hello! I've been wanting to throw Killua at Leslie, and it seems the heroic rescue might be a great way to do that if you're up for it! he just turned 15 so they're close in age and he could use more friends, plus he's sad about his little sister not being here so if he sees a little girl in danger, he'd definitely help out! well, he probably would help in general, but missing his sister certainly helps with motivation, haha. :)
