have you think of introduction bell in this Arc, and how much time is left before the starting of original ( I mean timing where danmachi story originally started ) , and will bell become a part of hestia family.
if yes are you planning to make him as strong as silver
Do you plan to have Silver create secret tunnels inside Orario? I say if Evilus does it, that prevents Silver either at least as a contingency plan for the events of the Zenos or Knosso
