Several months had passed since Hero's departure and Female Knight moved to the villa to teach swordsmanship to the Crimson Scholar's students. A member of the Trade Alliance, Young Merchant, pays a visit to Crimson Scholar and she introduces to him another crop then unknown in the Human Realm, corn, claiming that it will help boost mankind's food production even further. Before leaving, he proposes to Crimson Scholar much to her embarassment. With half a year since Hero left to the Demon Realm, the Queen's anxiety increases, unaware that he has made use of his teleportation skill to return regularly to the villa behind her back, a fact only known by Chief Maid, to whom he confesses that he refrains to meet her out of his drive to become useful to her. Meanwhile, the southern nations are assembling a huge naval force to recapture Aurora Island, the only territory in the human world in possession of the Demon Army.
