Biske swept Gon's unconscious body towards Killua.
Would the boy ever learn to take things in stages? Most likely not, the poor headstrong fool. However, that wasn't the problem now. Gon was out, Killua was fading fast, and Hisoka was never an individual Biske would feel comfortable relying on. Furthermore, a sheer cliff-face blocked their only exit as the enemy geared up for another devastating blow.
It was looking like she would have to do that.

Hisoka was not amused. Not amused at all. What should have been an exhilarating display of his future opponents' growth was becoming a real drag. Soon, he would have to take things seriously, or risk losing the most promising rival he'd had in some time.
Preparing to employ bungee-gum, Hisoka saw something terrible, something truly UNATURAL, out of the corner of his eye. From the direction of the small blonde annoyance, bits of pink fabric started flying through the air.
From this maelstrom of tea-shop satin and ruffles, emerge a horror. Muscles. Chin. Towering height. Eyes of a demon. All topped with a small, blond, curling, pony-tail (the only testament to whom this grotesque figure must be).

Biske quickly subdued the enemy force. Disgusted with being forced to take this kind of measure, she turned to berate her (temporary) allies.
Killua and Gon were nowhere to be found; one couldn't say the boy was dumb. Biske returned to her masked form and headed out to find the two boys. There was no need to be concerned that the clown would tell anyone.

In the remnants of the field that was once their battle ground remained only a quivering mess. Hisoka stared at the sky, praying to a god he didn't believe in, that such a monster would never again be sent to him./p
