To Light

To Light is the title of the song that both Sāra and Sēramu sang in Naruto Shippūden 4: The Lost Tower.

Japanese Lyrics
To takaku noboru hikari, wakitachi taru omo hi, mamoru beki ryu no michi yo, shi na hasha tsu sora o aogi.

Suna, kaze, ara koto mo, sagi kokoru koko no hi yo hana ni ma ichira.

Hasenu ni tsutayu hikari, ryu no te wo tatsu niwa e, hagishiki no omo kage yo, to wa no uta wo kokoro tsunaii.

Te na, na wa, na to uto mo, moe sagaru mane no hi yo yami wugirisa ga.

To takaku noboru hikari, nakaru ru toki kioku, haya mubeki ikiru michi wo, yume ni ikiru sora o aogi.

English Lyrics
The light rising above the tower, thoughts boil and run high, dragon path to be protected, pierce with shining blade look at the sky.

Sand, wind may rage proud blossoming, bright sun dance in flowers and never will it die.

The light flowing in spirals, to the garden where the dragon's claws ends, shadows of the olden days...

Trivia

 * The song seems to have references about the Rasengan, as the "light flowing in spirals".
