Chapter 2

Someone Unknown (らぬか) is the second chapter of Koyoharu Gotōge's Kimetsu no Yaiba.

Summary
Following Tomioka Giyuu's advice, Tanjirou buys a bamboo basket and covers it with a cloth so that he will be able to travel with Nezuko under the sun. The basket proves to be too small to fit the teenage Nezuko, however, Tanjirou persuades her to use her Demon blood to turn her body smaller so as to fit into the basket. After asking for directions, Tanjirou heads off to Narrow Mist Mountain with the basket containing Nezuko on his back.

As night falls, they both find a small temple hut in the woods and decided to seek shelter for the night. As they neared the hut, Tanjirou smelled blood. Thinking that there might be some people hurt from travelling the mountains, Tanjirou rushed into the hut to find a Demon feasting upon three dead travellers who were also taking refuge for the night. The Demon shot them a glance and warned them that this was his feasting grounds.

Upon seeing the bloodied bodies, Nezuko starts to salivate. On the other hand, Tanjirou is in a state of shock as this is the first time he is seeing a human-eating Demon.

It was then that the Demon realizes that Tanjirou is human and subsequently goes for the kill. Tanjirou uses his axe to slash the Demon by the neck, but the Demon's wound had already started to heal. The Demon proceeds to strangle Tanjirou to the ground with his agility and strength, but Nezuko kicks the Demon's head clean off from his neck. Even so, Tanjirou laments that he did not intend to kill the demon but he had to because it was a demon.

Although its head was removed, the Demon's body continued to attack Tanjirou. This caused Nezuko to give the headless body another kick. The Demon's head yelled at Tanjirou, asking why would a Demon and human travel together, then commanded its body to start attacking Nezuko.

While Nezuko was occupied, the Demon grew a pair of arms from its head and charged at Tanjirou. Tanjirou headbutted him (the Demon even acknowledged that Tanjirou's head was tough) and pinned the head onto a nearby tree with his axe handle. As the headless body continued to kick Nezuko, Tanjirou tackled the body, not knowing that they were beside a cliff. Thankfully, Nezuko grabbed onto Tanjirou as the headless body fell splat onto the ground below. Although it cause the Demon great pain, it did not kill the Demon.

After the siblings return to the Demon's head by the tree, Tanjirou brings out a small knife, intending to end the Demon's life. Even so, he hesitates to kill it.

All of a sudden, a person wearing a strange mask approaches him from behind and tells Tanjirou that the knife that he is holding would not be able to kill the Demon.
