TheNayuta no Kiseki website was updated as of last week. The updates include more shops listed for the preorder program, and voice actor interviews for the main characters.
The following was also updated to the site as well-
A new silhouette was added (as above), but is easily assumed to be Laila from the second preview video.
Another character was added:
The mysterious swordsman working alongside Zext. He wears white and gold armor and has a mask covering his face. He acts to stand in Nayuta and Signa’s way with the use of his large blade.
A garden found in the center of Lost Heaven. A conspicuously large tower reaches for the sky from the garden, and within the center, two coffins can be found.
