Everyday put on my face metal mask
I'm not for myself. for others
always
cover my emotion under metal mask

Every time feel the frozen at my mask
my heart will be cold
more and more
still cover my emotion under metal mask

I can't breath
aching heart
but I'll stay calm
still now

I can stand for my someday
I can stand for my family
I can let you bring down by my blow fist
but I'm not going to do because 
I'll keep my precious everything

I can stand with my metal mask
I can stand with my family
I will be the hero of my universe
I will put on my face metal mask 
for my precious everything

Every night
clean up my metal mask
I'm not for myself for others
always
and I close my eyes under metal mask

I can't breath
aching heart
but I'll stay calm
still now

I can stand with my metal mask
I can stand with my family
I will be the hero of my universe
I will put on my face metal mask 
for my precious everything

I can stand for my someday
I can stand for my family
I can let you bring down by my blow fist
But I'm not going to do because
I'll keep my precious everything

I can stand with my metal mask
I can stand with my family
I will be the hero of my universe
I will put on my face metal mask
for my precious everything
