Kidoumaru

Kidoumaru is a monstrous being classified by the Demon Defense Force under the codename “One-Horn”.

He is notorious for his role in a major disaster incident and his complicated, hostile ties to Kyouka Uzen and Yuuki Wakura.

He was originally a feral, rampaging monster, but was later forced into servitude under Aoba Wakura.

Despite this, he eventually breaks free and becomes a central threat during one of the story’s key battles.

Kidoumaru has a large single horn protruding from his head, which is his most recognizable feature.

His overall appearance is described as ugly and brutal, emphasizing his nature as a fearsome ogre.

He is portrayed as physically imposing and terrifying on the battlefield.

This design reinforces his role as both a catastrophic force and a hated enemy.

Within the Demon Defense Force, Kidoumaru is given the operational codename “One-Horn”.

This code refers directly to his singular horn and is used as a practical identifier in combat reports and missions.

The name “Kidoumaru” is the personal name given to him by Aoba Wakura.

This name reflects Aoba’s control over him during the period when Kidoumaru was enslaved as her subordinate.

Kidoumaru was responsible for a major demon-city disaster known as the “Moon Mountain Oizawa Incident.”

During this incident, he unleashed destruction on a massive scale.

As a result of this event, Kyouka Uzen’s hometown was completely annihilated.

Because of this, Kidoumaru became Kyouka’s most hated nemesis and a deeply personal target of revenge.

For Kyouka Uzen, Kidoumaru is not just another enemy, but the direct perpetrator of her greatest trauma.

The destruction of her hometown and people forged a personal vendetta against him.

When they finally face each other, their conflict carries heavy emotional weight.

Their battle is framed as Kyouka confronting the embodiment of her past suffering.

In the main story, Kidoumaru is subjugated and enslaved by Aoba Wakura.

Under Aoba’s domination, he is forced to act as her servant and loses his original freedom.

This reversal of roles—an infamous destroyer turned into a subordinate—adds a twist to his character.

Despite his power, he exists for a time as a controlled weapon rather than an independent threat.

During the battle at the hidden village, Kidoumaru initially fights one-on-one against Kyouka Uzen.

This confrontation is both a physical clash and a showdown rooted in their shared history.

However, the fight is interrupted when Shikoku suddenly intervenes.

Shikoku’s interference becomes the turning point in Kidoumaru’s status.

Breaking Free from Control

Due to Shikoku’s intervention, Kidoumaru is released from Aoba Wakura’s control.

Freed from her domination, he immediately turns on his former master.

Kidoumaru injures Aoba Wakura and then shifts his aggression toward Yuuki Wakura and Kyouka Uzen.

With his will restored, he becomes even more dangerous, driven purely by his own violent instincts.

Clash with Yuuki and Kyouka

In response, Yuuki Wakura and Kyouka Uzen enter a slave state, enhancing their combat abilities.

In this empowered form, they confront Kidoumaru head-on.

Despite his strength and newfound freedom, Kidoumaru is gradually overwhelmed by the combined might of Yuuki and Kyouka.

The battle becomes a test not only of power, but of their resolve to put an end to the monster who caused so much pain.

The fight culminates with Kyouka Uzen unleashing her sword technique “Mildare Yamazakura”, translated as “Raging Mountain Cherry Blossoms.”

This technique consists of a flurry of rapid, slicing attacks.

Kidoumaru is riddled with cuts and sliced apart by this technique.

Unable to withstand the onslaught, he collapses and is decisively defeated.

His fall represents the closure of Kyouka’s long-standing grudge and the end of a major threat.

The once-feared “One-Horn” who devastated a town is finally brought down by the very people he wronged.
