Chapter 51

The Nichirin Sword Returns (る) is the fifty-first chapter of Koyoharu Gotōge's Kimetsu no Yaiba.

Summary
The chapter begins with Zenitsu and Inosuke staggering as they try to learn Full Breath techniques in order to advance with Tanjirou's skill. Despite numerous attempts, the two boys were unable to grasp the concept of the technique and struggled to master. During one of Tanjirou's lessosn, Shinbou interrupts to provide words of encouragement and guidance to both Inosuke and Zenitsu. However they react in different manors with Inosuke reacting in a hostile manor, even threatening to "rip [Shinobu's] breasts off" whereas Zenitsu reacts bashfully at reddens when she grabs his hand.
