Description
Kagome Higurashi's grandfather, often referred to simply as Grandpa, is the elderly patriarch of the Higurashi family and the custodian of the centuries-old Higurashi Shrine in modern-day Tokyo. He is identifiable by his traditional Shinto priest attire, which reflects his lifelong role as the shrine's caretaker. As the head of the household following the tragic death of his son, Kagome's father, he lives with his daughter-in-law Mama Higurashi, his granddaughter Kagome, and his grandson Sota.

Grandpa is a man of deep, unwavering belief in the spiritual and historical significance of his family's shrine, including its sacred tree and the Bone-Eater's Well. He has a passionate, though often long-winded, tendency to lecture on the history of seemingly mundane objects and family traditions, frequently attempting to educate Kagome on matters he finds fascinating, such as the supposed origins of pickles, much to her visible dismay. Despite his serious demeanor regarding these matters, he is a deeply caring and supportive grandfather who dotes on Kagome. His care manifests in his primary role within the modern-day narrative: inventing a series of increasingly absurd and mysterious illnesses to excuse Kagome's prolonged absences from school, which often cause her friends great concern.

His motivations are rooted in protecting his family's well-being and maintaining the integrity of the Higurashi Shrine. He is also motivated by a desire to pass on his knowledge and ensure the shrine's legacy continues, harboring hopes that his grandson Sota will one day take over its management. In the story, his role is largely confined to the modern era, providing a link between Kagome's life as a middle school student and her adventures in the feudal era. He is a source of comedic relief, particularly in his interactions with Inuyasha, whom he views as reckless and troublesome. His attempts to seal the Bone-Eater's Well with powerful ofuda, or written oracles, are famously and immediately thwarted when Inuyasha tears through them with ease, dismissing them as mere scraps of paper. On another occasion, he briefly hired Inuyasha to work at the shrine, only to fire him for knocking over shelves.

Beyond his comedic function, Grandpa's knowledge proves subtly significant. Throughout the series, he provides historical context and stories related to the artifacts he sells and cares for, such as imitation Shikon Jewel keychains. One of his stories, concerning the beads of subjugation and the concept of a marriage bead, provides a critical hint that ultimately guides Kagome toward making the right choice at the climax of the final battle with Naraku, a detail Kagome had previously dismissed. This reveals that his rambling lectures, while often ignored, are grounded in genuine lore that becomes pivotal to the resolution of the main conflict.

In terms of abilities, Grandpa is a practicing Shinto priest who manages the shrine's grounds, performs religious ceremonies, and handles artifacts brought to him for blessing, cleansing, or sealing. He sells various religious trinkets and demonic memorabilia to help pay the shrine's bills. While his spiritual powers are demonstrated to be effective against certain threats, as seen when he protects himself from an ancient Noh mask using an amulet, his abilities are consistently shown to be far outclassed by the level of demonic power Inuyasha and his allies face. His ofuda, for instance, have little effect on powerful demons or half-demons, leading to some ambiguity about the true extent of his spiritual strength.

Grandpa's relationship with Kagome is one of devoted, if sometimes comically misguided, affection. His relationship with Inuyasha is strained, marked by mutual annoyance. He exhibits little to no character development over the course of The Final Act, remaining a consistent source of humor and familial support from the modern world. His persistence and devotion to his family are constants, and he survives well into the future, appearing in the sequel series Yashahime as the great-grandfather of Moroha, still living at and managing the Higurashi Shrine.
