Demon Slayer Manga Chapter 170

The battle against Kokushibo becomes even more dangerous as Muichiro frees himself from the pillar despite his terrible injuries. He knows he may not survive the fight, but he refuses to waste the chance to help the others. Genya asks him to give him a piece of Kokushibo’s hair so he can use his unusual ability to gain strength and continue fighting beside his brother.

In Demon Slayer Manga Chapter 170, Kokushibo reveals the deadly price of awakening the Demon Slayer Mark, claiming that marked swordsmen will not live past the age of twenty-five. Gyomei refuses to be shaken by the warning and rejects Kokushibo’s belief that becoming a demon is the only way to preserve strength. As Sanemi awakens his own mark, he joins Gyomei in battle, and the two Hashira begin working together against Upper Rank One.
