Demon Slayer Manga Chapter 177

Kokushibo looks back on the childhood he shared with his younger twin brother, Yoriichi. From the beginning, their lives were completely different. Yoriichi was treated as an unwanted child because of the mark on his forehead, while Michikatsu believed he was the talented brother destined to become a samurai. That belief changes when he witnesses Yoriichi’s incredible swordsmanship at only seven years old.

In Demon Slayer Chapter 177, Michikatsu slowly realizes that Yoriichi can see inside the human body and possesses a natural ability he could never match through training alone. Even more painful is discovering that Yoriichi had always understood their mother’s illness and stayed close to her to support her. What Michikatsu once saw as weakness suddenly becomes another reason to envy his brother, deepening the jealousy that will eventually shape his entire life.
