Toy box: Killua
With ivory skin and seemingly delicate limbs, Killua was the perfect porcelain doll. Despite years of harsh training under his family, Killua's skin looked smooth and supple. Such an untarnished body he had. It called to Hisoka to grab it, touch it, and mar it with hickeys and bruises. He'd finger paint his doll's skin with sickly blue and purple prints as he caressed it.
In the distance, his doll rubbed hands dirty with melted chocolate against brown shorts.
Such a dirty boy, but don't worry. I'll make sure you learn your lesson.
A familiar bloodlust was seeping over the area. Swirling against his body almost playfully, the offensive nen carried a clear message. I. Found. You. The source stayed out of sight and out of Killua's En range, but too close for comfort.
Sugar, fear, and caffeine left him tapping his foot impatiently as he waited for the waitress to return. Tossing down a wad of Jennys far too large for the just a chocolate cake slice and some cheap coffee he fought down a shiver. He needed to get out of the cafe and get back to Gon. He'd take a different route back to their hotel and double back a few times just to be careful. Flicking up his hoodie to cover his head, the boy went into Zetsu before casually slipping into a crowd of morning commuters that filled the street.
"Oh, how precious." Hisoka knew he could break Killua at any time. The only question was when to do so. If he did so now he'd anger Gon and Illumini, but only Illumini would presently be worth fighting. The Zoldyck's death, however, could spur Gon to ripen faster. Timed correctly the Kuruta boy and the doctor could learn of his demise as well and be stirred into action. Neither of those two was worth his time, yet.
Killua was worth the wait. While he could kill him to force Illumi into combat immediately, that battle would be an overall lower payout. The Zoldycks saw potential in Killua, enough so that they bypassed his elder brothers and became the heir. Hisoka too saw potential in the boy and as long as the Zoldyck clan continued to prove competent he'd trust their judgment that Killua would surpass Illumi. After all the reclusive assassins would know best about their own internal affairs.
Their family politics and inner workings were of no real interest to Hisoka. All that mattered was that Killua was brought to his full potential. At that point, he'd be struck down in his prime sending the Zoldyck clan into despair. Each of them strong opponents Hisoka would gleefully embrace each one before tossing the broken doll into the trash heap. Covered in blood and his Elastic Love they'd be beautiful.
It would be a shame to lose such pretty toys, but there was no need to mourn them. They would have served their purpose, he'd have had his fun. Then for his toy box, he'd just need to find a new prettiest one.
