Like a Black Panther / Dear DIAMOND!! -The Eternal Brilliance of 101 Carats-

Original title: 黒豹の如く / Dear DIAMOND!! -101カラットの永遠の輝き-

Antonio is descended from legendary pirates who defended Spanish waters from evil during the Age of Discovery long ago, as part of the national policy. Employed as Chief of Staff in the Spanish Navy, he is known far and wide as the "Black Panther," given his qualities of being deep, flexible and quick. Someone respects, someone is awed by, and someone is planning to use -to further his success in life- this hard-line and quick-witted man.
