Ota Gyūichi served as a scribe chronicling Oda Nobunaga’s exploits during the Sengoku period, crafting embellished accounts that magnified his lord’s achievements and solidified Nobunaga’s fearsome reputation. Following his death, Gyūichi entered a cycle of reincarnations in the modern era, first reborn as a cow on Ota Ranch—a brief existence terminated when his meat was consumed by Nobunaga and other reincarnated warlords. Subsequent lives saw him inhabit forms like a stinkbug, an ant, or raw meat, each ending swiftly in darkly comedic fashion, reinforcing a narrative loop defined by absurd demise.

His historical exaggerations, intended to exalt Nobunaga, inadvertently perpetuated the warlord’s image as a demonic tyrant across later eras. This fixation extended into their past dynamic, with Nobunaga characterizing Gyūichi’s devotion as obsessive and borderline stalker-like. Though loyal, Gyūichi’s distortions of truth complicated their relationship, a tension echoing into their reincarnated existences.

Gyūichi’s modern iterations remain confined to this pattern of fleeting rebirths and humiliating deaths, functioning as a recurring comedic mechanism within the series rather than evolving beyond this cyclical role. His narrative purpose centers on reinforcing thematic contrasts between historical mythmaking and its absurd, unintended legacies.
