Letra da Música Infinity de Back-on

We're never turning back! Tamerai kirisaku!
Momata tobidatsu mikai no kanousei
Daremo ga ka kara kirou shuusei
Darekato onaji nantei no way!

Kimi to te wo tsunai de fly! Ruuru nante kowasu
I am a new type!
Kono sora hiro garu hirai saigou let's go! It's show time!

Itsu mo kanjou teki ni hashiri tsuzuketai
Jibun to ni u manifeesuto kogete
Kangai teki ni mou o to jiyuuni theory
Tori ja tsumaranai darou!

Tobi wa ru koto naku sou hikari mata toku
Mamata tobi tatei no hikou omosen
You gotta show me ya attack
De show me kuchisaki nara get out of my way!

Dousenara jiyuu gatetai
Sou kimochi ga aru go kasu all the time!
Mata daremo mitai kotonai sekai wo sugurunda
Let's go now!

Itsumo jyou sen teki na jibun de itaikara
Ubou dato mora warattemo isa
Jyou ga teki ni ima wo ikitakute theory
Nante suku rebaii darou

Back off! Gack off everybody get down!
Bring it on! getto de rasu with a mashingan
Tadakai ni ruuru ha naku randamu
Tsukami toru no saso no teni freedom

Itsu mo kanjou teki ni hashiri tsuzuketai
Jibun to ni u manifeesuto kogete
Kangai teki ni mou o to jiyuuni theory
Tori ja tsumaranai darou!

Itsumo jyou sen teki na jibun de itaikara
Ubou dato mora warattemo isa
Jyou ga teki ni ima wo ikitakute theory
Nante suku rebaii darou
