Seidou Takizawa, a Rank 2 Ghoul Investigator who graduated second in his Academy class behind Akira Mado, harbored a rivalry fueled by an inferiority complex. His admiration for elite investigators like Koutarou Amon and Kishou Arima drove his ambitions, though office duties restricted his field experience. During the Owl Suppression Operation, he fought Tatara alongside Amon until severe injuries left him presumed dead. Captured by Aogiri Tree, he endured Dr. Akihiro Kanou’s experiments, becoming an artificial one-eyed ghoul via Yoshimura’s kakuhou. Torture amplified his Rc pathways, stripping human weaknesses and fracturing his mind. A final blow came when Kanou secretly fed him his murdered parents’ remains, erasing his last vestiges of humanity. Reborn as “Owl” under Aogiri, Takizawa embraced erratic violence, believing terror could conquer fear. He slaughtered indiscriminately, even former allies, yet flickers of his past lingered—resentment toward the CCG for abandonment, insecurities about mediocrity, and volatile encounters with Akira Mado and Kousuke Houji that exposed shame and unresolved bonds. During a clash with Akira, her invocation of Amon’s name halted his near-fatal assault. Ghoulification altered his physique: white hair, blackened nails and lips, shadowed eyes, and a left-eye kakugan. His wardrobe shifted from Aogiri’s black robes to a trench coat as partial sanity returned. Combat relied on Yoshimura’s ukaku kagune, launching crystalline blades and projectiles. His kakuja evolved from a frenzied, self-destructive state to a controlled owl-masked form, rivaling Amon’s kakuja and defeating Tatara, though overuse hastened mental decay and mortality. Defecting from Aogiri, he allied with Ken Kaneki’s Goat during the Dragon conflict. Post-battle, rumors depicted him roaming as a half-kakuja, hunting rogue ghouls. His trajectory twisted from aspiring protector of humanity into a ghoul accused of consuming his mother—mirroring the evils he once fought. Recurring motifs like biting his left hand (tied to death and emotion) and tarot’s Devil card symbolism highlighted his fractured duality. His fate remained unresolved, with sporadic sightings hinting at survival. Torture, identity erosion, and forced cannibalism left him fractured—a volatile pendulum between vengeful brutality and fragile clarity, embodying the narrative’s themes of trauma and dehumanization.
