Gods' Games We Play Novel Volume 5 was written by Kei Sazane.

After completing the supposedly impossible Lucemia labyrinth, Fay knows all eyes are going to be on him. He's even caught the attention of a mysterious, unknown deity. Uroboros, who had picked up on some fishy interference with the labyrinth, alerts Fay about this shady figure. However, there's no time to address whatever trouble is brewing. They are caught off guard when their next dive drops them into a basketball game against a whole team of gods! Of course, a typical human sport just isn't the gods' style, so the apostles will have to work together to face whatever variation these gods have in store.
