Before long, the nation of Naia, born from that very coup, suddenly launches an invasion against Ortenos. For the sake of his adorable sister, and to protect his sweet lovey-dovey life with his charming wives, Shalka takes up arms to defeat the enemy nation and restore the Kingdom of Ortenos…! Thus begins an otherworldly harem war chronicle!
