First of all, I must point out that the author is YTMND YTMND , but she did not post the article herself and this has led to confusion in some cases.
The second thing is that this is one of my favourite anomalies and I found it a bit of a shame that there is hardly anything more about Isabelle and I feel it has potential for more. The author has also been inactive since 2019, so there's unlikely to be anything from the original author anytime soon.
That's why I wrote the tale "A Strange Daydream, As Sweet As Poison", which is set in the Japanese Foundation Collective Canon, as well as in my own Project Trickster.
