Saki no koto dore hodo ni kangaeteitemo
hontou no koto nante dare nimo mienai
kuuhaku kokoro ni nanika ga tsumatte
ayamachi bakari kuri kaeshiteta

ippo zutsu de ii sa kono te wo hanasazuni
tomo ni ayunda kimi ga iki tsuzuketeru kara
boroboro ni naru made hikisakareteitemo
ano toki no ano basho kienai kono kizuna

nagare yuku toki no naka ushina wanu you ni
sure chigai butsu katta hontou no kimochi
kokoro ni shimiteku aitsu no omoi ni
deaeta koto ga motometa kiseki

tachi domaru koto sae dekinai kurushisa no
naka ni mieta hikari tsunagatte iru kara
usotsui tatte ii sa namida nagashite ii kara
ano toki no ano basho kienai kono kizuna

ippo zutsu de ii sa kono te wo hanasazuni
tomo ni ayunda kimi ga iki tsuzuketeru kara
boroboro ni naru made hikisakareteitemo
ano toki no ano basho kienai kono kizuna


Translation:

kizuna(bond)

Even if i think about the future as much as I can,
It's impossible for a person to see the real future
Some thing gets stuck in the gap of my heart
I just keep on making errors

It's okay if it's one step at a time, just don't let go of my hand
The steps that we took together, you are going to keep on living
Even if I keep on withdrawing until I crumble,

The bond of that time, that place, will never disappear

Inside the flowing time, I Try not to lose anything
The real thoughts that collide when we pass by
Her feelings that soaked in her heart
Our encounter was the miracle that i seeked

The pain that refuses to stand still
The light that's seen inside is always connected

It's okay if you lie, You can let your tears flow
The bond of that time, that place, will never disappear

It's okay if it's one step at a time, just don't let go of my hand
The steps that we took together, you are going to keep on living
Even if I keep on withdrawing until I crumble,
The bond of that time, that place, will never disappear
