Luckily for Sora, Jin's attention was off him for now, since the major was now too busy with that blocky freak. Jin wasn't going to let something like that go by unscathed. Hitting him without apologizing, not referring to him as Major Kisaragi, and now he's being snarky?

So Jin's solution to that is obviously to force this trash to learn some manners when speaking to his superiors. He'll raise his hand, and would proceed to aim a slap at the face of the blocky man.

"You need to learn some discipline, you worthless trash!"
