Man, mangaka really love their effeminate MCs.
I wondered if it was just the scanlator's doing when he went "KYAA" when startled by that severed head's landing, but then he went "AWAWAWA" in the next panel--all next to Sylphy's complete composure (well, she was more like a mountain gearing up to become a volcano).
After that, the "dragon" has its breath attack completely no-sold by Sylphy's casual show of power, and he's still wigging out like she's in serious danger--which is the kind of thing women do to men (whether out of genuine concern or disdain). No thinking, just wild feeling. I get it, he's a mob, he's a regular Yamada Taro, he's nothing of note; does the author have to go this far, though? Or maybe he does, since Mr. Yamada is what the average JP reader's supposed to relate with.
At least Sylphy's gorgeous and adorable--and pretty cool.
