How about a manga about righteous revenge against those who have wronged the main character?

Anything is fine other than Yaoi or Yuri.

if you have not read it Kuroshitsuji is a popular one about revenge and it is very very good. the MC is the son of an earl in england when his family gets killed and he gets kidnapped to become part of a ritual to summon a demon. but the demon sees him as the one that summoned him and gives him the option to make a deal with him. the MC accepts the deal with the demon and the rest of the manga is about him getting revenge on the people that did that to him and his family.

Chang Ge Xing is also a very good one, the MC a princess of han with her father being the crown prince, but there is a coup d'etat and her uncle orders everyone in her family to be killed and she is the only one that escapes. after that she pretends to be a boy to gather an army to take revenge on her uncle.

Like educational manga? take a look at Ed U. Manga's list of manga here

Berserk Definitely the best series for revenge. Please don't drop it because of its lackluster start & bad artwork... the story & artwork evolves after first 2-3 volumes There is a lot of gore though (and one rape scene). Highly recommended

Übel Blatt Personally I'm not a fan of this series but it's popular and fits your requirements
