Lyrics Breakdown
Intro / Opening Lines
Japanese: Everydayが実験Day 痛いの痛いのとんでけって
https://j-lyric.net/artist/a0568fc/l065eb5.html
Romaji: Everyday ga jikken Day, itai no itai no tondeke tte
English: Every day is an experiment day—“pain, pain, fly away.”
The opening sets up the “laboratory of love” concept. Healing is framed as both scientific experiment and magical charm, mixing kawaii imagery with childlike incantations.
Verse 1 – Diagnosing the Heart
Japanese: 君の心の痛みの原因は何？ちょーっと見せてみなさいっ！
https://j-lyric.net/artist/a0568fc/l065eb5.html
Romaji: Kimi no kokoro no itami no gen’in wa nani? Chotto misete minasai!
English: What’s the cause of your heartache? Come on, let me see it!
Ogura’s voice takes on a playful “researcher” role, blending intimacy with humor. Healing becomes interaction—a dialogue between character and listener.
Chorus – Healing Through Love
Japanese: 治癒治癒中… 思いっきりLOVEリカバリー 1234 Close your eyesで治癒治癒ちゅっ♡
https://j-lyric.net/artist/a0568fc/l065eb5.html
Romaji: Chiyu chiyu chū… omoikkiri LOVE rikabarī, 1234 Close your eyes de chiyu chiyu chu♡
English: In the middle of healing… full-on LOVE recovery—1234, close your eyes for a healing chu♡.
The chorus fuses cuteness with EDM repetition, turning “chu” (kiss) into a healing device. It redefines denpa-kei not as nonsensical, but as structured play that conveys affection and comfort.
Verse 2 – Research and Confusion
Japanese: 今週ずっとコンフュージョン どーすれば皆がハッピーな日々？
https://j-lyric.net/artist/a0568fc/l065eb5.html
Romaji: Konshū zutto konfūjon, dō sureba minna ga happī na hibi?
English: This week’s been nothing but confusion—how can everyone have happy days?
The verse reflects trial and error, with “research” as a metaphor for relational effort. Cute language (“CUTE future,” “thorns in the heart”) hides deeper reflections on how to heal emotional wounds.
Bridge – Naming the Light
Japanese: 名前を付けなくちゃどれがいいかな？
https://j-lyric.net/artist/a0568fc/l065eb5.html
Romaji: Namae o tsukenakucha dore ga ii kana?
English: I have to give it a name—what should it be?
Here, the song shifts from playful healing to existential questioning: how do we name emotions before they vanish? This aligns with Ogura’s voice-acting technique of embodying “characters” within music.
Final Chorus – The Experiment of Love
The climax blends denpa-style repetition with future bass drops, reinforcing the “Love♡Ratory” theme. Healing is no longer just treatment—it is love as a laboratory experiment, endlessly repeated and playfully reinvented.
