All of these King Candidates, but only one will become Solomon's Heir and 'inherit the earth'. Sinbad commands 7 Djinn and at least every worthy person can command at least one. This will become a case of Magi-lander in some fashion. Most will fight, others will just submit. Most people will pick Sinbad to become the next 'Solomon' but ... Solomon's expy has already chosen someone else.
End of manga? Hardly.
