Guess that song!

Hey everyone, like I said, we're starting with a Bleach game! So I chose, guess that song, because last time... on Bleach shrine.... We played "Who's line is it anyway?!"
So here are the lyrics!

LYRICS :

Kodomo no goro ni modoru yori mo
Ima wo umaku ikite mitai yo
Kowagari wa umare tsuki

Hi no atari basho ni dete
Ryoute wo hirogete mita nara
Ano sora koete yukero ka na?
Nante wo ita na
Tobitatsu tame no tsubasa
Sore wa mada mie nai
KANTAN ni ika nai ka ikite yukeru

There are the lyrics! Give a good guess!

By the way, posting the artist is optional!
