Demon Slayer: Kimetsu No Yaiba: the Unspeakable Dawn

He is known as the "Sun" of the Demon Slayer Corps. Mingjing Yongji, the pillar of light, has a smile as warm as the morning sun and a bright and unique sun blade. He is a close friend recognized by Purgatory Anjuro, a gentle senior whom Tanjiro's three little ones admire, and a fellow traveler with Buddha nature in the eyes of the mourning island. He forgot about his past and devoted himself to killing ghosts and guarding every smiling face in front of him. Until the whistle of the Infinite Train blows, and the whisper of an old friend awakens the sleeping memory - he once voluntarily fell for love, and was an evil ghost who had a confrontation with Jiguo Yuanyi a hundred years ago. When the truth tears apart the pretense of calm, when the curse of Wu Ke tightens its neck. He chose to wear the mask of "betrayer" and crush the past friendship into a sharp blade that stabbed his companions. "Mr. Eiji... It's a lie!" Tanjiro cried from behind, "I smell it! It's sadness thicker than blood!" He smiled and walked towards the determined end. Behind him were the blades of his former comrades, and in front of him was endless darkness. If the light is born to be a lie, he is willing to sacrifice himself to burn this long night. This novel and its characters are purely fictitious.
