[Starlight Breathing]! He transmigrates into Demon Slayer and awakens an invincible System on the night his family is slaughtered. After lying low for twelve years, he invents his own Breathing Style and makes the Twelve Kizuki his targets. He saves Kanae, changes the original story’s tragedy, and points his blade at Muzan: “I’m taking your life.” In this life, I’ll burn away the night with my mortal body and protect the last spark of light in the world.
