Studio Sunrise's Yatate Bunko website posted the poll results for which Sunrise anime series the website's readers most want to see continue. The Phi-Brain - Puzzle of God anime was on the list, and an unspecified leading staff member commented that a 5th anniversary project is in the works.

The other results of the poll are listed here.

The first Phi-Brain - Puzzle of God anime season follows Kaito, a puzzle-loving freshman at the private high school named "Root Academy." He is selected as a candidate for "Phi Brain" for his extraordinary mental skills. One day, he and his childhood friend Nonoha tackle the "unsolvable puzzle" hidden in the underground ruins near the school. They are guided by the mobile device given to Kaito by the student council president. In the second season, the story continues to revolve around the Orpheus bangle and Phi Brain, but the puzzle battles heat up.

The first anime premiered in 2011, and the third and most recent series premiered in 2013. Crunchyroll streamed all three series outside of Japan. Sentai Filmworks licensed all three series but only released the first two on home video.
