Tenka Touitsu Koi no Ran: Shutsujin! Saika 4-nin Shuu

Synopsis

Fifteenth-century Japan is torn by endless warfare among feudal lords seeking supremacy. After your father falls in battle, you help your mother run the restaurant he left behind, caring for your younger brother. A corrupt magistrate forcibly drafts your brother to serve as a poison tester in the castle. To shield him, you don a male disguise and take his place. But the trials that await you within the castle walls are far more daunting than you imagined. "I will demonstrate to everyone... the power of my divine rule!" In this Sengoku-era story, navigating the perils of love proves every bit as treacherous as the chaos of war.
