Unravel a Case Tainted By History and Obsession in the Solo-Developed Visual Novel Knight Case Files
The dark fantasy visual novel's release date has been announced!
Japan, 18th Nov - Hyokan Studios is proud to announce the release of the ornately retro dark fantasy visual novel Knight Case Files on Steam on November 27th, 2025.
Coming back to life was meant to be a fairy tale, but a few knew the truth
Set in an alternate 19th-century kingdom, this fantastical procedural story follows Wilhelm, a rookie knight in service of the Phoenix Kingdom, as he unravels and confronts a necromantic conspiracy. The story is brought to life with partial voice acting with a deep production that is anything but modest.
Bad endings are not the end of this story. A wrong choice shows a potential future from the perspective of the story's mastermind. Using the information found behind the bad endings, you must put together what you learn to finally put a case coloured by the past and obsession to rest. Depending on your choices, there are four different endings to the case.
By the end of the story, the characters have transcended the metaphor of their roles to become living, breathing beings with complex relationships.
A Unique World to Explore
Set in a 19th-century-inspired low fantasy world, the history of the world has been shaped by two ancient tribes: the Phoenix Clan, whose members die and resurrect from the ashes every 500 years, and the Serpent Clan, who attained immortality through the use of forbidden magic and science. The Serpents once used the bodies of the other races, including those of Phoenixes, in their immortality research. The Phoenixes retaliated against those crimes, and the kingdom's history still rings with the echoes of their war.
Bad Ends are Not the End
Reaching an unfortunate ending is not a failure in this game, but a thread in the grand narrative. Looking behind the curtain, or from the eyes of the story's mastermind, a bad ending still reveals a truth about the world. These explorations of the world span over 10,000 words. Using the information found behind the bad endings, you can find the path to the golden ending and understand the needs of all the characters.
Bad ends offer the chance to loop back into the normal game, allowing you to focus on the story without going through tedious replays.
Sparkling, Faceted Characters
Inspired by fairy tales, the supporting cast range from a newly-reborn immortal and the twisted Phoenix obsessed with him, the gender-bending alchemist with secrets to spare, and the innocently cruel girl finally free to explore the world. Every character of the story has a deep backstory and is entwined in complex webs of relationships that colour every word they say. The characters' inner lives are revealed through the story, the bonus unlockable tips, and the talented cast of voice actors.
