I wanted to nominate either Empty Land or Occidendum. But it looks like they've received a lot of love already.
So, I'm turning my attention to another story I've recently enjoyed. The backgrounds are beautiful, the characters - though much, much better drawn, somehow remind me of The Magician, and the story starts with urgency and action. Lycoris Rising by @DaphnePanda
Sixteen episodes in, with consistent updates. Good luck to you!
@KillianRain @Fuzed I love your stories. Wish I could've been the first to nominate it! ^^
