“Where Our Blue Is (青のすみか)” by Tatsuya Kitani became one of the defining anime songs of 2023 as the opening theme for Jujutsu Kaisen Season 2 — Hidden Inventory / Premature Death Arc (懐玉・玉折).

Rather than focusing on curses and destruction, Kitani chose to portray the tragedy of youth through the image of an endlessly clear blue sky.

But in Japanese culture, “Blue (Ao)” symbolizes:

• youth and immaturity

• emotional purity

• memories too beautiful to touch again

The emotional centerpiece of the song is the double meaning of:

“Sundeiru.”

• 棲んでいる → “to dwell/live within”

• 澄んでいる → “to remain clear and pure”

The memories of youth still live inside the heart while remaining painfully clear forever.

This duality reflects the emotional relationship between:

• Satoru Gojo

• Suguru Geto

Two people who once understood each other without words but slowly became unable to hear each other’s silence.

The true “curse” in this song is not supernatural.

It is growing apart.

With explosive guitar rock, school-chime motifs, and cosmic imagery, “Where Our Blue Is” transforms youth into something eternal, devastating, and untouchable.

📝 Q&A for "Where Our Blue Is" (Ao no Sumika)

🟦 Q1. What is the significance of the "Blue Season" (Ao no Kisetsu) in this song?

A: In Japanese, "Ao" (Blue) is the root of the word for youth, "Seishun" (青春 - Blue Spring). However, in this song, "Blue" represents both the brilliant, infinite sky of their high school days and the "unripe" immaturity of their hearts. The "Blue" is described as "Sunde-iru"—both "crystal clear" (澄んでいる) and "haunting like a ghost" (棲んでいる). It suggests that for Gojo, the memory of that summer is a beautiful paradise, but it is also a permanent curse that he can never truly leave behind.

🦗 Q2. How does the "Cicada Rain" (Semishigure) relate to their friendship?

A: "Semishigure" (蝉時雨) refers to the deafening, collective chirping of cicadas in the peak of summer. The lyrics use this "noise" as a metaphor for the distractions of youth. While they were busy being "the strongest" and enjoying the chaotic energy of summer, Gojo failed to hear the "Silence" (Chinmoku) of Geto’s suffering right next to him. It captures the tragic irony that the very brightness and noise of their happiest days were what blinded (and deafened) Gojo to his best friend's descent into darkness.

🌸 Q3. What does it mean to call a person a "Fruitless Flower" (Adabana)?

A: "Adabana" (徒花) is a poetic term for a flower that blooms beautifully but withers without ever bearing fruit or seeds. By calling Geto an Adabana, the song acknowledges that his path—his rebellion and eventual death—was beautifully sincere yet ultimately tragic and "useless" in a traditional sense. It reflects the Japanese aesthetic of "Chiru" (散る - scattering like petals), where there is a profound, respectful sadness for a life that burned brightly and disappeared without a happy ending.
