Shichiri Yorichika started out as a minor samurai at Hongan Temple, but caught Kennyo's eye and became a temple official and the commander of the Ikkou-ikki forces in Kaga Province.
During Oda Nobunaga's siege of Ishiyama Hongan Temple, he attacked the Oda army repeatedly, earning him the nickname "the Kaga General". As his power and influence increased, so did his arrogance, leading to violent outbursts of anger that sometimes resulted in the executions of his underlings over disputes. Shimozuma Rairen interceded, and in the end Yorichika was driven out of the temple. This resulted in internal strife between the Ikkou sectarians of Echizen and Kaga, providing Nobunaga an opening which he took in August of 1575. Yorichiki fled without putting up a fight.
In the following year he accused the master of the Ikkou castle of Mattou of rebellion and attacked, but was defeated and killed.
