You were married, forced to married a human woman, her name was Alina. One day, she announced that she was pregnant with your child. Unfortunately, you felt that you weren't ready to take care of a kid, so you ran away, abandoning everything to begin a new life at another village far far away.
You lived inside this new village for years and Alina became a distant memory, until a army of monster girls arrived. The army raided the entire village, men were taken as husbands, including you, you met your new wife like this. You, your wife and the army moved to another location, creating a new city.
Time passed and your wife became pregnant with your children, two twins. You never told your wife that you actually had another lover and kid in the past, you hoped that it would be a secret forever buried. This time, you felt ready to raise children, it's not like you had any choices anyways, monster girls have a strong sense of family.
Time passed again and your daughters became teens, you were happy, life was perfect...Until you heard some worrying news. Apparently, a new Demon Lord is raising. At first, there were rumours about a Demon raiding villages and cities, transforming monster girls into their forms of the Old Ages. Hellhounds were transformed into real monsters, their lust replaced by bloodlust, mersharks transformed into terrifying marine monsters, oomukades transformed into giant man-eating insects and etc.
This attracted the attention of the current Demon Lord and her husband. The monster girls kingdoms were put into alerts and they prepared for war against this new threat. Even the Order and human kingdoms were under danger.
One day, you heard that the current Demon Lord and her husband, along with their army, marched foward into the home of the new Demon Lord, his name is apparently Alaxel. The results of the battle were terrible. The Demon Lord and her husband both together fought Alaxel but were defeated and forced to retreat. Their army was also forced to do the same as it was overwhelmed by Alaxel's own army. Things were not looking good and it was probably going to be worse. You feared for your city, for your family, you hoped that this Alaxel wouldn't come here.
Your hopes were crushed when one day your heard your door being knocked when your wife and daugthers were away doing shopping in the market. You met a man who claimed to be your son, his name is Verdarmir. After he proved to you that he's really your son by divulging informations about Alina, he explained to you that Alaxel and his army are planning to come here, they're coming to raid this entire city...coming here for you.
He also explained to you that Alaxel is his brother and thus, also your son. Yes, it seemed that Alina wasn't just pregnant with one child but two. You asked him many questions. How did Alaxel became how he is today? Why is he coming for you? Etc. Apparently, Alaxel became like this because his soul merged and became one with the soul of a ancient Demon Lord. Or was it the soul of a forgotten God? Verdarmir claimed to not really know. Either way, Alaxel was only 5 years old when that happened. He gained powers that matched even the Gods and throughout the years, he learned how to control them. Verdarmir explained to you that his bother always hated you for abandoning their mother. He told you that when Alina died of illness, he and Alaxel parted away to live their own lives.
You then asked him how does he knows that Alaxel is coming here. Before Verdarmir could answer another one of your questions, you heard the door of the house being opened and someone yelling 'We're home, Honey!'. Your family has returned.
What do you do?
