Humans are treated as the lowest‑ranked beings in the orc kingdom. To save his seriously‑ill mother, low‑born half‑blood gladiator Caius enters a knight’s contract with traumatized Serpent Prince Zeno. Starting from mutual hostility and suspicion, they resolve misunderstandings and grow attached through shared hardships. Caught in fierce court schemes plotted by the human Queen who seeks to seize power, the pair join forces to crush her conspiracy, right past wrongs, tear down racial hierarchy and build a brand‑new realm of equality for all races.
