A young prince is forced to flee his kingdom after a betrayal and must gather a band of loyalists to take it back. It captures the same feeling of reclaiming a throne through wit and steel.
Why it's similar: This series mirrors the political struggle of Sei and the military growth of Shin. It focuses heavily on how a small, talented group of advisors can outmaneuver massive, disorganized armies using superior tactics.
Power comparison: Like Kingdom, the battles are grounded in reality, though the generals possess near-superhuman sword skills. There is no magic system, only strategy and individual martial talent.
Why watch after Kingdom: Watch this if you enjoyed the early arcs of Kingdom where Shin and Sei had to build their influence from nothing.
