"Anime" es el término que engloba a la animación japonesa, destacada por su estilo visual y narrativo distintivo. La música desempeña un papel fundamental en los animes, ya sea a través de sus bandas sonoras, música de fondo o temas de apertura y cierre. La música de anime abarca una amplia variedad de géneros, desde pop y rock hasta música clásica y electrónica. Además, muchos artistas japoneses han iniciado sus carreras musicales creando temas para animes. En resumen, la música de anime contribuye significativamente a crear atmósferas, emociones y sensaciones en la audiencia.
Cuatro albumes conforman la banda sonora de esta serie de animación: "Masta", "Playlist", "Departure" e "Impression". Como autores destacan Nujabes, Force of Nature, Tsuchie y Fat Jon, aunque también podemos nombrar a Shing02 y Minmi, ambos cantantes japoneses que interpretan el opening y ending respectivamente.
Algunas de las canciones no se encuentran en los álbumes oficiales. Tal es el caso de Obokuri Eeumi de Asazaki Ikue de su álbum "Utabautayun", y "San Francisco" de Midicronica para su álbum "#501" (ending para el episodio Nº26).
Sharp like an edge of a samurai sword
The mental blade cut through flesh and bone
Though my mind's at peace, the world out of order
Missing the inner heat, life gets colder
Oh yes, I have to find my path
No less, walk on earth, water, and fire
The elements compose a magnum opus
My modus is operandi is amalgam
Steel packed tight in microchip
On my arm a sign of all-pro
The ultimate reward is honor, not awards
At odds with the times in wars with no lords
A freelancer
A battle cry of a hawk make a dove fly and a tear dry
Wonder why a lone wolf don't run with a klan
Only trust your instincts and be one with the plan
Some days, some nights
Some live, some die
In the way of the samurai
Some fight, some bleed
Sun up to sun down
The sons of a battlecry
Some days, some nights
Some live, some die
In the way of the samurai
Some fight, some bleed
Sun up to sun down
The sons of a battlecry
Look, just the air around him
An aura surrounding the heir apparent
He might be a peasant but shine like grand royalty
He to the people and land, loyalty
We witness above all to hear this
Sea sickness in the ocean of wickedness
Set sail to the sun set no second guessing
Far east style with the spirit of wild west
The "quote-unquote" code stands the test of
Time for the chosen ones to find the best of
Noble minds that ever graced the face of
A hemisphere with no fear, fly over
The blue yonder where
The sky meets the sea
And eye meets no eye
And boy meets world
And became a man to serve the world
To save the day, the night, and the girl too
Some days, some nights
Some live, some die
In the way of the samurai
Some fight, some bleed
Sun up to sun down
The sons of a battlecry
Some days, some nights
Some live, some die
In the way of the samurai
Some fight, some bleed
Sun up to sun down
The sons of a battlecry
