Devastated by the slaughter of his family and his sister turning into a demon, Tanjiro becomes a Demon Slayer to find answers. With each fight he becomes more proficient with his blade and slowly begins to master his breathing technique. But you shouldn't face demons alone. Luckily, Tanjiro has his sister with him, and joining them are fellow Demon Slayers, the fearful Zenitsu and the brash Inosuke.
