Quotes: Violently Protective Girlfriend

I got your back until I die
I don't care if you don't want me sticking by
I'll keep ten feet behind just to walk you home
And I'm gonna protect you till I die
I won't let nobody hurt you again
I'm gonna flop note  your next girlfriend if she breaks your heart
Tijuana Sweetheart, "Seven"

"No one beats up on my man but me!"
Lee Kanker, Ed, Edd n Eddy

"I'm going to find the thing that's doing this to you and break its heart."
Red, Transistor

"You were dead the second you touched Julian Keller."
X23 to Lady Deathstryke

Of course, in the middle of the open war against Asuka's presence, everyone in the room failed to notice Shinji's change of mood. With every insult directed towards Asuka, he felt rage unlike any other build inside him like a deadly current threatening to consume him completely. He could stand anything people directed his way, as long as it was him who was offended. No-one, NO ONE had the right to insult Asuka, they had no idea what she had been through, what she had suffered. Such a thing would not stand.
Scar Tissue, chapter 8

Kaworu flinched from the exquisite pain as Asuka's fist rocketed into his stomach. It took merely a second until his smile returned while the redhead used the chance to escape his close proximity.
"If you really need to know: Yes, I am afraid!" she admitted yelling. "I won't let him be hurt, not by you or anyone else."
Asuka, The Second Try, chapter 11

"Misato-san, the mother I missed during my childhood, for all her terribly human flaws. Rei-san, the sister I never had, as much as she can annoy me at times. And you, the girl who I never knew I wanted to steal my heart. If anything ill were to ever happen to any of you, it would be bad," Shinji says with a smile.
"How bad?" Asuka asks.
"Ah, so its more pillow talk you want now, is it? Well, first I would find those responsible and I would begin by… oh, let's say cutting their Achilles tendons so they can't get away. Then would begin the slow, methodical removal of limbs, inch by inch, each new wound being cauterized to avoid death by blood loss. By the end they would be skinless heads attached to torsos, eyes gouged out, noses cut off, tongues yanked free of mouths, lips sewn shut with rusty ten gauge wire, and tubes inserted to keep them alive and in pain. I would then probably conquer the world, or at least a large chunk of it, so as to build a suitably grand tribute to the loss, probably a pyramid to embarrass the ones in Egypt, only made out of the bodies of my enemies coated in resin to prevent decay and give better structural stability. This of course would be occurring while I try everything to undo the damage," Shinji describes vividly.
Shivering in a mix of fear and pleasure, Asuka says, "Sweet talker."
Thousand Shinji, chapter 13
