Can you explain this to me this
(Ayumi is useful the Ran,not only that and she is braver than Ran) and that the DB are more useful than Ran
For me i don't think that DB is useful (except Ai and Conan) and i think Ran is more braver than Ayumi and not only that Ran saved Ai from Vermouth, did Ayumi do anything like this.
Another thing Ran sloved 3 cases by her own
