Kaname comes in and tries to stop him just like the doctor's daughter does. I won't do that whole "vampire" concept but, I don't know. and yes, Pyrite I am trying to write this WITHOUT ripping it off.
Yes, Weltall Elite, There were 3 endings according to GameFAQS.
1. Kill Your father who transformed into a hideous creature with a gun (Good)
2. Follow your father's orders and give yourself up for his life. (Bad)
3. You run of time and are trapped in his world (Also Bad).
EDIT: Didn't he shoot the bystanders with a gun and then take hostages?
