Despite Endea’s interference, Sid won the Premier Chevalier tournament. Alvin thus thought she’d succeeded in her bet against the empire, but things took an unexpected turn when Flora suddenly appeared and completed the ritual to make Endea the Demon King. Alvin must now gather an army to fight against her younger twin sister, but just before the final battle...Sid suddenly disappears! Just what is the truth about the royal family? Why does Endea hate Alvin so much? What happened in Sid’s mysterious past? And why was he reincarnated in this era? All the questions will be answered in the final volume of Magic Knight of the Old Ways!
