Episode List

For 15 years, a war has raged between the humans and demons. The humans' greatest warrior, Hero, heads to the castle of the Demon King, leader of the demons, to end the war. To his surprise, the "Demon King" is actually a queen and she has been waiting to meet Hero in person and wishes to talk with him instead. As they talk, she reveals the war has actually benefited both sides as their races have put aside their differences to fight against a common enemy and improved the economy.

After teleporting to the Human Realm, the Queen and Hero arrive at a small farming village called Winter Pass, settling at a villa with the help of her most trusted servant, Head Maid. To stall time for the war, rumors are spread that the Hero and Demon King fought and are recuperating their wounds. Thanks to Head Maid, the Queen is given a cover identity as a human noblewoman known as Crimson Scholar.

Some months later, the village has adopted the Scholar's farming methods. Crimson Scholar and Hero, now assuming the identity of the White Swordsman have a meeting with the nun in charge of the Lake convent in Lake Nation, whom they discover to be actually Female Knight, a member of Hero's old party. To justify Hero's disappearance, Crimson Scholar claims to Female Knight that she found him severely wounded from his fight with the Demon King and upon saving his life, he offered his protection in

The Fall season has arrived since Hero's departure and Female Knight has moved to the villa to teach swordsmanship to Crimson Scholar's students. A member of the Alliance, Young Merchant, pays a visit to Scholar and she introduces to him another crop, corn, which will help boost mankind's food production even further if the Alliance helps her fund the farming the crop.

At Gateway City, a huge city in the Demon Realm occupied by the Humans, Hero, addressing himself as Black Knight, saves a Demon barmaid from being harassed from Crusaders and learns from her how most of the Human army have mistreated the Demons since occupying the city except those who guard the Eastern Fortress.

Elder Sister Maid asks Crimson Scholar why war exists and the latter explains its causes. Meanwhile, with the help of fairies, the Black Knight causes nightmarish illusions to the Crusader armies in Gateway City, affecting their sanity and morale, including that of the Crusader Commander. The Crimson Scholar arrives at the Winter King's camp and offers her aid to him and Female Knight.

As the second summer arrives, the Winter Kingdom has improved significantly with the Crimson Scholar sending one of her students, the Merchant Youngster to help the Winter King. After training with Female Knight and tasting Younger Sister Maid's carbonated drink, the Hero heads back to Gateway City as the Black Knight to attend a festival. While feasting with the Eastern Fortress General, the Fire Dragon Princess, daughter of the Archduke Fire Dragon, arrives much to Hero's chagrin as the Prince

Young Merchant pays a visit to the Crimson Scholar's villa and by her instructions, Elder Sister Maid tries to impersonate her with the magical ring, but is unable to deceive him. Hero then intervenes and takes him to the Demon realm where he shows him that the now liberated Gateway City became a thriving metropolis inhabited and ruled by humans and demons alike and have the Fire Dragon Princess hold a banquet to them, where he offers him the right to explore the commerce in the city in exchange

Young Merchant learns from his sources that the Central church and Central nations concocted the heresy charges against Crimson Scholar as her work was helping the South being free from Central's influence. Taking action, he has one of Scholar's students, the Noble Youngster, help in his plans. Meanwhile, an Emissary of the church arrives to take Scholar into custody, unaware that she is in fact Elder Sister Maid in disguise.

The Southern kingdoms join forces to defy the Central nations by ending serfdom and lower taxes to encourage people to immigrate to the South and the Lakeside Convent separates from the Central Church to form the True Church of the Light Spirit with pamphlets and bards spreading their message.

As Young Merchant and Fire Dragon Princess learns that Central intends to install a new currency to prevent inflation, Winter King and Hero are informed an army led by the Blue Demon clan has emerged from the portal to the Demon Realm and intends to attack from the south. Hero departs to confront the Blue Demon clan alone, allowing the Southern Alliance to focus on the incoming invasion from the north and much to his surprise, he reunites with Female Magician on the way there.

Female Magician appears before the Winter King and delivers him instructions from Crimson Scholar on how to develop a vaccine for smallpox which might convince Central to make peace with the South. Back in the Demon Realm, Hero manages to help the Queen force out the ancient Demon Kings from her body.
