A dog half-demon. He is a yokai who is half-human and half-dog. His plan is to find the shards of the shattered Shikon Jewel, complete the jewel, and take it for himself to become a full-fledged demon! Inuyasha is 200 years old (though he looks 16) and fights with a sword called Tessaiga. He is a half-demon with a surprisingly mischievous side. He is incredibly fast and has a high jumping ability. He enjoys climbing up and lying or sitting on thick tree branches.

Kagome is an ordinary second-year middle school student who can travel between the Sengoku era, where Inuyasha lives, and the modern era through a well. After accidentally shattering the Shikon Jewel, she is currently traveling with Inuyasha to collect the shards. She is the daughter of a family that has managed the ancient Higurashi Shrine in Tokyo for generations; like a typical modern middle schooler, she helps with shrine work but isn't particularly interested in it. She was a bright, ordinary model student who cherished her family and friends and focused hard on her studies.

16 years old. Female. A demon slayer. She always travels with her long-time friend and family member, the cat demon Kirara, and rides a transformed, enlarged Kirara during long-distance travel or combat. Having spent a long time active on the battlefield as a slayer, she usually appears tough and calm, but she is actually quite emotional and sensitive. Her joys and sorrows show clearly on her face. She is the most affectionate and soft-hearted member of Inuyasha's group. She isn't the type to get angry easily, but when she truly loses her temper, she becomes terrifying.

18 years old. Male. A young monk who has undergone demon-slaying training. His most prominent feature is the Wind Tunnel, which sucks in everything like a black hole; besides that, he uses spiritual power to exorcise demons with charms or his staff.

7 years old. Male. His hands and face are human-like, but his tail and feet are fox-like, making one wonder about his physical structure. Meanwhile, he mainly serves as the group's straight man; his daily routine involves teasing and provoking Inuyasha with his cheeky personality, and he says whatever is on his mind even if the opponent is a powerful Great Demon. He does not use honorifics like 'big brother' or 'big sister'.
