ลูกเขยคืนถิ่น: ผงาดบัลลังก์ราชันย์

Kai, an orphan turned soldier, led Valerano's fleet to defeat the Kyte Empire. Recognized as King Eddy's long-lost second prince, he returned to find his wife Sara and daughter Diana enslaved by his in-laws. He crowned Diana a Countess, crushed a Kyte invasion with his Underwater Fleet, and exposed the traitors. After Eddy's death, Kai faced his brother Jake's treachery, summoned the Airship Fleet to obliterate the Kyte army, and was crowned king. Sara became queen, Diana princess.
