Im looking for something similar with Rakuin no Monshou. The storyline doesnt have to be similar, but I want a novel that has war and politics, strategy, possibly some action and a bit of romance. anything is fine as long as its not sci-fi or mecha. Because I prefer swords and magic more... (some simple guns is allowed too)
hmm~ Altina the Sword Princess Genjitsushugi Yuusha no Oukokusaikenki. Mei Gongqing Common Sense of a Duke’s Daughter Risou no Himo Seikatsu
