How many times do I have to explain it to you before you understand? It is no longer an ordinary cat." "I just brought my Erha here for a physical examination, and you charge me 10 million? You can obviously rob it!" "Sir, I have repeatedly emphasized that this Erha has now been renamed Frost Wolf. It is a rare pet beast with the ability of 'Ice Mastery'. Ten million is really a bargain for you!" "Then what the heck is the starting price of one billion for the sparrow you put in the cage? What fool would pay one billion to buy your sparrow?" "Oh? That one you're talking about has Suzaku's blood injected into its body. It's a divine beast! What's wrong with a billion? Don't take it if you can!" ...
