『Moon Hashira』
Michikatsu Tsugikuni, the elder twin son of the Tsugikuni family during the Sengoku period, was the elder brother of Yoriichi Tsugikuni, the originator of Sun Breathing. Because he could never grasp his younger brother's breathing technique, whose divine essence was like the sun itself, he carved out another path amid obsession and solitude, single-handedly tempering a "Moon Breathing" that matches its brilliance. His swordsmanship pours down like a cold moon, bitingly frigid to the bone, its techniques unfolding with the vastness of moonlight shining over all, uniting the beauty of lofty solitude with devastating, overwhelming power. Through this path, he ultimately became the uniquely distinguished "Moon Hashira" of the Demon Slayer Corps.
Unable to touch the sun in this lifetime, I became the coldest moon in the night.
