History
Forty-one years ago, the Mountain God's piglet was captured by a trio of men and taken to the Flower Capital by Kin'emon, prompting its parent to come to its rescue. The piglet began calling for its parent, and when Kin'emon told it to quiet down, Oden arrived to take it from him. One of the piglet's original kidnappers found Kin'emon and warned him that it ate his friends and Tsuru (Wano), causing Kin'emon to drop the piglet and run to fight the Mountain God. After Kin'emon was defeated, Oden held the piglet up to attract the Mountain God's attention and used the opportunity to slice it in half, defeating it.

Several years later when Oden was about to visit the capital, Koyama was asked to get into a crate while its parent waited.
