Rather than following up on X's cliffhanger ending, it appears that Monolith are going for an original story. While the presence of a planet-sized giant and a red sword with a glowing crystal in its hilt brings to mind the two titans and the Monado from the first game, the setting seems to be much more fantasy-based, with no sci-fi elements seen yet.
More importantly, the character designs are being handled by Masatsugu Saito, a hentai artist who also did Celica's DLC artwork in Fire Emblem Awakening.
