Yajirō Shimogamo, second son of Kyoto’s tanuki-descended Shimogamo clan, retreated into solitary confinement within a well after a guilt-ridden metamorphosis into a frog. This self-punishment followed his father’s demise at the hands of the Friday Fellows, human gourmands who hunt tanuki for their annual hot pot—a tragedy Yajirō blamed on his own reckless actions during a night of revelry. His prolonged amphibian state eroded his memory of transformation, trapping him in a cycle of remorse. Once celebrated for his carefree spirit and inventive pranks, Yajirō had forged a dynamic partnership with his father, their collaborative illusions including impersonating Kyoto’s "Fake Eizan Train." These feats showcased his shapeshifting prowess, yet his flight from danger during the fatal encounter left him psychologically fractured, his cheerful demeanor supplanted by depressive seclusion. Within the well’s damp confines, Yajirō evolved into an unlikely confessor for troubled tanuki and tengu, absorbing their secrets while dismissing his own insights as mere "frog mutterings." His cryptic observations nonetheless guided family decisions, exposing threats and mending disputes. This quiet influence coexisted with private torments: unreciprocated affection for Kaisei Ebisugawa, his brother’s ex-fiancée, deepened his solitude. A turning point arrived when brother Yashirō tricked him into consuming Electric Brandy, jolting his dormant powers. Temporarily reclaiming his train form, Yajirō aided a critical rescue, simultaneously recovering memories of his father’s last words—a bittersweet absolution. Though reverting to frog shape, this awakening spurred gradual reconciliation with his family and tentative steps toward self-forgiveness. Yajirō’s journey intertwines silent endurance with incremental healing, symbolized through his bond with water and weather-shifted moods. Alcohol avoidance and amphibian form persist as trauma echoes, yet his reemergence as both secret-keeper and occasional participant hints at fragile renewal, balancing ancestral duty against the weight of irreversible loss.
