         6 . The game execution apparatus of  claim 5 , further comprising: 
 a character writing unit operable to, when the game execution unit changes the character's characteristic, overwrite the character data in the portable recording medium with after-change character data that indicates a characteristic of the character after changed, wherein    the character reading unit further reads the after-change character data from the portable recording medium, and    the game execution unit changes the character's characteristic as the game proceeds, in accordance with the read after-change character data.    
     
     
         7 . The game execution apparatus of  claim 5 , further comprising: 
 a writing unit operable to write the read permission information to the portable recording medium.    
     
     
         8 . The game execution apparatus of  claim 5 , wherein 
 the game recording medium further stores therein a degree of change allowed on the character, in association with the permission information, and    the game execution unit changes the character's characteristic as the game proceeds, in accordance with the degree of change stored in the game recording medium.    
     
     
         9 . A portable recording medium comprising: 
 a storage unit that stores therein character data that indicates a characteristic of a character that appears in a game;    an authentication unit operable to check authenticity of a game execution apparatus; and    an output unit operable to, when the authenticity has been ensured, read the character data from the storage unit and output the read character data to the game execution apparatus.
