The crown prince knew of Hiro's inclination, making deals with this bastard was extremely hard as he was cunning. Keeping personal matters separate from business, in deals and trades he even gave Alan a run for his money.
The Apocalypse zone's monster materials were one example. Dylan repeatedly begged to have Hiro for the right to sell the materials, but even with their relationship Hiro never let up.
The butcher gave a portion of the money to Dylan to rebuild Partisan. But as he was among the reasons why it was destroyed in the first place it was hard to not be greedy.
Only one group of people could get anything they wanted from Hiro with no strings attached. And that was his wives, sister, and daughter. Anyone interacting with Heaven Sword would see the stupid faces Hiro made when he interacted with them.
