TOUGEN ANKI Episode 15
TOUGEN ANKI Episode 15: The Price of Purity The Teaser: The Blade of Retribution The veil of uneasy truce shatters as the ancient, devastating power of the Momotaro lineage is unleashed not against the monstrous Oni, but against the very foundation of balance.
Episode 15 throws protagonist Shiki Ichinose into a paralyzing dilemma: the ultimate Oni-killing artifact, the Kibitsu-hiko Blade, has been activated by the ruthless Momotaro Purist Faction within the Kibitsu Academy.
Its target? Not just the hidden Oni stronghold, but every single half-blood and human sympathizer.
The air crackles with the energy of inevitable catastrophe.
Who is the true monster when the saviors turn executioners, and how can Shiki, a boy with Oni blood running cold in his veins, stop a weapon designed specifically to eradicate everything he is? A single, desperate choice now determines the fate of two worlds.
The Core Conflict The conflict is immediate and deeply personal: Shiki must physically incapacitate his former ally and current radical rival, Naito Kijima, before Kijima finishes charging the Kibitsu-hiko Blade, which is currently poised to perform a devastating, species-wide purge.
The tension is amplified because the battleground is the sacred (and highly vulnerable) subterranean energy core of the Kibitsu Academy itself a location that, if destroyed, would collapse the academy and expose the entire Momotaro organization to the world.
Shiki is fighting not just for his life, but for the continued secrecy and existence of both sides of the war.

Naito Kijima The Momotaro Purist Leader.
Primary Antagonist.
A zealot consumed by the ancestral hatred of Oni.
He believes the only way to secure lasting peace for humanity is through the absolute, genocidal eradication of the Oni race, using the newly recovered Kibitsu-hiko Blade as the final tool.

Emotional Anchor.
The only Momotaro descendant who refuses to believe the mounting evidence pointing to Shiki's betrayal.

