Huci's Brother (アシリパのフチの末弟, Ashiripa no Fuchi no Battei) is the youngest brother of Huci (Asirpa's Grandmother), and the youngest of six siblings.
Huci's Brother wears the customary Ainu clothing over a dark robe that he keeps in place with a sash. His black and white hair is parted sideways and over his ears adorned with big hoop rings. He has a white medium length beard, and like his siblings, his eyes appear to be closed.
Huci's Brother can only speak the Ainu language. He is a hospitable person, as he was willing to let strangers stay in his village.
When his great-niece Asirpa came to visit him along with Saichi Sugimoto, Yoshitake Shiraishi, and Kiroranke, he allowed them all to stay at his village. He commented that his village has also received another visitor, and introduced them all to Inkarmat. He silently watches the others having a conversation as he is unable to speak Japanese. Inside his home, he confirms Kiroranke's statement that Inkarmat's predictions are accurate and that the other villagers have been giving her gifts.
