ehh i don’t think he’s indiscriminately attracted to little boys. i always saw his attraction to gon as just an extension of his attraction to people who could kill him and used narratively to show how he’s so far gone into this addiction that he won’t exclude kids as targets, but not that he favors kids
I mean I did too, but what about during greed island when a phantom troupe told Killua’s younger sister “don’t get too close to him. We know his tastes (or types or something like that)”. I used to defend him that he could get horny by just a good fight and not kids, but he makes it kinda hard to defend him
