RED

RED is the opening theme for Kagerou Daze -in a day's- performed by GOUACHE, a band Jin is in. The music video is a compilation video directed by Toushi Atsunori. The song was released as a single on November 4th, 2016.

Background
During the second Q&A segment of the Yuukei Roadshow in Tokyo event, Jin was asked what the song introductions for days, daze and RED were. While he was undecided on days and daze since they were only intended as the theme songs for Mekakucity Actors, he described RED as a "A story that changes eye color" or "A story about a change of eye color." He stated further, "There’s image of two friends - one who likes playing and one who prefers to study. The song about awareness that the other one has became an adult, as if color of his/her eyes has changed: 'with those eyes of yours, dyed in a colour I’ve never seen before.'”

Lyrics & Translation
だんだん目が回って 夕焼けが燦々 空に散って行った 滲み出す雲に 言葉が出なくなるのは何故？
 * -|Kanji=

遠回りの近道と 廃り 果てた線路 湿った手を掴んだまま 速足で進む

互い違いの畦道が 水みたいに揺らいで 蝉の音を暈したまま 立ち尽くしていた

夏が昨日を 通り越して行く 草の匂い 俄雨の温度 混ざり合ったら

僕らが今日まで 知らない日々は 数えきれない 鱗雲の奥で 確かに呼んでいる

泥に塗れた 僕の手を拒む様に 「難しい」ってはにかんだ 君と僕とじゃ違うから

だんだん目が回って 夕暮れが燦々 空に散って行った

思い出す程に言葉が出なくなるのは何故？

道連れに賛成なら笑って 疾っくに遠く離れた 君はただ

見たことの無い色に染まった瞳で あぁ、瞬きの一つもしないまま

大人なんかには解らない色を見ている

あぁ、融け落ちて往く 燃ゆる日の秘密を 鮮やかに綴じ込めて 忘れよう 色褪せぬように もどかしさと一緒に 思い出してしまわない様に

遠回りの帰り道に 通り風が吹いて 一人ぼっちのサイレンが 響いては消える

変わり果てた蝉達の 叶わなかった想いを 終わった夏の正体を 僕たちは知らない

西日の奥から 太陽の影が這っていく 暮れ泥んでいく今日が もう少しで終わるから

だんだん目が回って 夕映えが燦々 目に滲んで行った

当然だったのに涙が落ちていくのは何故？

約束は さんざっぱらに舞って 疾っくに遠く離れた 君はもう

僕も同じ色に染まって 忘れよう あぁ「さよなら」の一つもしないまま 大人なんかには解らない色を見ていた

今日の日のことも Dandan me ga mawatte Yūyake ga sansan sora ni chitte itta Nijimidasu kumo ni kotoba ga denaku naru no wa naze?

One by one, our eyes will turn To the red sunset’s glow as it scatters through the sky The clouds seep, but Why won't the words come out?

Detours and shortcuts A route where the waste will come to end Clutching sweaty palms, We march forward in hasty steps

The path between rice fields wavers like water As the sound of cicadas grew fuzzy, we stood frozen

We travel beyond the summer of yesterday The intertwined smell of grass, And temperature of a rain shower

Countless unknown days Within the cirrocumulus clouds, We were surely calling out-

As if to reject my mud-coated hand, “It’s too difficult,” you shyly said Well, you and I are different after all

One by one, our eyes will turn To the red sunset’s glow as it scatters through the sky As the memories are recalled Why won't the words come out?

I laugh as my companions give approval, The ones I was parted from so long ago, so far away You looked on with eyes Dyed a color never seen before

Aah, without even a single blink I watched that color The one that grown ups will never understand

Aa, I'm going to melt down

(Burn those days of secrets) I shut it in vividly (I will forget it all) So that color won't fade away (With frustration) I won't remember in the end

We detour during the treck back home The passing of the whistling wind A lonely siren resounds only to vanish

The cicadas changed completely Desires that did not come true As summer’s true colors ended, We had no clue

The intensity of the setting sun as its shadows creep Today we will go to the end Just a little bit longer until it's over

One by one, our eyes will turn To the red sunset’s glow as it blurs It was only natural, and yet Why are the tears falling?

The terrible promise is spinning I wave my hands, yet you had already gone far away Now I am stained the same color Let's forget

Aa, such a lonely goodbye One that grown-ups would never understand And I watched the color Today as well
