Demon Slayer Manga Chapter 133

Jealousy, apparently, is an excellent teaching tool. Obanai Iguro’s stage in Demon Slayer Chapter 133 is a maze of wooden posts with bound trainees hanging between them, and the Serpent Hashira strikes at Tanjiro through the obstacles, correcting every flaw in his sword form with stinging precision and open irritation.

Why the extra harshness? Word reached Obanai that Tanjiro spent cheerful days training under Mitsuri, the woman he quietly adores. Tanjiro, oblivious to the reason, simply improves under the pressure, learning to swing accurately through impossibly tight spaces. He leaves with sharper skills and a sincere thank you that Obanai absolutely did not want.
