Iji Kataiser
One of few remaining humans after an alien invasion(Nearly 95% death rate). She doesn't take the knowledge of the near genocide of Earth very well but she has trouble actually killing any of them. You can play through the entire game without killing a single foe and she will become more confident in her belief that there doesn't need to be more bloodshed. If you kill one of the aliens intentionally or accidentally she'll even apologize for doing it for the first few times. Or you can have her take revenge on the invaders. Eventually she'll be reveling in destroying every last Tasen she comes across if you take it far enough yelling out "Die!" as she kills any in her way.
Someone in her position would probably have a fragile mental state, and it does show. She hallucinates finding bows that her younger sister used to wear. She flat out breaks down after learning how badly earth's been hit. There's a certain point in the game where depending on how you handle a situation she can completely snap and start talking to people that aren't there.(The last boss notices this and takes pity on you if you reach him in that state)
