I am looking for serious manga with women that abuse their lovers/friends or siblings. I don't mean playfully punching someone or slapping them because they cheated or whatever. I am talking full out abuse. Mental and Sexual abusive is okay as well. All genres are ok, but the abusive woman needs to have a central/important part in the manga.

Examples;
Fruits Basket

Akito physically and mentally abuses just about everyone in the entire series. Including her lovers.

Transfigured Night

A man that was sexually abused by his older sister and still suffers from it.

I hope you can help. ^_^

Edit for clarification; I DONT want abusive mothers/stepmothers or other parental figures. Women that abuse their friends/lovers or siblings only.

Hoozuki-san Chi no Aneki?

Seigi no Mikata I don't know if this fits exactly. The older sister is a selfish bully, except her malicious actions have beneficial outcomes.

Feed your head.

Miya-sama from Oniisama e is like this to her

sister.

Kanojotachi no X-Day the male lead get abused by his mother

Kare Kano
Komatta Toki ni wa Hoshi ni Kike! - if you don't mind shounen ai tints.

I think Life has them.

Isn't there something along those lines in Loveless? Though I haven't read it, I'm sure the main character was abused by his mother.
Maybe Sayounara, Utsukushii Hito will fit too.

Thanks a lot guys. ^_^
Btw. I don't want abusive mothers. That's why I spesified by saying I wanted women that abuse their lovers/friends or siblings. I tink I made it pretty clear. ;P
