According to the recently released cover art for Dengeki Playstation, it unveils that the next game in the Atelier series entitled “Project A14” will be entitled Atelier Ayesha.
Further information pertaining to the game has also been unveiled. This game will evidently feature alchemy, however does not seem to be as Alchemy based as the previous Alchemists of Arland series. The games main characters are named Ayesha Artool and Nio Artool who are sisters. The two will be voiced by Marina Inoue and Mariya Ise respectively.
The storyline apparently goes that Nio has gone missing leaving Ayesha behind. Having found some traces of where her sister may be, she heads out on a journey to find her. (Am I the only one feeling it sounds a tad similar to Atelier Totori?)
While nothing much on the gameplay has been announced, Dengeki unveiled that the game will allow you to connect memories together during her search for her sister, which will develop the character further.
