I just finished Harrison's route a few days ago so I wanted to share some of my thoughts 👀
THIS IS JUST A POST FOR FUN 🥺
SPOILERS AHEAD (just in case)
The premise of Ikemen Villain is that you are living in 19th century London. Crown works for the Queen. This would have to refer to the only female British monarch in that century, Queen Victoria, who reigned from 1837-1901 aka the Victorian era.
I think most people know by now that Arthur Conan Doyle (the non-vampire version) makes an appearance in Harrison's route. Harrison's day job is being an editor and he's also a big fan of mystery novels. He mentions enjoying Conan Doyle's novels and being excited for new releases.
Sherlock Holmes is also mentioned a few times in his route, and not just by Harrison. MC also references Watson (wish I had the screenshot for this, it was in the middle of Harrison's route 🥲). We can assume at this point that Sherlock Holmes has reached enough mainstream popularity as even regular, literate folk like MC vaguely know the characters.
Sherlock Holmes made his first appearance in 1887, meaning our setting is already quite late in the Victorian era. He became increasingly popular after having his short stories published in a magazine, beginning in 1891.
To add to this, Liam mentions Alice's Adventures in Wonderland (William's route, Chapter 2) and specifically says it is "a story released a few decades ago". That book was published in 1865. A few is usually considered to be 2 or more, confirming again that it is late in the 1800s (at least 1885).
Therefore, Ikevil takes place between 1891-1899. Of course, this assumes the timeline matches our timeline and it isn't in an alternate universe where things we know from history are sprinkled in here and there haha wouldn't that be funny 🙂
Honestly though, I do know that Cybird hasn't always been the most accurate when it comes to historical events (I wouldn't really expect that of them either). I just think it's fun to imagine that Ikevil and Ikevamp could be happening in the same universe ☺️ I would love to see a crossover event (I know there's one with Harrison and Arthur my two favs)
Let me know if you have a different perspective! I'm so curious if they added any other historical references in other routes. I just started William's and haven't done Liam's yet.
