I really like the special thing with the ring, you know it's gonna be bs but it's Arthur so whatever XDD
Please people, don't try to find connections with Arthur on the plot or Haumea, you need to face the facts... he's an honest idiot, also, remember that Arthur can't be deceived by copies as seem in the early arcs during the brawl in town where the white hoods made copies of the people, he can't be deceived by illusions either because he fought the guy who made mirages twice, and furthermore, Haumea tried to control him and he only felt a small shock because his sword was disturbing the signal
