Understanding the problem with Fragments

"So... care to explain why there are two hotties tied up like it's a BDSM photoshoot?" Katharina asked, crossing her arms as she stared at the scene in the luxurious living room. There, in the background, were Iridia and Zex—both incredibly sexy—bound in a highly suspicious manner, with knots that seemed more decorative and fetishistic than functional.

Vergil, lounging in an armchair as if he owned the chaos (which he did), simply pointed at Novah. "It's her fault."

"Eh?! You asked me to do it!" Novah exclaimed indignantly, her face turning bright red in seconds. She flailed her arms in protest, though her defense wasn't helping her case much.

"Ah, of course... the perverted maid," Ada sighed, adjusting her glasses as she cast an exasperated look at Novah.

"P-perverted?! I'm not perverted!!!" Novah roared, her voice hitting a higher pitch as her embarrassment deepened.
