Gren

グレン

Gren is frequently regarded as Iria's older brother and a fully qualified hunter. However, in episode 5, Fujikuro hints that Gren may not actually be Iria's brother, but rather her onii-san (a Japanese term referring to both older brothers and close older male figures). He instructed Iria in much of her hunting knowledge and acts as a mentor during her apprenticeship. He wears a blue cloak and hair beads similar to Iria's, along with an unusual pendant that Kei later discovers.
