1. 貫けば 英雄に近づいた

Romaji: Tsuranukeba eiyū ni chikazuita

Cultural Nuance: I believed that if I could pierce through the enemy (with a bullet or blade), or if I could carry out my own will to the end, I would become a hero who achieved justice.

🗣 Japanese Insight: The verb tsuranuku (貫く) carries two meanings in Japanese: the physical act of a bullet piercing a target and the metaphorical act of sticking to one's convictions (as in the idiom shoshi-kantetsu). This phrase sharply points out how subjective and fragile "justice" is on the battlefield. "Piercing through" with one’s own camp’s will is merely "slaughter" from the opponent’s perspective, yet it is celebrated as "heroism" within one's own community—a chilling depiction of the distorted structure of war.

2. 同じ形 同じ体温の悪魔

Romaji: Onaji katachi onaji taion no akuma

Cultural Nuance: The existence I once hated as an enemy turns out to be a human being with the exact same shape and body temperature as me; and in their eyes, I am the "devil."

🗣 Japanese Insight: The word taion (body temperature / 体温) gives this phrase a raw, vivid reality. The enemy, who was nothing more than a "target to be defeated" from a distance, is revealed to be a "person" with the same warmth and love for their family once you are close enough to touch them. This reflects Eren’s despair upon discovering the world across the sea. It symbolizes the tragic irony that humans try to maintain their own sense of justice by labeling others as "devils," while failing to see their shared humanity.

3. 生まれてしまった 運命嘆くな

Romaji: Umarete shimatta unmei nageku na

Cultural Nuance: Do not grieve over the cruel and harsh destiny of being born as an Eldian or as a "child of the devil." Do not let it stop you.

🗣 Japanese Insight: A consistent theme throughout Attack on Titan is the fierce affirmation of existence: "We were born into this world, and that alone makes us free." The phrase nageku na (嘆くな) is a strong negative command, representing a heartbreaking resolve toward a self that has been rejected by the world. Eren views the fact of being born (umarete shimatta) not as a reason for regret, but as the starting point for his fight.

4. 帰る場所が なければ どこへも行けない

Romaji: Kaeru basho ga nakereba dokoe mo ikenai

Cultural Nuance: Even if you gain wings of freedom and the power to go anywhere, you cannot truly move forward unless you have a "place to return to" where your home and loved ones await.

🗣 Japanese Insight: True freedom is not simply wandering aimlessly. This lyric suggests that an "anchor"—a kaeru basho (place to return to, such as Paradis Island or the presence of Mikasa)—is what allows a person to venture out into the harsh external world. The irony is that in order to protect that singular "place to return to," Eren destroys the entire external world and steps onto a path from which he can never return.

5. 世界は残酷だ それでも君を愛すよ

Romaji: Sekai wa zankoku da / Soredemo kimi o aisu yo

Cultural Nuance: No matter how irredeemably cruel this world is—beyond its beauty—I will transcend that absurdity and simply continue to love you.

🗣 Japanese Insight: The paradox soredemo (Despite that / それでも) is the core of this song and the entire work. It is the final answer to the phrase "The world is cruel," which has been repeated since the first season. Eren’s motivation is no longer a grand cause like justice or world peace; it converges into a personal declaration of love for a single person. This implies the terrifying nature of love: a pure devotion that can justify even the most massive acts of violence against the rest of the world.

6. 選んだ人の影 捨てたものの屍

Romaji: Eranda hito no kage / Suteta mono no shikabane

Cultural Nuance: The dark shadow cast behind the people I chose to protect, and the cold corpses (shikabane) of the countless victims I discarded and trampled upon to make that choice.

🗣 Japanese Insight: Shikabane (屍) is not a word used in everyday modern conversation; it is a heavy, ominous literary term for a corpse often found in old war chronicles. The imagery suggests that if you choose "light" (the loved ones), a deep "shadow" is inevitably born, and at your feet lie the "corpses" of what you abandoned. To choose is synonymous with bearing the sin of killing. This line captures Eren’s hellish responsibility and his grim honesty in facing the pain he has caused.

7. 正義の裏 犠牲の中 心には悪魔の子

Romaji: Seigi no ura / Gisei no naka / Kokoro ni wa akuma no ko

Cultural Nuance: Behind the glorious justice spoken aloud, and in the midst of the piled-up sacrifices, a "child of evil"—myself—is truly pulsing within.

🗣 Japanese Insight: By the end of the song, the term "Akuma no Ko" is no longer an insult hurled by the world, but an identity that Eren has fully embraced. Moving beyond the debate of who is right and who is wrong, he recognizes himself as the devil who betrayed the world for the sake of love. This phrase echoes as an ultimate resolve—an absolute, solitary determination that needs no understanding from anyone else.

🎤 Emotional Summary

Ai Higuchi’s "Akuma no Ko" is a blood-chilling monologue of a young man who stripped away the mask of justice and chose the path of a "devil" for the sake of love. The piano melody is both gentle and ruthless, forcing us to face the truth we often ignore in our peaceful lives: that every choice comes with a sacrifice.

As the lyrics state, "Rightness is to strongly believe in yourself." Eren believed in his own rightness to the very end, and as a result, he became a "child of evil." That figure is undeniably cruel, yet it is also the ultimate image of a "human" struggling and gasping for the sake of freedom.
