Demon Slayer at the Beginning, Kill Ghosts to Unlock Pirate Skills

This is a world that combines Demon Slayer, Inuyasha, Slippery's grandson, and Tokyo Ghoul. Leng Ren thought he was coming to the Demon Slayer World at first, until one day he met a monster and heard the names of Sesshomaru and Inuyasha. He understood that this was not the Demon Slayer World. Later, he passed through the "Bone-eating Well" and came to modern times, where he met a white-haired man named Kaneki Ken and a half-demon named Nura Rikuo...
