The English lyrics for "Where Our Blue Is" by Tatsuya Kitani, the opening theme song for Jujutsu Kaisen Season 2, express themes of bittersweet farewells, friendship, and lingering emotions. The song uses "Blue" as a metaphor for a powerful bond and enduring feelings despite separation. Key excerpts from the English translation include:

• "Our blue still lives, our blue is still clear. No prayer or word could ever reach you, no matter how close they could get to you."
• "In such a color as if it were a silent love, or as if it were a summer rolling down a cheek."
• "I’ve got a curse word for you stuck in the back of my throat. It is the unvoiced voice that says 'We’ll see each other again, won’t we?'"
• "The sorrow behind your smile, all the way I’ve regretted missing it. To you, who bloomed and fell away as a fruitless flower, farewell."
• "Blue still lives in me, blue clear as the sea. Even though a single prayer, a single word could change our fates, I know it’s way too late to be heard."
• "Just like a love that could never quite reach, or just like the colors that run down my cheeks, forever burning."
• "I couldn’t even whisper to curse you, the words in my throat that I never spoke: 'You’re my one and only, best friend.' I wish I could have told you then."

The lyrics evoke a sense of nostalgic longing and the pain of parting from someone dear, framed within the imagery of blue as a symbol of connection and memory
