Sakonji Urokodaki

Urokodaki Sakonji is a former Demon Slayer.

Final Selection Arc
Having received a letter from Tomioka Giyuu requesting that he train Kamado Tanjirou, which also explained the boy and his sister's circumstances, Sakonji set forth from his home to find the two. Upon finding them, he stops Tanjirou from attempting to kill a Demon with his knife, stating that the boy will be unable to kill the creature with such a dull weapon. Admonishing the youth for his question of how to properly defeat the beast, the elder watches as Tanjirou struggles to come up with a way to dispatch the creature. Sniffing the youth, Sakonji determines that he is no good, as he still has the scent of kindness even when confronted by vile demons.

While Tanjirou is still struggling to kill the demon, Sakonji buries the victims of the creature, afterwards kneeling by their graves with his hands together in prayer. He then introduces himself to the youth, asking if he is the one Giyuu spoke of in his letter. Getting an affirmation to his inquiry, Sakonji goes on to ask the boy what he will do if his sister decides to feast on a human, slapping him when he hesitates to answer. He admonishes the youth on his slowness to answer, stating that he lacks determination, and stresses that he must not allow his sister to harm another human under any circumstance. Getting an answer of conviction from Tanjirou, the elder agrees to test the boy to see if he is worthy of becoming a Demon Slayer, telling him to bring his sister and follow him.

Sakonji then swiftly makes for his home, with Tanjirou struggling to keep up with his pace. Arriving at their destination, the elder tells the exhausted youth that the test begins now, instructing him to hike up the mountain. He travels with the boy part way up the mountain, telling him that he must make his way back to his home before dawn. He then vanishes into the heavy fog surrounding them. Later, having made his way back down the mountain, Sakonji drapes a blanket over Nezuko, before noticing a noise at his door. A heavily exhausted and injured Tanjirou opens the door, prompting the elder to recognize his abilities, and thus his passing of the test.
