About K.O.3an Guo

After getting kicked out from their 24th school for starting fights and couldn't find another school that would accept them, Guan Yu and Zhang Fei thought it's God-sent that Liu Bei (the king) proposed to be their sworn brothers so they could enroll into the prestigious Dong Han Shu Yuan, a school exclusively for royalty, on the condition that they pay for his tuition. However, Liu Bei unexpectedly got injured and Xiu was forced to take his place. Though they enrolled, it didn't mean they attended the class in peace because they must survive the school's death traps and hostile invasion from warring schools.
