Mantis Civil War

Yoritomo Kitao and Yoritomo Kumiko both claimants to the title of Mantis Clan Champion privately seek the recognition of the Emperor Toturi III. The Emperor agrees to support whoever can bring an end to th eone who can end the conflict.

This promts Kitao to launch an attack on Kumiko at her home in Kyuden Gotei. The fighting is fierce, but Kumiko soon gets the upperhand and defeats Kitao in personal combat.

The Mantis Nightmare, Settozai, the Onisu of Larceny is revealed to have exasberated the situation through it's vessel, the shugenja Ishada. Kumiko kills the Onisu, cleansing herself of her inborn Taint by using a technique she learnt from the secret ronin brotherhood, The Unbroken.

Soon thereafter Kumiko, The Daughter of Storms, is recognized as the Mantis Clan Champion. Kumiko also spares Kitao's life unwilling to see more bloodshed within her clan.
