Tanjiro trains rigorously on the mountainside with seasoned Demon Slayer Sakonji Urokodaki only to meet his most challenging task a year later: splitting the world's strongest boulder in two using nothing but his sword.
It's Tanjiro's first and Final Selection, and he's being stalked by a morphed demon whose scent reeks of its previous victims. This isn't the kind of class reunion Tanjiro was expecting.
The Final Selection leaves only four swordsmen standing, who move on to the next stage to becoming Demon Slayers by crafting their own Nichirin Swords.
Now clad in the official Demon Slayer uniform and with his very own Nichirin Sword, Tanjiro heads into town on his first assignment with Nezuko in tow to locate the town's missing girls.
And then there were three. Tanjiro, backed into a corner, is saved by Nezuko and follows the demons to their swamp.
Small-town Tanjiro is thrown into the bustling city life as his next assignment takes him to Asakusa, Tokyo where he picks up a scent.
The two demons named Tamayo and Yushiro, who came to Tanjiro's rescue, reveal a possible cure to turn Nezuko back into a human.
Tanjirou's arsenal of techniques barely holds Yahaba's final Blood Demon Art at bay. Think German Expressionism, only demonic.
