Wow, when I saw Youmu in the thumbnail, I thought we were gonna get shy bashful Youmu, but instead it seems we have Youmu the badass defender of Hakugyoukuro.

And of her own honor, too. I can't read her response, but from the peeved expression, drawn sword, and the dismayed なんでや from the guy, it's as if she's threatening to cut it off.

Wonder if we're gonna get Yuyuko next.
Dude: Let me do you.
Yuyuko: Sure, but treat me to dinner first!
Dude: (What do I do? I'm gonna go bankrupt...)

Oh, masara, you so punny...

Youmu will fuck you up, unseen sex addict.

just to explain the pun, "let me do you" and "get fucked up", or rather "get killed" are pronounced exactly the same way, hence youmu's answer.

Ah, too bad he ran into canon Youmu...

Whoa Whoa Whoa!!!Slow down there, i want a duel but not a sword duel.

Sword duel...

It's not like that he doesn't have one.
Even though it is more on the soft side...

Alternatively, if you wanted to keep consistency with the translations of the other strips' "Let me do you", you could have Youmu's line as "You want me to... do you in?".

though that would ruin the last bubble

Over her head. Completely.

"Let me do you"
"You want me to... do you in?".
"Very well, I will do you in."
"Do what?"

This probably should have been the last one.
