Iwano said that he has begun a "new challenge" this month, and noted that he has not been involved with the franchise's development for some time.

Square Enix released Kaku San Sei Million Arthur as its first mobile card game based on the folklore of King Arthur in Japan in 2012. South Korean publisher Gamevil brought the game to North America and Europe in 2015, after Square Enix closed the game's Japanese servers in March 2015. The Jaku-San-Sei Million Arthur four-panel manga debuted within the franchise's games in 2012. The first game inspired a live-action television series in 2014.
Square Enix released a sequel game, titled Kai-Ri-Sei Million Arthur, in Japan in 2014. Examu developed a fighting game titled Million Arthur: Arcana Blood, which launched in Japan in 2017. A PlayStation 4 version debuted in Japan last November. The game will get a PC release this summer. Kō-Kyō-Sei Million Arthur, a new smartphone game, also launched last October.
A net anime adaptation of the Jaku-San-Sei Million Arthur manga premiered in 2015. In addition, the Operation Han-Gyaku-Sei Million Arthur (Han-Gyaku-Sei Million Arthur) massively multiplayer online role-playing game inspired a television anime that premiered in October, and the second season premiered on April 4.
