LyricsEdit

Japanese (日本語歌詞) Romaji (ローマ字)
思い出していたのは また、家族の事 omoi dashite ita no wa mata, kazoku no koto
「アヤノはお姉ちゃんだから 皆の事、よろしくね」 "ayano wa onee-chan dakara mina no koto, yoroshiku ne"

赤煉瓦の壁 小さな家の中で aka renga no kabe chiisana ie no naka de
ひそひそ話そう 秘密の作戦みたいに hisohiso hanasou himitsu no sakusen mitai ni
連れて来られた 三人の真っ赤な目には tsurete korareta sannin no makka na me ni wa
大人に隠していた 過去がある otona ni kakushite ita kako ga aru

怯えた顔で「僕は化物だから」 obieta kao de "boku wa bakemono dakara"
私は告げる「そんなことはないよ」って watashi wa tsugeru "sonna koto wa nai yo" tte
「真っ赤な色は主人公の色だから、怯えていなくても、良いんだよ」 "makka na iro wa shujinkou no iro dakara, obiete inakute mo, iinda yo"

面白い事 悩んでは 今日もお姉ちゃんぶって omoshiroi koto nayan dewa kyou mo onee-chan butte
「ほら、見ていて」 赤いマフラー巻き付けた "hora, mite ite" akai mafurā makitsuketa
『秘密組織みたい!』 『himitsu soshiki mitai!』

茜色、染めて、始めよう 小さな「ヒーローのフリ」だけど akaneiro, somete, hajimeyou chiisana "hiiroo no furi" dakedo
「少しでも、また笑えたら」って 今日も家族でいよう "sukoshi demo, mata waraetara" tte kyou mo kazoku de iyou

「幸せ」を願おう、先にある未来が どれだけ 悲しくても "shiawase o negaou, saki ni aru mirai ga dore dake kanashikute mo
「このことは秘密だよ」 楽しくて陽が沈んだ "kono koto wa himitsu da yo" tanoshikute hi ga shizunda

春風巡り 大人になった世界は harukaze meguri otona ni natta sekai wa
理不尽に曲がる 誰かの陰謀みたいに rifujin ni magaru dareka no inbou mitai ni
膨らんで消えた 愛する人の涙は fukurande kieta aisuru hito no namida wa
誰も気付けなくて、黒くなる dare mo kizukenakute, kuroku naru

狂い出していた 気付いたらもう kurui dashite ita kizuitara mou
誰にも言えなくて darenimo ienakute
「嫌だ、嫌だよ。壊れるのは」 "iya da, iya da yo. kowareru no wa"
幸せの終わる世界が来る shiawase no owaru sekai ga kuru

「茜色、お願い。これ以上、誰かの未来を壊さないで」 "akaneiro, onegai. kore ijou, dareka no mirai o kowasanaide"
泣きながらまた、考える 笑顔に隠したまま nakinagara mata, kangaeru egao ni kakushita mama

「赤目色、それが私なら 誰かの未来を救えるかな」 "akameiro, sore ga watashi nara dareka no mirai wo sukueru kana"
不器用で、情けない 独りぼっちの作戦だ bukiyou de, nasakenai hitoribocchi no sakusenda

私が消えた あの日の秘密組織は watashi ga kieta ano hi no himitsu soshiki wa
ちゃんと笑って 暮らせているのかな chanto waratte kurasete iru no kana
きっと、私は怒られちゃうなぁ kitto, watashi wa okorare chau nā
だけど、ちゃんと「お姉ちゃん」になれたかな dakedo, chanto "onee-chan" ni nareta kana

思い出してみよう あの好きだった言葉 omoi dashite miyou ano suki datta kotoba
「幸せ」ってなんだか不思議 "shiawase" tte nandaka fushigi
明日のこと、好きになれる ashita no koto, suki ni nareru
