The classmates who looked down on him until yesterday suddenly start bowing down to him. Using his abundant funds, Ryuji tames all his classmates except Guest with money, intentionally isolating Guest. Finally, he succeeds in stealing Guest's beloved girlfriend, Saki Nakayama! At this point, Ryuji is ecstatic. He goes out of his way to tell Guest that he stole Saki, plunging Guest into the depths of despair!
