- Ambiguous Gender Identity: Kevin notes that he doesn't have any issue with disassociative effects like that when he sees a warning about the possibility of side effects when playing a character with a gender different than one's own in real life, implying that he might be gender apathetic or something similar. Kaylin's biggest issues with her new state seem to be from the memory loss and not being able to find any interested ladies than being female.
- Cat Girl: Nyna, a nekomata girl Kaylin meets.
- Cyborg: Mike, being from a sci-fi game.
- Deconstruction: As mentioned below, the story points out the flaws in how the society of a typical fantasy game would realistically work, especially when they all suddenly vanished.
- G.I.R.L.: Kevin's character is a female dark elf named Kaylin.
- Loss of Identity: Kaylin remembers the backstory in her bio better than Kevin's life and even remebers things he didn't write, to the point that she doesn't remember his last name. By the time she meets Mike she clearly does not consider herself and Kevin to be the same person.
- The Magic Goes Away: The disappearance of the adventurers seems to have caused, at least in the area Kaylin is in, a lot of magical knowledge/items to be lost. The magic academies were later revealed to have all been destroyed due to fighting over them.
- Mistaken for Gay: Kevin acts like he's gay when a customer gets mad for talking to his girlfriend, who is apparently a flirt. It works.
- My Rules Are Not Your Rules: Mike, being from a sci-fi game to an extent. On one hand his cybernetics still work and his gun is now extremely powerfull, on the other hand his ship doesn't work because it's item id conflicts with an item from the fantasy game.
- Normal Fish in a Tiny Pond: Kaylin was a high-level adventurer but was one of many, however in a world 200 years after they all disappeared, she's more powerful and/or skilled than anything that she's come across yet. She deals with Nyna's attacks with no real effort and wasn't even sure if she was seriously trying or not.
- Ontological Mystery: Somehow, Kaylin disappeared a century before the other adventurers did, only to reappear three hundred years after she vanished.
- Reality Ensues: As mentioned below, the adventurers disappearing caused a lot of issues, to the point that Kaylin's gold is so inflated that one gold coin is equal to 100 silver ones (which means they are 100 times more valuable than they were before), and towns had to drastically increase defensive efforts.
- In a less serious manner; Mike's cybernetics makes noises outside of human hearing range. But Nayna can hear them and, being from a fantasy world, finds the noises strange and annoying.
- Terminally Dependent Society: The society of the fantasy world was so centered on adventurers that when they disappeared, everything went to heck. Monsters stopped being slain, rituals and quests that the adventurers did go unperformed, and the economy collapsed because most of the wealth was in a system only they could access.
- Year Inside, Hour Outside: Apparently time in the game realm moves faster than in the "real world".
