Demon Slayer Manga Chapter 186

Tanjiro finds himself in a strange house that looks familiar, but he soon realizes that he is witnessing memories from the distant past. Under a tree, he meets Yoriichi Tsugikuni and begins seeing the life of the man who created the first Breathing technique. Yoriichi remembers his childhood, his mother, and the brother who once cared deeply for him.

In Demon Slayer Manga Chapter 186, Yoriichi’s memories become even more heartbreaking as he tells the story of meeting Uta and building a peaceful life with her. That happiness ends when a demon kills Uta and their unborn child while Yoriichi is away. After losing his family, he becomes a Demon Slayer and teaches others the breathing techniques that eventually lead to the five major styles. His memories finally lead toward his first encounter with Muzan, the demon he was born to defeat.
