Sōsuke Mitsuba, a Kamome Academy student, transitions from a living individual to a supernatural entity following a fatal car accident. Resurrected by Tsukasa Yugi through fragments of his original soul, he emerges as an artificial ghost stripped of human memories, severed from his former identity. This fractured existence fuels an internal clash between his yearning to carve a distinct self and the lingering echoes of his predecessor’s life. Brash and sarcastic, Mitsuba masks vulnerability with boasts about his appearance and sharp-tongued jabs. Moments of solitude or confrontation with his existential void expose his fragility. His middle school persona—gentler, crafted to evade bullying—reverts to abrasive defenses as a ghost, concealing loneliness and insecurity. A fixation on scenic photography replaces his prior talent for capturing people, a deliberate rejection of “easy” subjects that mirrors his pursuit of validation beyond superficial success. Relationships intertwine complexity and contradiction. Kou Minamoto initially imposes the original Sousuke’s identity onto him, intensifying Mitsuba’s crisis. As Kou recognizes his uniqueness, their bond deepens, with Mitsuba acutely attuning to Kou’s emotions, prioritizing his safety even amid self-destructive urges—though he veils concern behind deflection. With Nene Yashiro, fleeting camaraderie emerges, such as endangering himself to shield her, yet he withdraws, haunted by self-doubt or her ignorance of his artificiality. Mitsuba’s journey orbits a desperate search for belonging. Early efforts to inherit Sousuke’s memories and ties crumble, epitomized by adopting the photography club dream while avoiding the camera, a metaphor for his severed identity. Gradual acceptance of his supernatural state shifts his focus toward Kou, observed through his own lens rather than Sousuke’s shadow—a tentative step toward selfhood, yet marred by the impermanence of his connections and the unbridgeable gap from humanity. Physically, he sports light blond hair and a slender frame, often clad in his school uniform. Preferences include flan, autumn’s crispness, spring’s bloom, baking, and music. He recoils from Tsukasa, darkness, and displays of weakness, mirroring his resistance to vulnerability. Mitsuba’s narrative weaves identity and existential yearning, vacillating between craving human recognition and begrudgingly navigating his spectral reality. Ephemeral bonds punctuate his tragedy, a transient existence grasping for permanence in a world that slips through his fingers.
