Hello~

I've brought along new equipment as a souvenir.

Ursula? When did you get here!?

As usual, Karlsland is making strange weaponry.

And like this, it becomes the kitty corner shot Here the words "neko" and "ko-na-" (corner) are conjoined to make "neko-na-" which is just a pun playing off the kitty corner shot rifle

As such, this can be used as a corner shot.

.... I heard you'd split up.

Ah, the Vorsatz curved-shot gun barrel. "Vorsatz" is actually German for (in this context) an attachment or extension on an object. However, because she specifically uses the German word instead of the Japanese equivalent, I'm not sure if it's meant to be just the term, a pseudo-brand name, or what.
