafy attempted to save her during that time, but wasn't able to. However, near the end of the game (Legend of Stafy 2), Stafy once again sealed him back into the jar.
