Gon's a girl ! Also she lost her nen ! Gon gets called for a job perfect for her since she lost her nen and Killua followed along to protect her from the unknown in that place ... But now ... They have to help a class of assassins ? Kill an octopus ??? I know a lot of you might not like gon as girl , but I have a good reason , you can just pretend that gon's a boy if you don't like it
