Zombies... not quite but probably close enough. They are infected, not undead, and if left on their own long enough they simply starve to death or die of exposure as they are not rational enough to even seek shelter or eat/drink. But they do go after non-infected much like a classic zombie.
I think Interim's story isn't really supposed to make a whole lot of sense yet as the MC is still mostly in the dark himself about what is going on and why. His "handler" hasn't really been to upfront with him to this point, though he's starting to force some more information out of her.
And I strongly disagree with the Sandbox tag. Sure there are choices to make where you can't make them all. Just like in any VN that isn't a KN.
Thank you very much for the info abt Now and Then, I appreciate it.
I agree that Interim isn't supposed to make too much sense so far, like you alluded to. Also, it's just so very early in the story and things will change.
My only quip so far might be that the MC's job is to process ? souls, for lack of any other term. He quickly helped a couple right off the bat but now it seems like he's collecting rather than processing which is opposite what he is supposed to do. Also the Dev mentioned (I think) getting rid of one of the LI's.........I think I read that on the patreon page.
The MC should only be allowed to have 1 LI, the handler, since everyone else is temporary and supposed to leave asap.
If he's not collecting, he's at least digging in for the long haul with the current batch of ladies which would seem like he's failing his job.
BUT, I'm also a big dummy so probably missing a lot, lol!
Cheers and Have a good one
