Based on a popular 11-volume manga series from Japan titled 'Bokko'. Set back in the Warring States in 243 BC, China was torn among seven states. Smaller states often fell prey to larger and stronger ones as their ambitious rulers strived endlessly for expansion through invasion. State Yan was one of those unfortunate victims, with State Zhao eyeing them to feast on. To win though, they knew they had to take City Liang, on the outskirts of State Yan, in order to win the battle.
City Liang, population four thousand, was ruled by King Liang. Mostly farmers and civilians, the residents had no experience in fighting a war. King Liang's only chance of survival was to seek external help - the "Mozi Warrior", who was renowned for his war-winning tactics.
This "saviour" was a ragged, unkempt fighter and no knight in shining armer. But the people of the City had to count on him for their future.
