"This is my kingdom" Shin or something
Kingdom is one of the best longest running mangas to date, I'm in love with the characters and the art is amazing. To start with, this manga is both somewhat a generic shonen and a generic seinin at the same time, it has elements from both and incorporates them really well. If you're looking for a full on militaristic strategy manga, this is your best bet, as we get breakdowns of everything going inside the head of each general, each strategist, and each warrior. I have to say the art is good enough for anyone to instantly be interested, despite the fact that at some points the scanlations just are really bad and overall take away from the experience of the manga, despite it being so great.
Characters: Easily the best selling part of Kingdom are each of the generals we meet throughout the story. Every general in the manga feels important, every general fells like they have play their own role and are different from the previous or next, and are easily some of the best characters in all of manga. To start with, the great generals of Qin are all unique and are so fun to read, with the only boring one being maybe Tou, but even then his convictions are great and it's awesome how we see him despite his initial appearance of just Ouki's vice general. I have to say, Kanki is easily my favorite character in the manga. He holds this sense of badass that no other character does and I love how they paint this character differently from how a character like him usually would, someone who tortures everyone is usually seen as "theres nothing behind his eyes" or that he has no path, but we see that he is burning with rage, and that everything he does is a way for him to outlet his rage and anger out on people who've wronged him and who he believes are in the wrong as well. An amazing character through and through, with some of the best arcs and some of the best moments. Another great general is Moubu, someone who isn't a great strategic general but makes up for the fact that he is the strongest and most powerful general, and his mace is the coolest weapon ever. Overall the characters in this manga are a 10/10.
Plot: The plot in this manga is really great at times, and feels really bad at times. The first arc is really boring for a lot of people, and chances are you won't like it either, but if you are able to push through it and read to the first war, it's amazing. The initial arc feels like it was supposed to be a lot more shonen than the direction they went, and it feels kinda jarring if you reread it after reading through the whole thing. Another issue with the plot is one of the characters, Riboku, who is the center villain and sometimes just feels really bs with his plans and how he's able to still be as important despite losing so many times, it's frustrating. Despite this, a lot of the poltiics in the manga are fantastic, and Ryofui is an amazing character despite not even being a general and just being a political figure. Overall, the plot is an 8/10.
