剣(つるぎ)と盾 奉げる 
何時の日にか 貴女の為 

背伸びし 光求め 

もう願いも 祈りも 

いつでも 潔(しろ)い侭で

sakihokoru kono aoi hana
tsurugi to tate sasageru
itsuno hinika anata no tame
tatoe konomiga kudakare youtomo

takai kigi ni kakomarete
senobishi hikarimotome
ano yakusoku wo hatasu tame
azawaraware temo modotteyuku

kuzureta shiro ni wa
mou anata ga inakute
mou negai mo inorimo

sono mega akaku somerareta
to iu no nara
kono tsurugi de subete
tadashiide miseru madeda

Itsu demo shiroi mamade
anatawo matte iru
mukashi no sugata de
mata aeru miseru himade.

The blue flower that blossomed
By dedicating this sword and shield 
For you, sometime,
Even if my body scatters

Surrounded by tall trees 
I must obtain the light from it
To keep the promise we had
I must return even if I get scoffed at

In the broken castle, 
there is no more of you
Now neither the prayer nor the hope matters
If your eyes had turned red
With this sword I will change everything back to how it was

I am always waiting for real you
Until the day we meet again like how we used to be.

Helpful Info

Although I prefer the original song, this song is quite a good remix with nice vocals! There are over 5 ranges of tempo for this song, so you may have to be careful of that, as well as the piano.

I mastered this in 6.0 and I forgot the charts after updating and remastering again. At first I don't want to because of the slide zzzzzz but the rest was fine. Would kill my touchscreen.
