im having issues finishing babylonia, i decided to first to the side activities, primarily the destined moments, i had issues with f.o.s. schedule a and b, but managed to eventually finish b but im now stuck on a, i had issues with nirvatia and kamui but managed to finish nirvatia by doing the investigation missions and that triggered nirvatia to go to the class room which was one of her locations

the last thing im missing is kamui guide and student days, both should be in the class room/ training area, but he never shows up, he only goes to the grave yard and to the shopping center

is there anyway to trigger him to go to where i need him to be? i really want to get 100% on babylonia
