Raidō Fujimoto, a 54-year-old professional shogi player from Kagoshima Prefecture, first garners attention as the five-term Dragon King, reigning for eight years. His brusque, unapologetic manner clashes with unexpected softness toward proteges like Rei Kiriyama, marked by awkward displays of affection. Though mentally tenacious and sharp-tongued, he harbors tactical vulnerabilities—susceptibility to flattery and rare but glaring in-game miscalculations termed "incredible blunders," which erode his strategic dominance.

Career declines punctuate his trajectory: losing the Dragon King title to Dobashi, followed by a decisive three-match defeat against Tsuchihashi. A pivotal clash with Rei exposes his hubris, as an overconfident oversight forces him to stall their game until Rei acquiesces to a personal vow involving the Kawamoto sisters, intertwining stubbornness with intrusive curiosity.

Married with two daughters, his extramarital indiscretions surface post-title losses, met only with familial censure. Contradictions define his personal conduct—gruff yet intermittently nurturing, offering the Kawamoto sisters guidance on regional customs like sand steam baths and thoughtful gift selections.

Peer interactions further unveil his layered persona. While commentating a critical match between Shimada and Sōya, he misses a key strategy spotted by Rei, spotlighting the divide between his seasoned analysis and Rei’s instinctive brilliance. Such moments chart his transition from shogi authority to a veteran navigating the ascent of new talent.

His arc orbits unresolved dualities: ambition clashing with self-sabotage, stern mentorship juxtaposed with petty obstinacy. Though humbled by defeats, he remains an enduring, complex figure—neither fully diminished nor reformed, eternally balancing abrasiveness with flickers of benevolence.
