Something bugging me in the plot: it only took the name of the "server" for Nova to find the world and create an access, but they never tried it for Calypso's world, at least they were never shown trying it. No one asked Idriel either. it should at least be a single line of text to show that they did try and close a potential plot hole.
is there a chance that Idriel is Queen Anima? and her ability to travel between worlds is exploited to run the game ?
and the cliffhanger for the latest update, I think Calypso will feel MC fading, as she is meditating with full awareness on outside worlds, and she will bring him to her and go to him to cast healing magic. she might be stuck on Earth if she goes there though. not sure if she can pull magic from Earth, but not impossible if the Founder could travel worlds unassisted. if it's just MC being treated in a hospital and getting back on his feet after a week thanks to his powers, I would be very disappointed. though, it could be MC brought to a hospital, all the girls rushing to him, doctors dropping the news that he is dying and it's impossible to revive him, and one girl has the idea to ask Calypso for help if they believe the game is real. at least, that way, the girls will be forced to evaluate their feelings for MC and sharing with each other how they feel about him
Also MC is pretty dumb for turning his back from two enemies that haven't lost their will to fight. literally anyone would watch them leave, or keep an eye out while leaving. would have made more sense if he saw the guy pull out the gun and couldn't react to it
