Hagane no Kokoro

Fictional artists. Music and visuals made with generative AI.

Pain becomes a blade, tears become flames. "Hagane no Kokoro" is the heart of steel that gave Hagane Sakura 鋼の桜 its name.

This song represents the Steel Side of Hagane Sakura 鋼の桜 - a powerful expression of determination where the five members face fear, pain, and doubt together. "Hagane no Kokoro" means "Heart of Steel", a symbol of a spirit that can be wounded, tested, and shaken, but never broken.

Through Hikari’s commanding lead vocals, the bright harmonies of Hokori, the mature warmth of Mayu, the explosive rock energy of Sora, and Yui’s fierce rebellious presence, the song transforms struggle into strength. Heavy metal riffs collide with idol-style melodies, creating the unique contrast that defines Hagane Sakura 鋼の桜: sweetness and power, vulnerability and courage, softness and steel.

Lyrics

静かに…
息をして…
心を燃やせ…

Hey! Hey! Hey!
Stand up! Fight now!

闇の中で　目を開けて
震える手を　握りしめた
倒れても　終わりじゃない
涙さえも　刃になる

Ha! Ha!
Don't give up!
Ha! Ha!
Rise again!

小さな声が　叫んでる
まだ行けると　叫んでる
胸の奥で　火が灯る
Now we are ready to go!

鋼の心で　立ち上がれ
痛みを越えて　空へ飛べ
拳を上げて　break the night
夢のために　fight! fight! fight!

鋼の心で　前を向け
怖くてもいい　進めばいい
叫べ　wow wow wow
We are stronger now!

Sei! Sei! Sei!
心を燃やせ！
Sei! Sei! Sei!
Never back down!

傷だらけの　この道でも
迷いながら　走り出した
誰かの声　追いかけずに
自分の未来　掴みに行く

Go! Go!
Take your chance!
Go! Go!
Break your chains!

弱さだって　隠さない
怖さだって　抱きしめる
それでもまだ　立ち向かう
Now we are ready to go!

鋼の心で　立ち上がれ
痛みを越えて　空へ飛べ
拳を上げて　break the night
夢のために　fight! fight! fight!

鋼の心で　前を向け
怖くてもいい　進めばいい
叫べ　wow wow wow
We are stronger now!

倒れても！
Rise up!
迷っても！
Stand up!
泣いても！
Look up!
最後まで！

Are you ready?
Ready!
Can you fight it?
Fight it!
Can you make it?
Make it!
心で shout!

夜が長くても
光は消えない
胸に刻んだ
約束がある

一人じゃない
怖くはない
声を合わせて
We rise again!

鋼の心で　立ち上がれ
痛みを越えて　空へ飛べ
拳を上げて　break the night
夢のために　fight! fight! fight!

鋼の心で　前を向け
怖くてもいい　進めばいい
叫べ　wow wow wow
We are stronger now!

Sei! Sei! Sei!
心を燃やせ！
Sei! Sei! Sei!
Never back down!

Hagane no kokoro!
