Lost in time - hxh x mha -

In a new world, Killua and gon find themselves fighting with outdated principles and long since expired knowledge. They get roped into nezus scheme to trick them into using their true strength to prove to aizawa the power of the so called myths from the legends guarded solely by only the most trusted of the heroes. But why are these once celebrated legend's stories now so guarded? And why do these two gays - sorry I had to💀😭 - suddenly in this confusing new land?

Important
-This begins after gon and Killua leave the heavens arena - which is altered slightly to better fit the plot- and in the mha world, it is set when class 1a are in their second year - after the final battle and they are now class 2 a.
