Personailty
Roji is optimistic and always tries to see the good in people. He always tries to help Muhyo as much as he can. He constantly tries to make up for his weak Magic Law abilities by studying. He is skilled in making disguises, which he calls "Super Fab Tech". These include a dresser that he hides inside and pots that he and Muhyo use as disguises. Like Muhyo, he also enjoys reading Jabin.
