Intro. Killua Zoldyckis on a mission with Gon and the others to try and locate someone. It's been 13 years since he first met Gon but their friendship is still strong. Their search leads them to believe that the person is on the other side of a battlefield. The only way through is to fight. They do so and all 4 of them notice a beautiful woman who is commanding on the battlefield but also very capable. She seems able to use her nen to heal people and through that keep their side from failing to hold the line. She saves Killua's life when he should have died this intrigued him. Especially since she's so damn pretty.
