This series was supposed to be a six parter and it was indeed but I don't understand it
Between 3 and 4 some other guy appears (long red hair) and becomes Jutto's rival but they didn't show the backstory/how they fought.
What happens to the guy with long white hair?
The Demon Queen and Demon King are still alive and only that mannequin is defeated
P.S. Is there any SHORT manga/cartoon I can watch about martial arts OR a team of superheroes. I recall X Men Evolution but I stopped after season 2 and don't remember how long it really was
