As the ninja explained himself, and stated that he didn't intend to kill the thugs, Zehst finally seemed to fully relax again. True, the explosions hadn't been super huge...and they seemed to be mostly light and show, if the force behind them was only enough to knock the bad guys out. 

"Well...if my parents didn't make it, and you're careful about how you use it...then I guess that's your freedom, huh?" he said, before nodding to himself. "Sorry about hitting you, then. I just...have a thing about weapons of mass destruction." He rubbed the back of his neck and smiled bashfully. "I'm Zehst, Zehst Messerschmitt, by the way. I ate the Roke-Roke Fruit, so now I'm a Rocket Man!" A small set of turbines opened up in the hollows of his ears, spitting flame to emphasize his point, before with a "shwoop" they withdrew. 

The old man they had inadvertently helped offered to feed them, at which Zehst's stomach rumbled like a B52 jet. He nodded heartily to the geezer, but then the cool giant mantis said, in a surprisingly girly voice, that she had to change first. The mantis spun and shrank, mandibles and arm-blades disappearing as chitin became skin, and in its place soon stood a lovely young lady, who introduced herself by name. Zehst pointed, his jaw dropping and eyes bugging out.

"Ah, cool-outfit-guy! The giant mantis can turn into a pretty girl! How're we supposed to catch her now!? I'm no good with girls!" he said, his voice rising an octave higher. Because he'd been cooped up in his mansion with only his parents and his tutors and a babysitter for company, he'd never really interacted much with kids his own age. Now he was older, certainly, but he still hadn't gained any of the experience needed for proper social interaction. Especially not with girls, who were destined to be an enigma to even the most experienced of fellows.
