The manga adaption got licensed in Germany, I can't wait to read it! I really would like to read the novel too, please license it J-Novel Club!!!
Overall the novel reminds me a bit of Pandora Hearts, maybe it's the dark touch and the mystery part the story has?
I've heard this be compared to 'The Empty Box and Zeroth Maria' a couple times, a work that was hardly known in Japan but beloved and hailed as hidden gem by its English readers, and from what little I've read, it does seem very charming... even if that tragedy tag scares me a bit lmao. Still, I'd welcome any good mystery, especially if it is one with a strong central character dynamic.
One of the OG, yeah. No Reincarnation / Otome game, but it seems to be the progenitor of the modern Villainess sub-genre. Released in Web Novel form in 2012, two years earlier than Bakarina from what I could tell.
Similar to the Girl Who Ate a Death God, this is a dark fantasy story that is more gritty and complex than most LN fair. It's one of the better LN I've read and it would be nice to see it get a proper adaption.
This is the sort of story that might appeal to people who like stuff like Overlord where morality comes in shades of grey and there is a lot of emphasis on big picture political struggles as seen through the lens of the character's perspective, large scale war and complex world building.
