The fabulously wealthy heir to the Tsuwabuki Concern, Ichiro Tsuwabuki, has arrived inside the next generation virtual reality MMO, Narrow Fantasy Online. His cousin Asuha has asked for his help in finding someone inside the game, and he's come to help her out.

Of course, while he's happy enough to help his cousin out, Ichiro also cannot be satisfied with anything but total mastery of whatever he tries. He quickly proceeds to dominate the game world using his natural genius... and his wallet!
