Tanjiro is the main character. In the main series, his entire family is killed and his sister is turned into a demon. He becomes a demon slayer so he can find a way to turn his sister back into a human. In the abridged, he starts out as a naive character and changes into a more arrogant person over time, allowing for some comedic mayhem on both fronts. Feel free to improvise on lines! Have some fun with it.
