Review Detail of Kirigaya_Kazuto_1221 in God of Virtual Reality(Dropped)

After digging into so many books, I finally got a book like Sword Art Online. The Death Game Genre, I loved it and the author is just doing well. I hope the protagonist (Hector) gets mature and entry of other guy (Kai) made it more interesting. According to me Kai is the Antagonist... What do you all think???
