See, the problem with Golden Kamui is that it's so good that I'm worried about having to adjust to the slower pace of most mangas.
Golden Kamui is one of the best stories I've ever read - take note: not one of the best mangas I've ever read, but one of the BEST STORIES over all genres and media (not too sure why this manga has an average of 8, can't imagine anyone giving it lower than a 9). The story is amazing; if you're put off with the thought it might be too "heavy" since it's historical fiction, the manga explains all the historical context well so you just have to sit back and relax. I don't usually delve into storyline because I always think it's better to experience it for yourself, so just take my word for it and try at least the first chapter.
The art is absolutely spectacular. I'm not a visual artist, but I am a biologist. Every time I see the art (of the animals, especially) I'm always so impressed by how well (and accurate!) they're all rendered. The direction of the layouting and pace is perfect. Golden Kamui's one of those mangas that can go back and forth between comedy and drama without it being awkward.
Most of the time, the reason I stick with a story is because of how much I love the characters. All the characters in this story are unique, I'm sure that you'll find all of them very interesting and entertaining. While the story is pulled by the main arc/goal of the story, I think it's still a character-driven story that allows the characters' quirks to shine despite the main arc.
To be honest, I was unsure about reading this at first as well. From the screencaps I saw, I couldn't really piece together what the story was about and I saw the comedy and drama moments in snippets so I didn't know what to expect BUT just let me say: it lives up to its hype!
