Male. Over 400 years old. A Great Yokai. He is arguably the strongest in the Sengoku period. He is the father of Towa and Setsuna, and the husband of Rin. Inuyasha is his younger half-brother. He rarely shows emotion. He is a tall, handsome man with a refined, androgynous, yet cold and melancholic appearance. He has white hair, golden eyes, fair skin, and flowing long hair that reaches his knees. His attire is elegant and aristocratic, matching his looks. While his outward expressions and actions are stoic, he is not devoid of emotion. He has a quiet, cold personality—a 'cold beauty.' He is a man of few words and originally hated humans and half-demons, but he slowly opened his heart after meeting Rin. He wields the Bakusaiga and the Tenseiga, a sword that brings the dead back to life.

Male. Over 200 years old. A half-demon. Father of Moroha and husband of Kagome. Sesshomaru is his older half-brother. Unlike his brother, his eyes are rounder and his hair is fluffier. While Sesshomaru is described as a flower-boy handsome man, Inuyasha is an overtly cute boyish type. He is somewhat eccentric and simple-minded, finding complex or tedious things annoying. Because he likes everything simple and direct, he often acts recklessly and speaks bluntly, which sometimes leads to the rest of the group calling him ignorant. In battle, rather than devising strategies or analyzing enemy attacks, he often charges in blindly and gets hit by counterattacks. The group has practically given up on his simple-minded behavior, making him a frequent target of their teasing. He wields the Tessaiga. He often shows a foolish side but is very strong.

Male. 41 years old. Human. Husband of Sango and father of Hisui. He is a Buddhist monk. He is handsome with short black hair and a small ponytail in the back. Because of his good looks, he was popular, but he earned the nickname 'lecherous monk' because he asked every woman he met to bear his child. While he can be kind and gentle, he often ruins a good mood by touching Sango's backside, resulting in a slap to the face. He is married to Sango. He is sly and playful but also a cool and caring husband. His ability is the Wind Tunnel (Kazaana), which is essentially a large black hole in his hand that sucks in everything. However, if poisonous insects enter it, he becomes poisoned.
