おかしいよ
痛みに哀れ人
かつて立ってた
地面に落ちてた
アー、悲しいかな
モノに同情じゃない
急に
瞬間のためのに
避けられない
涙をぬぐいた
行軍したセンターに
「賽は投げられた！」
砲丸は真上
ムードに盛り上げたなえに
降る雨
味方撃墜さ
一人ぼっちんだ
気まぐれなデジャヴね
振り返っては
「戻れないからだ。」
傷ついても
進める人を
感心しました 
こんな見るのは心苦しい
救えない
戦いを続き
急に
瞬間のためのに
避けられない
武器を落とした
無防備だった
「賽は投げられた。」
戦いの誰かがつぶやいた
結局落ちた
味方撃墜さ
一人ぼっちんだ
運命もしかしたら？
左を見て
笑顔で 言って
「さよなら。」
「賽は投げられた、」
残念に言った
突然 空が明るくなった
「賽は投げられた。」 (YES！)
喜びましょう (YES！)
みんな力を入れる
一々ヒットに
残されたもの
sweet memories
わざと武器を落とした
大声で
「Free me！」

I find it funny,
those who pitied my sorrow
were once standing,
but are now laying on loam
Ah, such a tragedy
... yet they don't deserve my sympathy
It felt so sudden,
even though we were led to this moment
It was inevitable.
Not long after I wiped away my tears,
I marched to the center
"Alea iacta est!"
Someone said as a cannon shot overhead
Meanwhile, evoked by the mood,
a storm conjures. 
With my allies shot down,
it leaves me in the open.
Isn't this a whimsical déjà vu?
Looking back to where we started
"There really is no going back."
I admire
those who push forward,
despite being hurt
It pains me to see them like this,
yet there's nothing I can do
except continue the fight.
It felt so sudden,
even though we were led to this moment
It was inevitable.
Not along after I dropped my weapon,
I was defenseless
"Alea iacta est."
Someone muttered while charging into battle,
only to fall
With my allies shot down,
I'm left in the open.
Perhaps this is what you meant all this time—my destiny
Looking over to my left,
with a smile they replied,
"Goodbye."
"Alea iacta est,"
Someone once said regrettably
And suddenly, the gray sky brightened
"Alea iacta est!" (YES!)
Enjoy this time (YES!)
Everyone puts forth effort
into each and every blow
All that was left of me
were these precious memories
As I drop my weapon on purpose,
I shout,
"Free me!"
