Worried about the future of Shonyo, a bereaved child of Ennyo (born in 1516, he was 10 when Jitsunyo died), Jitsunyo left the will to instruct five priests, Renjun, Rengo, Jitsuen (at Honso-ji Temple in Mikawa Province; the 4th son of Jitsunyo and the only male child alive), Renkei (Renko's legitimate child), and Kensei (Renyo's legitimate child) to practice loyalty to Shonyo, to protect the doctrine that had been kept since Sinran, and to coexist with the present political and religious powers.
