Lyrics
English Translation

''a voice closer to me than any other but i couldn’t hear it at all (sister’s noise... i find it out...) much time had passed when you and i finally met face to face i’ll keep searching for ‘sister’s noise’ as i wander the corners of my soul (sorrow of your heart... i shoot it down...) with hearts as one, nobody can bring us down...!''

''the city quietly hid you away i finally found you in a place haunted by old memories miles away from reality i relived them again and was unable see the pain you were in''

''the dreams you left in my hands back then might tear me apart but your hopes & dreams are my everything! i’ll believe in ‘em till the end''

''“live life being true to yourself” i can’t express this enough (sister’s noise... i find it out...) as long as i remember that through misery’s endless rebirths then ‘sister’s noise’ will be able to reach me generating power from tears (sorrow of your heart... i shoot it down...) only our combined strength can strike down the suffering''

''one evening after school down my usual route i suddenly looked to the sky and recalled your kindness the look in your eyes made me realize it takes a lot of courage to see our own weakness''

''your warm hands are guiding me i’ll keep your hope & dreams alive no matter what! they will penetrate the shadows''

''the fire inside of me lights up my world (sister’s noise... i find it out...) i never stopped running, never stopped searching. now your dream will be reality i hear ‘sister’s noise’ affecting me now its boisterous existence tells me (sorrow of your heart... i shoot it down...) our unique bond will never be broken''

''“live life being true to yourself” i can’t express this enough (sister’s noise... i find it out...) as long as i remember that through misery’s endless rebirths''

''a voice closer to me than any other but i couldn’t hear it at all (sister’s noise... i find it out...) much time had passed when you and i finally met face to face i’ll keep searching for ‘sister’s noise’ as i wander the corners of my soul (sorrow of your heart... i shoot it down...) ’cause the connection’s made, i will make sure no one takes away the smile we share''

nobody will ever bring us down...!
