The Human King(HK), the Guildmaster(GM), and the Demon King(DK) meet at the conference. At the conference the HK seals the conference up from the world so know information can come leave or come in. HK then tells the DK that he has joined forces with the Beast Kingdom. The HK then proceeds to tell the DK by this time the Demon Kingdom should be at war and how he sent his armies along with the Beastmen armies to destroy the Demon Capitol. GM gets pissed of at HK and can't believe that he would start a war. HK tells GM that he was never going sign a peace treaty since he has sacrificed to much including his own daughters to destroy the demons and that even his daughters would want this. Which infuriates the GM even more as the king didn't have to sacrifice his daughters in the first place if he just sought peace. They break out of the conference where they are surrounded by the Beast King and his men. Kiria then proceeds to stabs the DK as it turns out she is a traitor.
Meanwhile as the conference is going on. We find out that the heroes on the bridge are fakes and the real heroes are leading the Beastmen and Human armies to the capitol. The heroes with their naivety think they are just going to surround the capitol and make them surrender. Which they are then given a dose of reality as that was not the goal as the armies then proceed to massacre the city as the watch on as even demon children are killed in front of them.
Hiro seeing as the city is under attack and has a contract to defend the city is confused by what the contract actually entails him to do. Hiro then proceeds to teleport the DK to find out about the contract. He heals the DK and proceeds to rescue the Cruels and brings them back to the demon capitol. Hiro, DK, and Cruels back they then save the capitol and captures 2 of the 4 heroes. The male hero and one of the female heroes wake up in the place where the Cruel who is a painter is locked up and you are introduced to the person who is behind everything.
