「『シンクロ』と言えば……
絶対絶命のピンチにのみ希に起こりうるダブルスの寄跡」
振り返れば いつも君がいた
その安心感が 俺を大胆にするぜ
１＋１が無限大
引き出される可能性
君がいて良かった
呼びかければ 振り向いてくれる
その無邪気な笑顔 不安を帳消しにする
１ｘ２で無敵になる
湧き立つ不屈の闘志
君がいて良かった
君の光が 俺に反射して
二人は一つに輝く
君の想いが 俺につながって
二人は一つになれるよ
俺とお前は ゴールデンペア
俺の夢は お前の夢さ
同じ夢を見てきた
お前がマイナスなら 俺はプラス以上になる
いつも頼りにしてるよ
別れができても 忘れはしないぜ
二人で一つだったこと
悔いの無いよう 全力で行くぜ
この試合こそ今までの生き様
これが最後のゴールデンペア
俺とお前はゴールデンペア
CLOSED EYE With my eyes closed I’ll think about you with my heart
CLOSED EYE I’ll bring the truth out of the darkness into the light
Without a second thought I devote my body to the swing of my racket
I’ll return my pure soul to you
Just as expected from the Trickster of the Court
But, no matter who’s role you take, you’ll never become the real thing
I’ll certainly defeat the real you, without fail
CLOSED EYE I’ll even see through the things I can’t see with my heart
CLOSED EYE It’s an evident THEORY I’ll grab with my own hands
My awakened sixth sense will tell me where you are going to move
I am complete focused on you
Your ILLUSIONs are splendid
But no matter which shape you’ll take, you won’t be able to imitate their mind
I won’t be fooled and I’ll find your real form
CLOSED EYE With my eyes closed I’ll think about you with my heart
CLOSED EYE I’ll bring the truth out of the darkness into the light
Without a second thought I devote my body to the swing of my racket
