The Grand Fighting Tournament final fight is starting, the winner will be declared the strongest man in the world and gain fame and glory. Peter Grill reaches the final and wanting to impress Luvelia Sanctos, he manages to win, making him the first human to win in the last 150 years.
After winning, Peter heads towards Luvelia, but Mimi Alpacas from the same guild as him approaches him. She congratulates him and asks for a favor. Being in a good mood Peter is willing to listen, but gets shocked when he hears she wants babies from him. Mimi explains that as an ogre producing a strong offspring is a big deal and a champion like him is perfect for a breeding partner. He immediately declines, but Mimi doesn't give up. Lisa Alpacas, Mimi's older sister shows up and states that it will be she the one that will have his baby and explains that many nations and races will try to get his sperm. Unable to reason with them, he tricks them into looking away and uses the moment to run.
He heads into a church where Luvelia is waiting. She explains that her father had given them his blessing and they can marry and later have children. Peter asks her to remind him how children are made and she explains that when two people love each other, a stork carries their child. Peter finds her super innocent and blames the Guildmaster for being overprotective and brainwashing her. For the two years they have been dating, they were only able to hold hands.
That evening, after taking a shower, Peter finds Mimi covering herself only with a towel under his sheets, but throws her out. As he returns to bed, he then finds Lisa in a towel and throws her out too. They start knocking on the door, wanting to get back in and as they create enough noise and other people start to come out of their rooms, Peter lets them in to not cause any more problems. They explain they are aware about Luvelia, but also know they have only hold hands. Peter wants to remains faithful to Luvelia, but as the girls remove their towels and Lisa forces him to touch her breast, he loses control.
In the morning he wakes up with the two girls sleeping naked next to him. He starts crying for what he had done, and in that moment, Luvelia knocks on his door.
