Some reviews for the novel are pretty bad, so even though I wanna read more, I'll just wait.
For those curious, people are saying Ahashi remains one-note, the dragon king gets so obessed over Ruri when he finds out her identity that it boarders on abusive, Ruri is a doormat, the politics and worldbuilding is nonsensical, etc. Although I don't usually just take others' word when they say a story is bad, I can definitely see this manga becoming unbearable if it took itself seriously like the novel seems to.
