I want to rip her mecha apart.
Then pull her out of the cockpit. Then I exit my own, and engage in fisticuffs battle.
As we clash with each other again and again, tearing and kicking the life out of each other, she'll smile, and so will I. And, as I deliver the final blow by a slight advantage, she will thank me for such an epic battle, and will ask if I can be her friend. How can I deny a dying girl of such a request?
Then I'd take her battered and broken body to a graveyard, and give her a hero's funeral.
