if any of u have read mirai nikki im pretty much looking for a manga about what happened with Marco and Ai before they became diary users

when Marco and Ai were in high school, Ai got raped and assualted by three high school boys. Marco finds them and goes on a ramping outrage and even kills one of the high school boys.

so Im looking for something similar to that where the main female lead gets hurt and her lover/boyfriend goes out on a rampage when he find out what has happened to his lover. im not looking for anything like in usual shoujo mangas where the male lead "cooly" saves the female lead like they always do. i want full out RAGE when something happens to his love. Like Marco from Mirai nikki

Once you get past the violence and the gore Wolf Guy - Ookami no Monshou

Man is more ape than many of the apes.

Not sure if it all fits but:
100% Perfect Girl - some parts since the male lead is a possessive lover
Flowers of Evil
Hot-Blooded Woman - sorta

Well there's "The breaker" and it's sequel "The breaker new waves". Not exactly all are female lead and male lead but still it includes important characters that fulfill your requirements.
