He tries exploiting his control in a different way.

As Megumin got up, Kazuma snapped his fingers again. "Megumin, you can specialize in the explosion magic all you like, but you lack versatility. When you get more skill points, and more equipment, and higher levels, I want you to rectify that," he tried out. "Explosion can be your best spell, but you can stand to work on having some mid level magics, or even work on using Explosion more than once per fight."

Megumin actually seemed to shiver a little bit, twitching as her mind took the order, before stilling and nodding again. '...whoa, she actually put up a lot of resistance to that. She really is an explosion nut...' Kazuma thought.

"Ugh... My head hurts... And my nose is bleeding for some reason," she then stated, and sure enough, there was a trickle of blood running down from it.

'Okay, that's just ridiculous,' Kazuma sweat dropped, before Megumin blasted away at the cliff.

"Well, I see you found a different spot to blow up!" Darkness said cheerfully as Kazuma walked back with Megumin on his back.

"I wouldn't be able to deal with Megumin's complaining if I didn't," Kazuma replied.

Darkness then suddenly yelped as Aqua came up behind her and groped her breasts from behind. "We still need to figure out a way to make money though!" Aqua whined, acting as if she wasn't doing what she was doing, which Kazuma knew was her filling her new perverted act quota.

"You mean YOU need to figure out a way to make more money. At least today was your last shift," he teased Aqua, who pouted and whined. "Hopefully the Dullahan will be gone soon, if not though... Well, we'll think of something I'm sure."
