Bài hát: Infinity - Back-on

We’re never turning back! Tamerai kirisaku!
Ima, mata tobitatsu mikaitaku no kanousei
Daremo ga kako kara kidou o shuusei dareka to onaji nante No way!

Kimi to tewotsunaide Fly!!
RUURU nante kowasu I’m a New Type!
Kono sora hirogaru mirai saa ikou! Let’s go! It’s show time!!

Itsumo kanjou-teki ni hashiri tsuzuketai jibun to iu MANIFESUTO kakagete
Kankaku-teki ni motto jiyuu ni theory doori ja tsumaranai daro!?

Togireru koto naku sou hikari matataku! Ima mata tobitatte idomu koubousen
You gotta show me ya attack de shoumei kuchisaki nara get out of my way!

Dousenara tsuyo gatte itai...
Sono kimochi ga ugokasu All the time!
Mada daremo mita koto no nai sekai o tsukurun da let’s go now!

Itsumo chousen-tekina jibun de itaikara mubouda to warawarete mo ii sa!!
Chokkan-teki ni ima o ikitakute theory nante tsukureba ii daro?

BACK OFF! BACK OFF! Everybody get down!!
Bring it on!! Kechirasu with a MASHINGAN
Tatakai ni RUURU wanaku RANDAMU tsukami toru no sa sono te ni freedom

Itsumo kanjō-teki ni hashiri tsudzuketai jibun to iu MANIFESUTO kakagete
Kankaku-teki ni motto jiyuu ni theory-doori ja tsumaranai daro!?

Itsumo chousen-tekina jibun de itaikara mubouda to warawarete mo ii sa!!
Chokkan-teki ni ima o ikitakute theory nante tsukureba ii daro?
