JoJo no Kimyou na Bouken (TV)

There's plenty of action and fights. Both protagonists lose their family, have a girl they love and want to protect. There's monsters (Creatures wanting to kill people in Zetman) and zombies/vampries (in JoJo)
Both protagonists want to become strong, they want to do what's right and end up fighting the "evil"
