We have not heard from Square Enix yet but new reports are suggesting that Square Enix might be making plans to develop an I Am Setsuna successor.
This rumor started after the company filed a trademark for the title Kimi to Kiri no Labyrinth. While it does not seem to suggest that it might be related to I am Setsuna in any way, some fans pointed out the game of the game is similar to the Japanese title of I am Setsuna. In Japan, I am Setsuna is called Ikenie to Yuki no Setsuna.
Fans pointed out the style of the title with the use of “to” and “no” could means that this new game might be related to I am Setsuna. Of course, we might all be reading too much into it.
Hopefully, more details about this new mysterious game will be announced soon.
