Description
Created by the mysterious Beholder, Fushi began as an immortal entity arriving on Earth as a featureless white orb. This inert form awakened through environmental interaction, first mimicking a rock, then moss, and finally a dying white wolf. Mistaken for a deceased pet named Joaan by an isolated boy, the entity witnessed the child's death from an untreated leg wound. Honoring the boy's final wish to be remembered, Fushi permanently adopted his appearance—a white-haired youth with golden eyes.

March, a girl destined for ritual sacrifice, named him "Fushi" (immortality). Her brief companionship ignited his linguistic and emotional growth. Bonds with others—like Pioran, who taught him language and caretaking, and Gugu, a disfigured boy exemplifying heroism—deepened his understanding of human connections. Each significant death, including March, Parona, Gugu, and Pioran, expanded his transformative repertoire and emotional complexity.

Fushi’s immortality enables rapid regeneration, accelerating from days to seconds after repeated deaths. He shapeshifts into deceased beings whose deaths left strong impressions, retaining their memories and abilities without fatal wounds. Early forms included the wolf, the nameless boy, March, and Gugu; later additions encompassed allies like Tonari and Bon. His eyes remain golden across all forms. Contact allows replication of inanimate objects, evolving from simple rocks to complex structures like buildings after intense stimuli. He eventually manipulates territory through planet-spanning vine-like roots for environmental sensing and control.

During the Renril arc, Fushi gained resurrection: recreating bodies to restore lives if their lingering souls ("Fye") remained, requiring prior observation of them alive. Spiritual energy manipulation lets him interact with souls, such as communing with deceased companions in Bon’s form. Resurrection prevents him from shapeshifting into that person unless they die again.

Fushi’s personality evolved from instinctual mimicry—copying actions without understanding, like inappropriate laughter—to profound empathy. Witnessing human suffering, especially bonded companions' deaths, forged a deep aversion to pain and conflict. He avoids killing and initially hesitated against evolved Nokkers expressing pain and coexistence desires. Despite compassion, human complexities challenge him, often causing bluntness that strains relationships. Threats to companions trigger protective rage, though centuries taught him greater emotional regulation.

After centuries of post-Renril isolation suppressing Nokkers globally, Fushi awoke in the modern era to confront microscopic Nokkers parasitizing humans—including Mizuha, the latest reincarnation of his obsessive adversary Hayase. Conflicts forced moral dilemmas about coexistence versus eradication. Refusing omnipotence from the Beholder (now embodied as Satoru), he dismantled Hayase’s Nokker network while permitting others to persist. His final acts liberated cybernetic beings from forced longevity, created artificial bodies for allies, and allowed resurrected friends to depart after 300 years together. He remains Earth’s eternal guardian.
