Gouki (Akuma) is drawn into a brutal duel with his master Goutetsu. Though the two are evenly matched, Gouki gains the upper hand and ends Goutetsu’s life using the feared Raging Demon technique, leaving the dojo in silence and Gouki’s power visibly warped. When Gouken arrives, he discovers Goutetsu’s mangled body and Gouki, whose appearance betrays a harsher, more inhuman edge. Gouken’s stern words cut through the moment, accusing Gouki of choosing a dark path and doubting whether redemption is still possible. Gouki takes his master’s beaded necklace as a farewell token and disappears into the shadows. Sayaka falls to her knees, vomiting, a stark sign of her pregnancy and the deep, undeniable link she shares with Gouki.
In the present, Ryu returns to his master’s old dojo and is abruptly confronted by a spectral sight of Gouki, who hurls a challenge in the air and vanishes. Recovering, Ryu meets an old man who testifies to witnessing something truly monstrous. The old man invites Ryu into his home, where Ryu meets his granddaughter Fuka and begins to sense an opportunity for training. Sakura Kasuga soon appears and spars with Ryu, a heated exchange that pushes him toward accepting Gouki’s challenge. The journey intensifies as Ryu seeks Gouki, and their duel commences with elemental ferocity.
During the confrontation, Ken Ken crosses paths with the old man and is swiftly defeated, a moment that underscores the old man’s mysterious power. The elder explains the nature of the Satsui no Hadou—a dark, life-fueling force that dwells within certain fighters. If wielded, it grows stronger, eventually consuming its host, a truth so ancient that even warlords once knew of it.
As the fight rages, Ryu temporarily succumbs to the Satsui no Hadou, his resolve bending under its weight. He quickly recognizes that surrendering to that power is not the path toward true greatness and strips it away. Gouki taunts him, insisting that the route to true mastery lies in unleashing one’s full potential, even if it risks damnation. With Ryu momentarily disarmed, Gouki presses the attack using the Metsu Hadouken, and although Ryu survives, the encounter leaves Gouki to go his own way, muttering a curse at Gouken and vowing that their fates will cross again in time.
A poignant image surfaces as Gouki glimpses an apparition of Sayaka tending to his wounds in a past that seems both distant and intimate, before the scene returns to the present. Gouki’s appearance softens somewhat, hinting that he has regained a measure of his humanity in the intervening years.
Back with the old man, the narrative circles to a confession: Gouken had entrusted him with safeguarding a young child and steering them away from Gouki’s dark path after Sayaka’s death during childbirth. The old man laments his own aging and the weight of failing to stop the cycle, while Fuka is shown praying in tears. Ryu takes one last look at her, a silent acknowledgment of the burden he carries, and then sets out once more on his travels, carrying the lessons learned and the weight of the road ahead.
