The martial art that Akaza once studied, "Souryuu," is a style that involves subduing opponents with bare hands.

that is"A fist to protect, not to hurt"It was.

Meeting the master and days at the dojo.
The reason he wanted to become stronger wasTo protect KoyukiIt was.

Regret for not being able to protect anything, and the fist of atonement

Having lost Koyuki and his master's dojo, Komaji could not forgive himself.

At that time, he met Muzan and gained eternal life as a demon.By pursuing "strength," I continued to run away from "weakness"That's why.

However, in the end, he showed his fist, not to others, but to himself.
"I was the weak one"The moment he realized this, he was probably saved.

The scene where Akaza blames himself

The "important person" I couldn't protect,
The "master" who trusted me,
The "dojo" that the master cherished,
And a promise to keep it forever.

At that moment when he carried all of that on his shoulders and punched himself, I saw Akaza not just as a villain, but as a person who lived with regret and love, and it really stirred my emotions.

🧭 Meaning and origin of the name Akaza

Keizo's lines hint at the "komainu"

"Oh, I see. Your name is Komaji. You're the 'Koma' of the guardian lion dogs."

-- Master Keizo

師範の慶蔵が、狛治の名前についての漢字を訪ねている様子

This one word gives Komaji the symbolism of "guardian (komainu)."
Although they exist to protect, they do not fight and defeat the enemy - they are truly "watchers."

The title of episode 155, "Useless Komainu" is the deciding factor

鬼滅の刃 第155話 役立たずの狛犬
Demon Slayer: Kimetsu no Yaiba Episode 155: Useless Komainu

The subtitle of the original story, episode 155, is"Useless Komainu".

The title itself points to the painful self-awareness that Komaji, as a human, had when he was unable to protect what he had sworn to protect.Akaza = "someone who was born to protect but was unable to do so"“This interpretation among fans has become established as the story structure.

The connection between the name "Useless Komainu" and "Akaza"

Keizo's line, "It's a 'koma' of a lion dog," is a prelude,
In terms of story structure “The symbolism of "komainu" is directly linked to the title of episode 155 We are doing it.

In other words:

conceptmeaningPosition in the story
KomainuSymbol of protection and faith"The Protector"
UselessThose who could not protectA symbol of loss
Sagittarius"A demon who had the power to protect but was unable to do so"Ironic Sublimation of the Komainu

Due to this structure, the transformation from Komaji to Akaza is

“"The name of someone who had the power to protect but was unable to do so"

At the same time, I think it also represents the "soul of someone who continued to hold on to the feelings they wanted to protect."

  • Komainu symbolism:The one who protects / but couldn't protect (useless guardian dog)
  • Literal aftertaste:"猗" = gracefulness and tranquility, "沟" = nest and place to live
    A person who has kindness but has lost their place

The sight of him smiling with Koyuki under the fireworks represents the peace the "Komainu" has finally reached at the end of its long journey.

It could be said that this is the moment when the name regains its meaning.

🌸 Reunion with Koyuki and salvation

"That's enough, Komaji-san."

"It's okay, Komaji-san" -- these words from Koyuki are forgiveness itself.
Komaji, who was meant to protect but couldn't protect,“Not "strength" but "kindness"”It will return to.

鬼滅の刃 無限城編|恋雪と猗窩座(狛治)が涙ながらに再会し抱きしめ合うシーン。「もういいの、狛治さん」と慈愛に満ちた抱擁。

This reunion is the core of what Demon Slayer has been depicting."People want to protect others"--Condensation.
The vow made under the fireworks, "I will protect you for the rest of my life," finally brings peace.


The past that could not be protected and the desire to protect it.
When the two embraced, Komaji was saved.

After a long period of loneliness and suffering, he is no longer a demon.As a personI think I shed a tear.

🔖 Summary

The movie "Demon Slayer: Kimetsu no Yaiba - Mugen Castle Arc Chapter 1: Akaza Returns" is
It was a story of love and vows that was impossible to watch without shedding tears.

Komaji and Koyuki's desire to protect.
I felt that this was the core of this work and the world of Demon Slayer itself.
