男はつよくなくてはと
きょうもだれかが　いうけれど
たたかうために　いきてゆく
それでいいのだろうか
わるいやつらを　やっつける
それはだいじな　ことだけど
いつかぼくにも　ほんとうの
つよさがわかる　きがするよ
マルス　マルス　あなたはやさしいこ
マルス　マルス　それでいいのよ

Otoko wa tsuyokunakute wa to
Kyō mo dare ka ga iukeredo
Tatakau tame ni ikite yuku
Sorede ī nodarou ka
Warui yatsura wo yattsukeru
Sore wa daijina kotodakedo
Itsuka boku ni mo hontō no
Tsuyosa ga wakaru kiga suru yo
Marusu! Marusu! Anata wa yasashī ko
Marusu Marusu sorede ī no yo

"A man has no need for tears"
That's something someone told me today.
So I live to fight
But is that really enough?
I'm going to fight ... all the bad guys
That's a very tough thing to do
But someday I'll find my true strength
I'm gonna find out how strong I really am.
Mars, Mars, you're so sweet.
Mars, Mars, you're doing great.
