Kaname Tanuma, a 15-year-old high school student of slender build and 171 cm height, carries an air of quiet detachment. His short, disheveled black hair and shadowed eyes mirror his initially reserved demeanor, often leaving his expression appearing distant and withdrawn. The only son of a Buddhist monk, he resides in a temple, his childhood marked by frequent relocations due to his father’s duties. Inheriting faint spiritual sensitivity, he perceives spirits as indistinct shadows and senses their proximity, though this ability exacts a toll—frequent illnesses and debilitating headaches when near supernatural entities. Tanuma forms a steadfast bond with Takashi Natsume, one of the rare individuals privy to Natsume’s capacity to see youkai. While anxious about Natsume’s engagements with spirits, he reluctantly accepts his friend’s resolve to aid them, persistently offering support despite his own constraints. His protective instincts flare when figures like Madara or Shuuichi Natori belittle Natsume’s struggles, fueling his quiet resolve to shield his friend. As time progresses, Tanuma’s health stabilizes, with fewer ailments plaguing him—a change he likens to a pin acquiring magnetism through proximity to a magnet, crediting Natsume’s influence. Beyond his spiritual ties, he reveals an aptitude for music, showcased when he plays the piano in Chapter 84 of the manga. Embedded within his name lies symbolic weight: "Kaname," signifying "cornerstone," contrasts with "Tanuma," meaning "swamp field," reflecting the duality of stability and murky depths within his quiet existence.
