Wha- I just dismantled all your arguments and now you say "and now you give up" lool.

Killer Queen will never touch king Crimson, because the latter is too fast and epitaph exists.

King Crimson with a simple hit oneshot Kira.

Their speed is practically the same

King Crimson scale to star Platinum according to JoJo a go go.

Its speed and power are "first class"

Killer Queen scales to Crazy Diamond, which in turn scales to Star Platinum

Why do you use the word “blitz” so much? Is that even what blitz means?

Blitz = overtaken in speed.

Star Platinum "blitz" killer Queen means that star platinum has overwhelmed and surpassed the speed of killer Queen.

Even if King Crimson punches through Kira’s stomach he can just touch the fist and they’ll both die

He can't, because King Crimson moves too fast than killer Queen.

If you think about it, why didn't he do it with Crazy diamond and star Platinum ? Simply because they were too fast.
