For a book titled Dream of the Lion King, this surprisingly isn't a story about Fourier so much as Crusch and Ferris.
Of the five short stories, I liked the first, fourth and fifth the most. The second and third were just okay, though they made me laugh a few times.
Not much to say, this book gives more insight into Crusch and reveals Ferris's past. Julius gets some backstory too, though nowhere near the level of Crusch and Ferris. The last story deals with the inevitable death of the royal family, my eyes were damp a few times, but I wish there'd been more focus on Fourier. Outside of the first story he barely has any scenes from his pov. Not much is learned about his family or his life outside of Crusch and Ferris. Like what was that Sage thing even about?
So this was fine but the short stories were hit or miss for me. I did like taking a break from Subaru's story and learning more about the side characters. I'm pretty excited about the next vol, seems like it will center on Wilhelm when he was younger (unless I'm mistaken? I tried to avoid spoilers).
Something odd, according to the author's afterward this came out after vol 6 in Japan, but here in America it came out after vol 5.
