Demon Slayer: From the Start, I Master Sun Breathing and Crush the Hashira

After transmigrating into the world of Demon Slayer, Lin Ye awakens the Blazing Sun Demon-Slaying System from the start. With mastered Sun Breathing and a permanent mark, he becomes invincible. Starting before the night the Kamado Family is wiped out, he defies fate, saves Nezuko, protects Rengoku, kills the Upper Ranks, and shields all the Hashira. At last, just before dawn, he burns Muzan to ashes with a single slash, giving every unfulfilled wish a happy ending.
