Description
Natsuki Subaru, son of Kenichi and Naoko Natsuki, grew up in Japan exhibiting childhood confidence and humor while seeking attention. Living in his athletic father's shadow fostered a severe inferiority complex, convincing him relationships demanded constant performance to prevent abandonment. His resulting eccentric behavior alienated peers, leading to complete withdrawal from school and life as a hikikomori. Consumed by self-loathing and believing his parents better off without him, he distanced himself without farewells.
Mysteriously transported to the Kingdom of Lugunica, he encountered Emilia, a half-elf royal candidate. Her initial kindness became his emotional anchor, fueling his devotion to protect her. He discovered the ability "Return by Death," forcibly rewinding time upon his demise while retaining memories, bestowed by the Witch of Envy, Satella, who claims deep affection. This power imposes severe limitations: attempts to reveal it trigger agonizing spectral hands crushing his heart, potentially killing bystanders. It also emits the "scent of the Witch," attracting hostile mabeasts and repelling those sensitive to it.
Physically, he stands 172 cm with an athletic build maintained through exercise, inheriting his father's black hair and his mother's sanpaku eyes (brown in anime adaptations) with small irises, which some find intimidating. His initial attire was a gray-and-orange tracksuit, later replaced by role-specific clothing like a butler uniform (Arc 2-3) and knight's regalia (post-Arc 4). Notable disguises include cross-dressing as "Natsumi Schwartz" (Arc 7) in a dancer's dress or military outfit, and temporary magical infantilization into a child.
His personality blends playfulness and fierce loyalty with impulsiveness and profound poor self-worth. Arriving in Lugunica, he assumed a "hero" role, using Return by Death to force favorable outcomes for Emilia and allies. This white-knighting prompted reckless decisions, public humiliation, and broken promises. Repeated traumatic deaths and failures—especially witnessing allies like Rem fall into comas or die—intensified his self-hatred. A pivotal shift occurred in Arc 3 when Rem, despite his confession of inadequacy, reaffirmed her faith. Her unconditional support motivated him towards genuine growth over validation through suffering.
He evolved into a strategic thinker valuing collaboration, forging alliances with figures like Otto Suwen and Beatrice, the latter becoming his contracted spirit post-Arc 4. He developed combat techniques including parkour and whip usage, alongside magical abilities like "EMM" (anti-magic fields) and "Invisible Providence" (an invisible arm derived from the Authority of Sloth). His analytical skills allow him to identify opponents' weaknesses, countering Petelgeuse's possession or coordinating the White Whale subjugation. Despite intense hatred for the Witch Cult—especially the Gluttony Archbishop who erased Rem—he learned to temper aggression to avoid endangering others.
Key relationships include Emilia, whom he loves but gradually respects as an equal; Rem, whose coma fuels his determination to restore her memories and name; Beatrice, his spirit partner sharing mana and tactical insight; and Julius Juukulius, an initial rival knight who later earns his respect. His journey involved confronting past regrets through the Sanctuary's trials (Arc 4), revisiting his Japanese life and acknowledging failures. Later arcs show increased resilience, enduring memory loss in the Pleiades Watchtower (Arc 6) and navigating Vollachian political conflicts (Arc 7).
Alternate timelines reveal divergent fates: the "Sloth IF" sees him abandoning Lugunica with Rem to start a family in Kararagi, while the "Pride IF" depicts a manipulative version exploiting Return by Death for control. These scenarios underscore his core trait: an unwavering commitment to protect others, even at great personal cost.
