— Website description[1]

"Roshin Yukai" (炉心融解 lit. Meltdown?) is a Kagamine Rin song written by kuma(alfred) and composed by iroha(sasaki).

Game appearances[]

"Roshin Yukai" first appeared in Hatsune Miku: Project DIVA 2nd where it was unlocked after clearing "Miracle Paint". It was also featured in Hatsune Miku: Project DIVA Arcade where it was added to the game on 24 February 2011. When the arcade game was updated to Hatsune Miku: Project DIVA Arcade Future Tone, an Extra Extreme difficulty rhythm game chart for the song was added on 17 July 2014 and is one of the few first songs to have the said difficulty when it was introduced. "Roshin Yukai" is also available in the PlayStation 3 port Hatsune Miku: Project DIVA Dreamy Theater 2nd with the exact same rhythm game and PV (albeit with updated high-definition visuals). It was featured later in Hatsune Miku: Project DIVA Extend (and Dreamy Theater Extend) where it can be unlocked by clearing "To the End of Infinity". It had the exact same PV and rhythm game from Project DIVA 2nd.

"Roshin Yukai" also made an appearance in Miku Flick/02 where it was available at the start of the game. The song was featured once again in Hatsune Miku: Project DIVA F 2nd where it was unlocked after clearing "Blackjack". Its PV was based on its earlier appearances but was slightly modified for a Chance Time Success Event. In Hatsune Miku: Project DIVA Future Tone, the song was included in the Future Sound song pack. It is also featured in Hatsune Miku: Project DIVA MegaMix in the Song Pack 1 DLC. Its PV was modified to include the ToonShader graphics, though its rhythm game charts from Project DIVA Arcade remain the same in Arcade Mode.

Lyrics[]

街明かり 華やか エーテル麻酔の冷たさ
眠れない 午前二時 全てが急速に変わる

オイル切れのライター
焼けつくような胃の中
全てがそう嘘なら
本当に よかったのにね

君の首を絞める夢を見た
光の溢れる昼下がり
君の細い喉が跳ねるのを
泣き出しそうな眼で見ていた

核融合炉にさ 飛び込んでみたいと思う
真っ青な光包まれて奇麗
核融合炉にさ 飛び込んでみたら そしたら
すべてが許されるような気がして

時計の秒針や テレビの司会者や
そこにいるけど 見えない誰かの
笑い声 飽和して反響する

アレグロ・アジテート
耳鳴りが消えない止まない
アレグロ・アジテート
耳鳴りが消えない止まない

誰も皆消えてく夢を見た
真夜中の部屋の広さと
静寂が胸につっかえて
上手に息ができなくなる

核融合炉にさ 飛び込んでみたら そしたら
きっと眠るように消えていけるんだ
僕のいない朝は 今よりずっと素晴らしくて
全ての歯車が噛み合った
きっとそんな世界だ

machiakari hanayaka ETHER masui no tsumetasa
nemurenai gozen niji subete ga kyuusoku ni kawaru

OIL gire no LIGHTER
yaketsuku you na i no naka
subete ga sou uso nara
hontou ni yokatta no ni ne

kimi no kubi o shimeru yume o mita
hikari no afureru hirusagari
kimi no hosoi nodo ga haneru no o
nakidashisou na me de miteita

kakuyuugouro ni sa tobikonde mitai to omou
massao na hikari tsutsumarete kirei
kakuyuugouro ni sa tobikonde mitara soshitara
subete ga yurusareru you na ki ga shite

tokei no byoushin ya terebi no shikaisha ya
soko ni iru kedo mienai dareka no
waraigoe houwa shite hankyou suru

ALLEGRO AGITATO
miminari ga kienai yamanai
ALLEGRO AGITATO
miminari ga kienai yamanai

daremo minna kieteku yume o mita
mayonaka no heya no hirosa to
seijaku ga mune ni tsukkaete

The city lights are spectacular, but I feel ether's lingering chill
I can't sleep, it's 2 AM, and everything's changing so fast

I'm like a lighter out of fluid
My insides are on fire
Sometimes I wish
It was all a lie

In my dream I strangled you
In the languid afternoon light
I watched your throat, thin and twitching
Through eyes brimming with tears

I want to jump into the core
Beauty wrapped in pure blue light
If I could jump into the core
I feel as if all would be forgiven

The second hand on a clock, a TV host
Someone there I just can't see
Their laughter echoes as it swells

Allegro agitato
The ringing in my ears won't fade, won't stop
Allegro agitato
The ringing in my ears won't fade, won't stop

I dreamed the whole world vanished
In the night, my room feels vast
And the silence chokes my heart
Making it hard to breathe

If I jumped into the core
I'd vanish, like I had gone to sleep
A morning without me would be perfect
All the gears everywhere meshing together
That's how the world would be

English translation by Kajiya Productions and 8-4

街燈 繁華 冰冷的乙醚麻醉藥
無法成眠的 凌晨兩點 一切急速變化

煤油耗盡的打火機
宛如灼燒的胃
如果一切都是謊言
那就 太好了

夢到我掐著你的脖子
灑滿陽光的午後
你那纖細的喉嚨輕顫
在我泫然欲泣的雙眼裡

好想飛身跳進 那個核心
被美麗的深藍色光籠罩
如果飛身跳進 那個核心
總覺得一切都能得到諒解

時鐘的秒針 節目主持人
雖然存在 卻不見人影的
笑聲 如雷貫耳的回音

Allegro・Agitate
耳嗎未消失 未停止
Allegro・Agitate
耳嗎未消失 未停止

夢到所有人都消失
深夜寬敞的房間
與寂靜刺入我心
無法順利呼吸

如果飛身跳進 那個核心
一定可以宛如熟睡般消失
沒有我的早晨 比現在更美好
所有齒輪都能吻合
世界想必就是這樣

Translation from Project DIVA F 2nd (Asia)
