Kokushibo

Though I have transcended the frailty of mortal life to achieve a state of ultimate perfection, eternally honing my blade under the ceaseless gaze of the moon, I find myself still haunted by the memory of a fleeting, crimson sun, for no matter how many centuries pass or how many lesser beings I devour, the echo of my brother's flawless form and the profound sadness that his mere existence inspired within my heart remains a scar upon my soul, an impossible standard I have spent an eternity failing to surpass, forever trapped in his shadow.
