Infrared isn't exactly something that one can explain. You don't just begin seeing things in shades of red depending on how hot or cold they are, that was just how human's processed the data when looking at things through infrared sensors. No, an insect like species like Suparna didn't even "see" infrared at all. It was an sense entirely separate from the usual five humans used to experience the world, you didn't see, smell, touch, hear, or taste heat. You simply felt it. And in this moment, Rose could feel an immense heat building up in this creature's maw, and she could feel that it was going to come at her in a matter of moments. She could feel the path it would take, almost like she was seeing just a second into the future to see where it was aiming. Or maybe that was just the instincts of the finely trained warrior who was currently occupying her. Or was it the other way around?
Clair's knife clips the creature's jaw and it falters, the energy is just slightly destabilized, slightly weaker than it should have been. A sphere of purple luster shoots directly at the pirate paladin, but somehow Rose just knows that she'll be fine. This shield has stood up to far worse in the past, so something as simple as this was like throwing a tennis ball at a brick wall. Rose's arm swings out in the direction of the projectile and she can feel her muscle memory screaming at her to bat it away into the wall, but something else is telling her otherwise. The energy is just slightly destabilized, slightly weaker. This opens up the opportunity for more damage. She adjusts her angle of impact accordingly, the ball of dark light slams into the shield with the force of a sledgehammer yet Rose's arm doesn't even tremble. It only continues forwards and out, the energy ball distends and warps for a brief moment before rocketing right back at this dumb snake's face to send it crashing through the wall.
"Hey! Who the hell said you could attack me huh!? Get out of here before I go grab Victoire and have her make you into a steak!" Wait what? Rose touches her lips with her free hand as she wonders just what the hell she's talking about, for a moment she's totally off guard as her shield lowers a tad out of sheer confusion. She didn't even notice Thomas charging in to join the fray, a welcome addition to be sure but... who was just talking right now?
Ami rolled her eyes at Riku's question, everyone knew who Sherlock Holmes was. And while she didn't read any of those long ass boring books, she would always skip to the end to find out who the killer was, she could definitely say she enjoyed that one Sherlock Holmes movie where his answer to every situation was to just beat the shit out of everyone. Hehe. Discombobulate. "Yeaaaaaaaah, I don't really feel like answering your stupid questions. You give your alibi first, how about that." Riku's first mistake was assuming she was dealing with a rational and polite human being who would be more than happy to cooperate in an attempt to find the true thief. Ami was none of these things, she was just here to kill her way up this Tower and get stronger.
Now Kanbaru-chan, she definitely had the right idea of things. "Yep, I like that plan." A beastly smirk adorned her features as she cracked her knuckles and stared right at Riku, before vanishing from sight nearly in sync with Kanbaru. The two former magical girls knew exactly how the other thought after fighting together for so long, even if they were never a part of an official duo. A moment later she would reappear behind Riku as she backed away from Kanbaru defensively, fist cocked back and wreathed in dark flames. "Yeah yeah, tell it to the judge!" Her tone communicated boredom, but the look on her face was anything but. It was with great joy that Ami donkey punched Riku directly in the back of the head, a smooth knockout if it landed cleanly. Her first mistake was assuming Rose was rational and wanted to talk things out. Her second was assuming Kanbaru would be the same. Her last was taking her eyes off of the Demon Knight for even a second.
