Aquaplus recently revealed some more details about upcoming titles in its Utawarerumono series. The details begin with the announcement that the in-development action spin-off title is named Utawarerumono Zan, and will include the characters Kuon, Haku, Nekone, and Ougi from the Mask of Deception/Mask of Truth duology. The game will have a story mode but it is not yet confirmed what relation it has to the main games or exactly how the gameplay will work.
In addition, Aquaplus president Naoya Shimokawa revealed that further games in the series are planned following the upcoming release of a remake of the first game next month in Japan, with one already in development. No details were revealed, but he did state that there are as-yet unwritten stories to tell from before the events of the first game, as well as between the first game and the sequel duology that consists of Mask of Deception and Mask of Truth.
