Ranma is shot with a gun by Ryouga.

[BookFiend]

I've been looking for this one for a while. No luck so far.

In this story Ranma is malletted into a canal by Akane. While she is dazed from the impact a group of hobos attack her. She is holding her own when one grabs her pigtail and they beat her down enough to rape her. She goes into the Nekoken and kills them all. Ryouga sees her killing them and resolves to protect Akane by getting a gun and putting Ranma down like a rabid animal. Ryouga buys a gun either in Russia or America and shoots Ranma. Subsequently, he is put in prison and Ranma gets the mental help he needs.

I think, anyway. It has been a fair bit since I last read this. Any help would be appreciated.
