Demon Slayer Chapter 104

Demon Slayer Chapter 104, titled "Kotetsu," plunges Tanjiro Kamado into a grueling, relentless training regimen with the Yoriichi Type Zero mechanical doll, guided by the demanding yet insightful Kotetsu. The chapter opens with Kotetsu comically suggesting insults Tanjiro could use against Muichiro once he surpasses him, but Tanjiro, ever humble, dismisses the thought, focusing instead on his own growth. He begins his intense training with Yoriichi Type Zero under Kotetsu's meticulous supervision. Kotetsu, fueled by newfound motivation and his keen analytical skills, relentlessly critiques Tanjiro's every movement, demanding perfection. He declares that Tanjiro will receive no food until he achieves the desired level of proficiency, pushing the young Demon Slayer to his absolute limits in the captivating narrative of the Demon Slayer manga.

Kotetsu then demonstrates an intricate method of adjusting the doll's movements by twisting its fingers, allowing it to adapt to Tanjiro's weaknesses, comparing the process to solving a complex wooden puzzle box. With the doll readjusted, Tanjiro endures brutal training sessions, deprived of food, water, and sleep, all under Kotetsu's unyielding direction. This extreme regimen is a testament to Kotetsu's unwavering belief in Tanjiro's potential, coupled with his youthful ignorance of human limitations. Just as Tanjiro approaches the brink of collapse, experiencing a sensation akin to crossing the Sanzu River, he develops a remarkable new ability: he can now smell the incoming movements of the doll. This breakthrough allows him to land a decisive hit, earning him his first meal. With this enhanced foresight, Tanjiro continues his rigorous training, steadily improving his stamina and predictive abilities, showcasing his remarkable adaptability and growth as a Demon Slayer.

In the midst of a sparring session with the doll, Tanjiro's newly refined abilities create an opening for a decapitating blow. However, he hesitates mid-swing, worried about further damaging the priceless mechanical doll. Kotetsu, sensing his apprehension, passionately yells at him to strike, reassuring him that he can fix it. Internally, the young boy silently pleads for Tanjiro to remain unwavering, hoping that one day, he will surpass everyone else in strength. With Kotetsu's fierce encouragement, Tanjiro overcomes his hesitation and successfully lands a powerful blow to the doll's neck, inadvertently breaking his training sword in the process. He apologizes to Kotetsu for the ruined blade, but after Kotetsu's sudden exclamation, Tanjiro turns to see a sword's hilt mysteriously emerging from the doll's body where its head once was. This dramatic reveal in Demon Slayer Chapter 104 hints at a hidden treasure, promising a significant upgrade for Tanjiro and adding a new layer of intrigue to the unfolding Swordsmith Village Arc in the thrilling world of the Demon Slayer manga.
