1. 痛みの数だけ それは、僕の静脈を通り 心臓を突破して 忘れた頃、到達 脳に

Romaji: Itami no kazu dake sore wa boku no jōmyaku o tōri shinzō o toppashite wasureta koro tōtatsu nō ni
Cultural Nuance:
“As many wounds and pains as one has endured, those memories seem to travel through the veins, pass through the heart, and—just when they are nearly forgotten—reach the brain as a form of unerasable resolve.”

🗣 Japanese Insight:
This line vividly visualizes the psychological shock of past “pain” through the anatomical imagery of blood circulation—a hallmark of Vaundy’s striking sensibility. The path from jōmyaku (veins) to shinzō (heart) to nō (brain) suggests that pain is not a fleeting emotion but something that dissolves into the body’s deepest systems.
The phrase “wasureta koro tōtatsu” (“reaching you when you’ve forgotten”) resonates with realism: after the panic of being hurt fades and daily life resumes, the true meaning of pain and the impulse for transformation suddenly seize the mind.

 It evokes the heavy, serious beginning of Yuru’s journey—turning the trauma of his destroyed village into the energy that drives him into the outside world.

2. うらみわびの隙間風は 許してくれ

Romaji: Urami wabi no sukimakaze wa yurushite kure
Cultural Nuance:
“Please forgive the cold wind that blows through the cracks of a heart worn down by resentment toward others and the sorrow of one’s unfair circumstances.”

🗣 Japanese Insight:
Urami wabi is thought to derive from Fujiwara no Sadayori’s waka in the Ogura Hyakunin Isshu:
“Urami wabi hosanu sode dani aru mono o.”

 It describes a state in which one is exhausted from prolonged resentment, leaving the heart frayed and fragile.
Vaundy likens this heavy emotion to a cold draft seeping through the cracks of a house—sukimakaze.
Behind the heroic resolve to “fly,” lingering attachments and dark emotions remain. The whispered “yurushite kure” (“forgive me”) gently lifts the protagonist’s human vulnerability, offering a line that deeply resonates with listeners.

3. この不甲斐ない 僕の言葉も涙も全部

Romaji: Kono fugainai boku no kotoba mo namida mo zenbu
Cultural Nuance:
“Even my useless words and helpless tears—none of which can change reality—are things I will carry with me as I move forward.”

🗣 Japanese Insight:
Fugainai describes a deep, introspective sense of weakness, disappointment, and powerlessness.
Facing the unknown world and overwhelming supernatural forces, the protagonist does not deny how “fugainai” his words and tears are. Instead, the word zenbu (“all of it”) shows his willingness to shoulder his imperfections.

 In many of Vaundy’s works, heroes are not invincible from the start. The true “moment of departure” lies in accepting one’s muddy, tear‑stained process as fuel for one’s wings.

4. 言葉の数だけ それは、あなたの神経を通り 脳幹を突破して 忘れた頃、到達 瞳に

Romaji: Kotoba no kazu dake sore wa anata no shinkei o tōri nōkan o toppashite wasureta koro tōtatsu hitomi ni
Cultural Nuance:
“The more words exchanged, the more they travel through your nerves, pierce the brainstem, and—when nearly forgotten—reach your eyes as a determined gaze toward the future.”

🗣 Japanese Insight:
In contrast to Phrase 1’s inward vector (“pain–me–brain”), this line forms an outward vector (“words–you–eyes”), highlighting relationships and the future.
Words passing through shinkei (nerves) and nōkan (brainstem) evoke the profound impact communication can have.

Ending at hitomi (eyes) is cinematic: words and promises become part of one’s being and eventually surface as the determined gaze that looks straight ahead.
It mirrors Yuru’s evolving eyes as he meets new people—and new “Tsugai”—in the outside world.

5. その鬱蒼としげる兵糧と退路

Romaji: Sono ussō to shigeru hyōrō to tairo
Cultural Nuance:
“The overwhelming provisions and resources that block the path ahead, along with the tempting escape routes always available.”

🗣 Japanese Insight:
Ussō to shigeru—originally describing thick, eerie overgrowth—is paired with hyōrō (provisions) and tairo (escape routes), creating a striking visual. 

Though Yuru has escaped his closed village, the choices before him and the temptation to retreat intertwine like a dense forest.

Both “provisions” and “escape routes” seem helpful, yet they can dull the will to challenge the unknown.
The phrase captures the battlefield‑like tension of breaking through one’s environment to seek the true path forward.

6. 擦り切れる突風が解廊

Romaji: Surikireru toppu ga kairō
Cultural Nuance:
“A harsh, skin‑scraping gust seems to tear open the darkness and reveal a corridor leading toward the future.”

🗣 Japanese Insight:
One possible interpretation is that Vaundy layers the sound of kairō (“corridor”) with the character 解 (“to release, to untie”), crafting a word that carries multiple resonances.

 First, it suggests a passage that “releases” a closed space, echoing Yuru’s escape from his sealed village.
Second, the wind “unties” tangled threads of fate, carving open a corridor toward the future.

 It conveys the fierce resolve required to break through one’s destiny.

7. 気分次第で生えた羽だって でも僕の翼だよ全部

Romaji: Kibun shidai de haeta hane datte demo boku no tsubasa dayo zenbu
Cultural Nuance:
“Even if these wings sprouted from a fleeting impulse, they are still my real wings that will carry me into the future.”

🗣 Japanese Insight:
This is the emotional climax of the song. What begins as hane (“wings that grew on a whim”) evolves into tsubasa (“true wings”) through the declaration “zenbu” (“all of them”).

 The song suggests that “flying” does not require perfect preparation. Even impulsive, imperfect beginnings become genuine wings when chosen by one’s own will.

 It mirrors the gritty yet noble characters in Arakawa’s works—those who move forward while carrying their pain.

🎤 Emotional Summary

Tobu Toki transcends the frame of an anime opening, becoming an anthem that celebrates the first decision of anyone stepping into an unknown tomorrow.

 It embraces human weakness—circulating pain, powerless tears—and transforms even impulsive wings into “all of my wings.” The gust that cuts through a closed world becomes a kairō, a corridor toward dawn. The message that the moment of taking flight—without any guarantee of success—is the most beautiful and precious continues to gently yet powerfully push the backs of those who struggle to take their next step.
