The Assassin Hero (MHA x HXH)

Heroes? Hah. The idea was absolutely absurd to Killua. In his old world, heroes hadn't existed. People fought and risked their lives for their own benefit, not for others. And others knew better than to trust the powerful to look out for them. It was just the way it all worked. If you were strong, you could have everything you wanted. If you were weak, you died.
Here, it was different. Here, people willingly entrusted their lives to a bunch of strangers in tacky costumes parading across a screen, calling themselves heroes by taking down a couple of people the public felt threatened by.
It was ridiculous.
And... surprisingly peaceful.
But really, what did that matter to Killua? After all, his only goal was to get back to his world again and find Gon and Alluka.
And he would do anything to make that happen.
