Arino was hospitalized after he discovered an abcess on his lung. Returning to work for the first time, Kibe "interrogates" the Kachou. Afterwords Arino enters "recovery mode". The staff decides it would be cruel to subject him to a usual challenge so soon. So Arino casually plays Super Mario Bros, and ends the episode playing Dr. Mario's VS mode with AD Nakayama.
Not since Clock Tower has Arino played as a girl in a challenge game before, but this season we have The Madoola no Tsubasa, starring the female knight Lucia.
After three victories, Arino faces what could be his biggest challenge this season. The game before him is Namco/Falcom’s Dragon Slayer IV, known in America as Legacy of the Wizard. This action-RPG featurs a humongous mazelike dungeon, and a family of five, the Worzens, who must defeat the dormant dragon living beneath.
