Review Detail of WalterWilliams_ in Duel World Online

I've been looking for this kind of novel, but it's not often that I've met this card game novel. At first, I secretly disliked Tantai a little bit because some rich people usually have their personal habits which is quite not nice. So.. yes, he's just like that. But then when I read and got to know more about him, I turned to like this character lol
