Tsujido Nobu is the youngest son of a declining family of conjurers. He has seen too much of the wretchedness of this pedantic ancient family. His mother, who was "just a commoner woman," brought him to see the current world.
He learned what dignity and equality are.
However, in order to continue the family and revive the family, his father sent him to the Gojo family, one of the three imperial families, to work as a servant for Rokugan.
Fortunately, that person can't stand these pedantic old guys.
Purpose: Break the pedantic system
