Norn9: Last Era is an engaging adventure game available on iPhone, designed as a fandisc for the original Norn9. This full-version game presents players with three distinct story parts that expand on the narrative of the original title. The first part, Concerto, offers two-part epilogues for each couple, allowing players to delve deeper into their relationships and see how their journeys conclude.

The second part, Fuga, takes a unique approach by retelling the events of Norn9 from the perspectives of the love interests, providing fresh insights into the characters. Lastly, Fantasia presents a hypothetical storyline in a universe where the heroines do not engage in romance, adding an intriguing twist to the overall experience. Together, these elements create a rich narrative tapestry that enhances the Norn9 universe.
