1. Unhappy? 悩める人の子よ Unlucky? 人成らざる者も Be happy! 弛まず目指せよ

Romaji: Unhappy? nayameru hito no ko yo / Unlucky? hito narazaru mono mo / Be happy! tayumazu mezase yo

Cultural Nuance: Whether you're an unhappy human or an unlucky monster, don't give up—aim for happiness and keep charging forward!

🗣 Japanese Insight From the very beginning, this song declares itself an anthem for "everyone." "Hito no ko" (Child of man) refers to us humans. "Hito narazaru mono" (Those who are not human) is a classical and prestigious expression referring to entities that transcend or fall outside of humanity, such as ghosts, spirits, gods, or vampires.

"Tayumazu" (弛まず) means to keep going without slackening one's effort or losing focus. Whether you are human or a monster, do not stop striving for happiness—this encapsulates the theme of "self-responsibility and salvation" that flows through the core of the Monogatari series.

2. 不幸に甘んじて 満足するなよ 幸せになろうとしないなんて卑怯だ

Romaji: fukō ni amanjite / manzoku suru na yo / shiawase ni narou to shinai nante hikyō da

Cultural Nuance: Are you settling for being unhappy? Being satisfied with not even trying to find happiness is just being a coward.

🗣 Japanese Insight This is the most powerful and piercing punchline in the song.

"Amanjiru" (甘んじる) means to give up and accept an unsatisfactory current situation as "just the way it is," and even becoming comfortable in that miserable state. In Nisio Isin's world, using unhappiness as a shield to stop trying is judged as "Hikyō" (卑怯)—meaning cowardly or dishonest. It is a harsh yet encouraging message: even if you have a past where you felt "dead" (UNDEAD), living means constantly updating who you are now.

3. 次は鬼が出るか蛇が出るか 出会って遭ってやっと始まる物語

Romaji: tsugi wa oni ga deru ka ja ga deru ka / deatte atte yatto hajimaru monogatari

Cultural Nuance: Who knows what happens next? Whether it’s a great encounter or a terrible disaster, that’s when your own story finally begins.

🗣 Japanese Insight "Oni ga deru ka ja ga deru ka" (Will an ogre appear or a snake?) is a Japanese proverb. It refers to a thrilling yet scary situation where what happens next is completely unpredictable.

Note how two different Kanji are used for the word "Deatte/Atte" (To meet/encounter):

• 出会う (Deau): To meet a person by chance or by appointment.

• 遭う (Au): To face an unwanted event, such as an accident or disaster.

Life is a series of both wonderful encounters and terrible disasters. Nisio Isin’s philosophy is that only by accepting both does your "story" truly start to move.

4. 閑話休題 ピースピース

Romaji: kanwakyuudai / piisu piisu

Cultural Nuance: Enough small talk. Now, let’s get back to the main point. Yeah, peace peace!

🗣 Japanese Insight "Kanwakyuudai" (閑話休題) is a four-character idiom frequently used by the series' protagonist, Koyomi Araragi, and the pivotal character Yotsugi Ononoki. It’s a conjunction meaning "let’s put the idle talk aside and return to the main subject." In this song, it functions as a switch that instantly shifts the mood after a chaotic buildup.

The following "Piisu piisu" (Peace peace) is the catchphrase of Yotsugi Ononoki, a corpse doll oddity. This phrase, delivered by a character who lacks emotion, adds an eerie yet pop "UNDEAD" flavor to the track.

5. 既視感とテンプレで食傷

Romaji: kishikan to tenpure de shokushō

Cultural Nuance: It’s all just scenes I’ve seen before and predictable patterns—I’m totally fed up and sick of it.

🗣 Japanese Insight "Kishikan" (既視感) means déjà vu, and "Tenpure" is short for "template" (formulaic/cliché).

"Shokushō" (食傷) originally means "to be sick of eating" or to have food poisoning, but it is figuratively used to mean "being bored and fed up because the same thing keeps happening." For an "UNDEAD" being who has lived for centuries, the world feels like a repetitive cycle. Expressing this boredom as a physical discomfort like "food poisoning" is a brilliant touch.

6. 積んだ経験の因果 形骸化された神話と退屈な進化

Romaji: tsunda keiken no inga / keigaika sareta shinwa to taikutsu na shinka

Cultural Nuance: All the experiences piled up over time are just hollow legends now. There’s no excitement left in this world that's evolved into something so boring.

🗣 Japanese Insight "Keigaika" (形骸化) refers to a state where the original meaning or substance is lost, leaving only a hollow shell or form. Even beings once feared as "vampires" or "gods" have, in the modern era, been reduced to mere old rules or empty stories (myths).

Hidden behind these difficult words is the poignant cry of oddities who still seek excitement and want to shine as "individuals" in a world that has undergone such a dull evolution.

7. 古今東西 一切合切 森羅万象 ピースピース

Romaji: kokontouzai / issaigassai / shinrabanshō / piisu piisu

Cultural Nuance: Anytime, anywhere, every single thing, swallowing up every event in this universe... okay, peace!

🗣 Japanese Insight Three massive four-character idioms are piled up during the song's climax:

• Kokontouzai: All times (past to present) and all places (East to West).

• Issaigassai: Absolutely everything, without exception.

• Shinrabanshō: Everything in the universe, from physical objects to phenomena.

By encompassing time, space, matter, and events, and then ending with a lighthearted "Peace peace," the song creates a gap between its grand scale and its playful tone. This is the true essence of the Monogatari series and YOASOBI’s "UNDEAD."

🎤 Emotional Summary

The word "UNDEAD" carries a powerful will: not just "not dead," but "having overcome death to continue updating the present."

While confronting your past self (your ghost) and dealing with permanent labels or complexes, ikura’s voice pushes you—sometimes bluntly, but always warmly—to "aim for a happy ending." Perhaps we all live carrying our past selves as a form of "UNDEAD."

Whether you soak in your own misery or choose to be happy, it’s all up to you. With the whole universe on your side, let’s survive this "story full of monsters" with a peace sign. What YOASOBI and Nisio Isin have presented is a cruelly positive "spell" for living in the modern world.
