A powerful Overlord-class Ethereal forced several squads to retreat, but Yan Fei ignored the withdrawal order and fought alone to keep the monster occupied. Miyabi arrived moments later, and the two fought back-to-back—Miyabi's precise, frost-infused swordsmanship perfectly complementing Yan Fei's relentless Fire Ether assaults.
