OVA
Description
Tachibana Yoshiaki, historically known as Naoe Nobutsuna, serves as a Buddhist monk of the Tachibana family at Utsunomiya’s Kougenji temple. Now 28, he appears eleven years older than Takaya Ohgi, maintaining a reserved presence accentuated by black mourning attire that reflects his grief for the departed.

A "possessor" reborn through centuries, Naoe carries memories of his past life as a vassal bound to protect Kagetora Uesugi—Takaya’s reincarnated identity. This oath, forged 400 years ago under Kenshin Uesugi’s command, began with mutual hostility between Naoe and Kagetora, later warping into Naoe’s obsessive, envious love. His resentment of Kagetora’s status and power culminated three decades before the main narrative in an act of jealousy-driven violence: the assault of Kagetora’s fiancée Minako. The trauma fractured Takaya’s memories of his past life, a guilt Naoe perpetually bears.

Despite inner turmoil, Naoe’s loyalty to Kagetora remains absolute. He wields energy-based magic and spiritual perception against Feudal Underworld threats, operating with calculated secrecy. His dynamic with Takaya veers between fierce guardianship and psychological strife, fueled by guilt and a need for emotional control. Their tense reunion in the OVA *Rebirs of the River Edge* exposes unresolved sexual and psychological friction, mirroring Naoe’s unrequited longing and self-loathing.

A turning point emerges when irreversible damage to Naoe’s soul bars him from possessing new hosts. This fragility provokes Takaya’s fiercely protective instincts, sparking rage when Naoe faces peril. Naoe’s eventual sacrifice to shield Takaya triggers catastrophic emotional fallout: Takaya spirals into temporary madness before numbing his emotions to confront enemies.

Naoe’s journey navigates redemption, self-destructive devotion, and immortality’s psychological scars. His bond with Takaya/Kagetora shifts from adversarial obligation to an entwined reliance, forged through centuries of shared history, trauma, and the echoes of duty that bind them.
