I can confidently say that it has 12 volumes in total. The series starts off with a strong focus on character development, and by the third volume, the world-building really kicks into high gear. Each volume adds layers to the story, with the later ones introducing complex political intrigue and deeper emotional arcs.
What's fascinating is how the author manages to maintain consistency across all volumes while still keeping each installment fresh. The 12th volume wraps up the main storyline beautifully, though there are hints of potential spin-offs. If you're a fan of intricate plots and well-developed characters, this series is a must-read. The art style also evolves noticeably from the first to the last volume, making it a visual treat as well.
