Vincent called in the strongest huntsman he knows, Heather and Yang to have them go on a mission to travel to another world to fight two dangerous creatures. He figured since he was able to make portals to other worlds, he should use it to his advantage and send the huntsman and huntresses to worlds that probably need help of dangerous creatures. These creatures were demons. Powerful ones. The reason for him not calling Yin instead is.... Ruby forced him to come to a family reunion and have him cancel the mission. So he decided to call in Yang and Heather. Once they agreed, their lovers decided to come if these creatures were indeed dangerous. But there was a problem. They had no one to watch their kids. So with no choice they had to bring them. They soon found out these demons aren't so dangerous after all
