I thought I will just put my translation attempt of Gijiri's bio from Masinowa album booklet.
As I am not even close of having the most fluent or great knowledge in Japanese, please forgive the inaccuracy or awkwardness in my attempted translation.
GIJIRI
Born at Jakotsu, Masinowa’s village for Kagachi. He has a strong hatred towards his birthplace, as it has lost its pride and linked with negative discrimination, and eventually he ends up destroying his birthplace.
In order to find the rightful roots of the lost ancestor, He excavated the ancient ruins nearby the Junaguni island. There he acquired various unknown skills.
After being able to utilize the skill he goes to Wenkamui, a land said to be the origin of Kagachi. There he creates ‘Devil’s Lair’ (Majin’s village), a research facility to pursue the potential of one’s ability. His right eye has the ability to see a person’s ‘real name’, however as it can cause hallucination at the same time, it usually kept hidden.
