During the rebellion of the North and South court of Japan, these two regions were closely related fo Kikuchi clan, a key armed force in the Seiseifu(征西府), Kyushu’s Southern Dynasties. Kikuchi clan was trying to control the local families, as the member of the southern side through the religious activities of Daichi, the zen monk. Such Daichi’s leadership was due to his locality, religiosity, and political status. After Daichi’s death, it was the boy who was called Azibaldo by Goryeo soldiers who replaced his role. The fact that his family was a nobleman aristocrat, excellent martial arts, and command ability can be pointed out as the origin of Agibaldo’s leadership. In this paper, it is estimated that this Azibaldo is Ikuranomiya, which is identified only in Japanese literature sources, and tried to reveal the substances. As a result, Ikuranomiya was born in 1365 between Prince Kanyeoshi and Takemitsu Kikuchi’s daughter, and his birth is thought to have been closely related to the independence of the Seiseifu(征西府) from the Yosino court(吉野朝廷). Even if Ikuranomiya (Ajibaldo) is the same person, no special contradiction is found. Rather, in this regard, the birth period of Ikuranomiya, which has not been revealed so far, and it is possible to interpret the movement of the Seiseifu(征西府) to self-reliance complementarily and reasonably with the results of previous studies.
