In the anime Shura no Toki: Age of Chaos, Iori is a young boy who serves as an apprentice to the legendary swordsman Musashi Miyamoto. He is depicted as a child with black eyes and black hair that reaches approximately to his ears, sometimes worn in a ponytail. His role in the narrative places him as a witness to the intersection of several key individuals during the early Edo period, including his master Musashi, a young master named Kisshoumaru who is secretly a girl named Shiori, and a seemingly simple but immensely strong young man named Yakumo Mutsu.

Iori's personality is characterized by a spirited and earnest nature, typical of a young samurai in training. He is described as a spunky samurai wannabe who is eager and remarkably perceptive for his age, often noticing details that others might overlook. Despite his enthusiasm, his fighting abilities are limited, and he is not yet a capable warrior, though he does participate in some combat situations. His primary relationship is with Musashi Miyamoto, serving under the famous swordsman and learning from him. Through Musashi, Iori's path crosses with Yakumo and Shiori, placing him in proximity to the central conflicts of the first story arc. His story is woven into the larger tapestry of the series, which focuses on the encounters between the practitioners of the Mutsu Enmei-Ryu unarmed fighting style and the strongest warriors of their respective eras.
