While the focus was on the novel, I had missed that a manga adaptation was being prepared for that.
Revealed as part of the Kadokawa Sneaker Bunko 30th-Anniversary Festival event at the time, a new project was set to come out on April 1st, 2019 with Record of Lodoss War: The Pledged Diadem but ended up with an August 1st, 2019 debut.
It’s been a long time since we had anything new on the novel front from the Record of Lodoss War property but we learned earlier this year that something new is coming.
