Description
Kanako Yamazaki is a central figure in the narrative, initially appearing as a waitress at the tea house called Hakobune. Her outward appearance is distinctive yet deliberately plain, featuring hair styled in two braids and a face dotted with freckles, which contributes to her initial characterization as someone who is not primarily defined by conventional beauty.

Her background is the key to understanding her personality and actions. Kanako is a ghost, a girl who died during the bombing of Yokohama in 1945 while working as a mobilized student laborer in an aircraft factory. This origin, spanning over sixty years before the story's present, means she has no shadow and does not sweat, subtle markers of her spectral nature. Her early life was marked by poverty and hard labor, an experience that forged a deep-seated resentment towards those she perceived as privileged, such as her eventual friend Yayoi Fushimi and the protagonist Sayoko Arashiyama.

This resentment manifests in a personality that is gruff, violent, and initially hostile. Kanako is a vicious fighter and does not hesitate to use physical force, particularly against any man she believes is harassing or threatening Yayoi. She spurned Yayoi's early attempts at friendship, her pride and spite acting as a shield against someone from a wealthier background. A transformative incident occurred when Yayoi, from the future, saved Kanako's life during the war. This event radically shifted her perspective, softening her hardened edges and igniting an intense, unwavering loyalty towards Yayoi that would define her afterlife.

Kanako's primary motivation is the protection and preservation of Yayoi Fushimi. Their bond, forged in the shared trauma of wartime labor and solidified by a life-saving act, is the anchor of her existence. This devotion drives the central conflict she initiates. As ghosts, both Kanako and Yayoi found their ethereal bodies weakening over the decades. Desperate to avoid oblivion for herself and her closest companion, Kanako resorted to stealing the life energy from Sayoko Arashiyama, a fellow ghost. She attacked Arashi and attempted to kill the living boy Hajime Yasaka and later Hideo Murata to secure this energy supply.

Key relationships in her existence are few but profound. Her bond with Yayoi is the most significant, evolving from resentment to fierce guardianship. Her initial antagonistic relationship with Arashi is rooted in class envy and the pragmatic need for survival. She also forms a crucial connection with the private investigator Hideo Murata. Kanako eventually learns that forming a genuine connection with a living human can restore her energy without causing harm, leading to a symbiotic partnership with Murata, who works as a handyman at the tea house. This relationship allows her to move away from parasitic survival towards a more stable existence.

Throughout the story, Kanako undergoes a notable development. She begins as a hostile, isolated figure driven solely by survival and loyalty to Yayoi. Her arc involves confronting her traumatic past and learning to trust the living. After her initial plan to drain Arashi's power is foiled, she almost disappears herself but is saved by other characters. This crisis forces her to adapt, and she gradually shifts from an antagonist to a reluctant ally, channeling her fierce protectiveness into collaboration with the group. Her evolution shows a capacity to move beyond her rigid class-based grudges and find a new way to exist in the world.

Kanako possesses specific abilities tied to her nature as a ghost. Her most significant power is the ability to travel to any point in the past, but only when she is with her living partner, Hideo Murata. This shared ability is the central mechanic of the series' time-traveling adventures. She is also known for a peculiar and involuntary transformation, more prominent in comedic episodes; when she wears a pair of glasses, particularly those belonging to Hajime, she transforms into a "Beautiful Maid Soldier" or a magical girl. While this is played for humor and is something she deeply fears and tries to avoid, it demonstrates an unstable and unique supernatural reaction to specific stimuli.
