Shirou never expected to be summoned to another world, but now all he wants to do is finish save it so that he could return home to his family. But it order to return home, he will first have to survive. First rule of surviving as a summoned hero, don't trust ANYONE.

For Killua Zoldyck, he couldn't care less about money, fame, or helping people. Becoming a hero was a means to an end. Along the way, he will get involved with Heroes and Villains while trying to conceal his immense power from either side. After all, how would they react to a child prodigy assassin with the ability to wield his own life force?

Because sometimes a tale is too tall not to tell. Even if no one will ever believe her, this isn't Riskua's first shot at life. It is her first time as the 'big sister' of the nuisance that is Monkey D. Luffy however. Self Insert. (slow burn on the pairing)

Even as she stormed through the world like an atomic bomb, Luffy knew she couldn't protect everybody with these two small hands. Of course she knew that. But she could try. With these memories of that other world, by god would she try. Fem!Luffy.

A final Wish from Alluka sent her older brother to a place where the Zoldyck family would never find him. Interestingly enough, this world has Hunters as well as people who have the ability to use Aura, but in a very limited way. Will seeing them waste there potential get on Killua's nerves? Will he help them discover the true power of Aura? Or...will he not care in the slightest?