Elder Sakaki The Betrayed Mentor.
Gatekeeper.
The former head of the Academy’s security and Kijima's mentor.
He appears briefly to try and stop Kijima, motivated by a fierce loyalty to the Academy’s traditional, non-genocidal mandate.
His failure sets the stage for Shiki's intervention.
Important Scenes in Sequence The episode opens immediately following Elder Sakaki's failed attempt to seize the Kibitsu-hiko Blade from Naito Kijima in the depths of the Academy’s sealed Energy Vault.
1.
The Vault Lockdown and Sakaki’s Plea The episode begins with Elder Sakaki pinned to the wall by Kijima’s refined Peach Chain technique.
The Kibitsu-hiko Blade a terrifying, ornate sword pulsing with a dense, white-hot energy floats before Kijima, connected to the vault’s massive energy conduits.
Kijima has overridden all safety protocols.
Sakaki coughs blood, his final words echoing: Naito, this power.
it was meant to seal, not to destroy! You are a fool if you think purity can be achieved through total annihilation! Kijima, his face rigid with cold conviction, ignores him, stating: Foolishness is compromise.
I am merely finishing what Momotaro began.
He activates the final charging sequence, initiating a loud, three-minute countdown broadcast throughout the entire hidden academy complex.
2.
Shiki’s Desperate Descent and Satsuki’s Interception Shiki, having just received a panicked, telepathic pulse from Uzumaki, realizes the gravity of Kijima’s action.
The pulse confirmed the blade is locked onto the ancestral Oni settlement grid a network that would eliminate all Oni in a single blast.
He races through the labyrinthine, collapsing service tunnels toward the vault, his own Oni markings (the Horns of Arakawa) only partially materialized to avoid detection by the Momotaro security systems.
He is intercepted by Momozono Satsuki, who stands guard at the final access point.
She is distraught, holding a cracked communicator that shows the Momotaro leadership declaring Shiki a rogue Oni agent.
“Shiki, stop! They know! They know you have Oni blood they think you led Kijima to the Blade!” she screams, tears streaming.
Shiki, unable to explain the complex political trap, merely grips her shoulder, his eyes pleading.
Trust me, Satsuki.
He's not after the Oni.
He's after everything.
If I don't stop him, there won't be a world left for either of us.
He uses a burst of raw Oni strength to bypass her defense without harming her, forcing himself through the blast doors as the countdown hits T-minus 90 seconds.
3.
The Duel of Destined Hate (T-Minus 60 Seconds) Shiki bursts into the vault, confronting Kijima.
Kijima smiles, a look of chilling triumph on his face.
Shiki Ichinose.
I always knew your loyalty was a lie.
It's fitting that the last of your impure line attempts to defend the very corruption I am eliminating.
Kijima unleashes his full power, combining his advanced Peach Chain techniques with the ambient energy drawn by the Kibitsu-hiko Blade.
The battle is brutal and asymmetrical.
Kijima, powered by the Blade's proximity, moves with superhuman speed and precision.
Shiki is forced to rely on raw, uncontrolled Oni power, manifesting a spectral, blood-red gauntlet to deflect the powerful, blinding white-energy attacks.
Shiki's signature move, the Reversed Peach Split, manages to momentarily stun Kijima, but the counter is swift and decisive.
Kijima impales Shiki's spectral armor with a chain, pinning him near the vault wall.
4.
The Revelation of the Blade’s True Purpose (T-Minus 20 Seconds) Pinned and wounded, Shiki screams, demanding to know the final target.
Kijima laughs maniacally, revealing the devastating twist: It's not just the Oni settlements, you fool! The ancient texts state that Oni power cannot be destroyed only sealed.
This Blade doesn't destroy the Oni; it seals all existing Oni energy and redirects it to the Momotaro bloodline, transforming us into true, immortal gods! Your death is just a byproduct, Shiki.
But the world will hail me as the savior who achieved apotheosis.
This revelation horrifies Shiki: Kijima seeks to steal, not destroy.
At that moment, the spectral telepathic projection of Uzumaki flickers into existence behind Shiki.
The balance.
it was not a truce, but a prison! If he absorbs the full Oni power, he becomes the True Peach Demon a god of absolute chaos, bound by neither morality nor balance! 5.
The Impossible Sacrifice and the Catalyst (T-Minus 5 Seconds) Realizing he cannot beat Kijima without the blade's energy being redirected, Shiki makes a split-second decision.
He fully unleashes his Oni transformation the Arakawa Horns erupting fully, his eyes blazing red and focuses his bloodlust not on Kijima, but on the vault's energy conduits.
Ignoring the pain from the Peach Chain impaling him, Shiki channels a massive burst of Anki (Oni energy) into the main conduit.
This is a deliberate, targeted act of overload.
The powerful Oni energy, incompatible with the refined Momotaro power flowing into the Blade, causes a catastrophic feedback loop.
The Blade, which was seconds from completion, begins to shriek and buckle.
Kijima, sensing the impending destruction of his plan, pulls the Peach Chain back, screaming in fury.
You suicidal half-breed! You've ruined the ritual! 6.
The Collapse and the Escape As the countdown hits zero, instead of firing the purifying beam, the Kibitsu-hiko Blade explodes in a localized, non-lethal (but utterly devastating) burst of white and red energy.
The vault structure collapses.
Shiki, barely conscious, finds himself shielded by a shimmering, golden dome Momozono Satsuki's last-second deployment of her family's defensive technique, the Hime Barrier.
She managed to follow him, witnessed his full Oni transformation, and yet still chose to protect him.
Kijima is knocked unconscious by the blast, his body severely burned but stabilized by his Momotaro powers.
Satsuki grabs the unconscious Shiki and Kijima, dragging them both out of the collapsed vault as Momotaro recovery teams begin to swarm the site.
The Dramatic Conclusion and Twist The episode concludes in a quiet, forested clearing hours later.
Satsuki has used a highly restricted teleportation array to escape the Academy with both Shiki and Kijima.
The End: Satsuki stares down at the unconscious Shiki, his Oni markings slowly receding.
She has seen the truth of his identity and Kijima's madness, but her conviction remains unwavering.
She realizes Kijima will soon wake up and expose Shiki, initiating a full-scale war.
The Twist: As Satsuki reaches into her pouch to find medical supplies, her hand brushes against something metallic.
She pulls it out: a small, silver shard of the Kibitsu-hiko Blade.
The shard, no bigger than a fingernail, begins to throb faintly, and Satsuki instinctively clutches it to her chest.
Then, from the shard, a cold, ancient voice that is not Uzumaki's whispers directly into her mind: I am the Blade's voice.
I am the true Momotaro.
