[While Megumin can appreciate the fact that he's amused by her crab slaughter, she's finally got her fire going and is roasting this sucker while the other crabs decide what they should do. She just shrugs as she continues to cook the once singing and lively little crab.]

I'm not really the army joining kind of girl. I may occasionally obliterate entire armies, or help out in a war effort, buuuuut I'm an adventurer with some rather grand ambitions already.

[She grabs another crab that hadn't decided to flee fast enough, and has it held in such a way so that its pincers can't hurt her. She's clearly practiced hunting pinching marine life on many occasions, and now the other singing animals are starting to scatter in a panic.]

Still, you're kind of interesting. If you want some crab you're welcome to join me. You might want to catch some before they get away if you're hoping for more than one though.
