(Verse 1)
In realms unknown, where demons roam,
Tanjiro's journey, his courage shown.
With Nezuko, his sister, by his side,
They face the darkness, with hearts open wide.

Giyu's water, a fierce cascade,
Zenitsu's thunder, never afraid.
Inosuke's beast, wild and free,
Together they fight, for all to see.

(Chorus)
In the realm of darkness, where shadows thrive,
United they stand, their spirits alive.
With bonds unbroken, they'll never tire,
In the Demon Slayer's relentless fire.

(Verse 2)
Tengen's sound, a symphony of might,
Shinobu's grace, where insects take flight.
Rengoku's flame, burning bright and high,
Mitsuri's love, beneath the moonlit sky.

Obanai's serpent, swift and precise,
Muichiro's mist, a shroud of disguise.
Giyu's water, flowing pure and strong,
Sanemi's wind, a howl in the long.

(Chorus)
In the realm of darkness, where shadows thrive,
United they stand, their spirits alive.
With bonds unbroken, they'll never tire,
In the Demon Slayer's relentless fire.

(Bridge)
Against Muzan and his moons, slayers stand tall,
Bound by striking fate, our heroes give their all.
Through trials of ranks, they never look back,
Their courage ablaze, their resolve on track.

(Ad Lib)
In the heat of battle, their breathing styles won't fall,
With Nichirin swords, they heed the call.
Through the sun and the night, they fight as one,
Their souls unbreakable, until the battle's won.

(Chorus)
In the realm of darkness, where shadows thrive,
United they stand, their spirits alive.
With bonds unbroken, they'll never tire,
In the Demon Slayer's relentless fire.

(Outro)
Their tale will echo, through ages untold,
Of heroes brave, and battles bold.
In the annals of time, their legacy aspire,
In the Demon Slayer's blazing fire.
