It was a normal day in Morioh, well... for the residents. There was a new lady moving to town. Rumors say that she knows who your soulmate is and can help you find them. Jonathan, the oldest Jojo, decid koi I'lled to visit with his friend, Speedwagon. The two walked towards the door and knocked on it. The door opened and saw the old lady. "You two must be Jonathan and Speedwagon." "Can I help you?" She asked. "Yes, rumors have been going around that you can help us find our soulmate." Jonathan said. "Ah, then come on in, I'll make some tea." The lady said and walked in her house. The two walked in the house. "Wow, your house." Speedwagon said. "Yes, yes, I know." The lady said. The old lady showed them to a table. "Sit down, I'll get the tea." The lady said. "Thank you miss with such hospitality." Jonathan said. "Your welcome, also call me Jewel dear." Jewel said. "Okay, Jewel." Speedwagon said. Jewel came back with a teapot and three tea cups. Jewel poured tea in all of the cups and Jonathan and Speedwagon grabbed the cups. Jonathan took a sip. "Your tea is delicious Jewel." Jonathan said. "Indeed it is." Speedwagon said after taking a sip of tea. "Thank you," Jewel said. "Also, are the rumors true about you?" Speedwagon asked. "Yes, yes it is." Jewel said. "Why didn't you say anything?" Jonathan asked. "If you ask me about it I'll tell the truth and tell you your soulmate." Jewel said. "Can you find out who our soulmate is?" Speedwagon asked. "Yes, I can." Jewel said. She closed her eyes and put her hands on the table. "That's odd, your soulmates aren't human." Jewel said. Jonathan and Speedwagon got a worried look on their face. "Is that a bad thing?" Speedwagon asked. Jewel opened her eyes. "No, it's not, it's just rare for a human to have a monster soulmate." Jewel smiled, "It will be quite the journey to find them though." Speedwagon and Jonathan looked shocked. They have been on adventures before but nothing like this. "Do you know where we could find them?" Jonathan asked. "Of course I can, I just need to know if your family members have monster soulmates as well." Jewel replied. 

Then they heard a knock on the door. "I, Dio, would like to know if the rumors about you are true." Dio said. "Dio, we should just leave, the lady could be busy." Kira said. "No, I want to know, don't you?" Dio said. "Yes, but I don't want to mess in her business." Kira said. "Kira has a point Dio," Doppio said, "Maybe the lady is tired or something." "Don't worry Jewel, I'll handle him." Jonathan said. "Oh, it's fine, I know that you two aren't the best of friends but he wants to know and I won't lie about it." Jewel said. Jewel got up from her seat and walked towards the door. She opened it and saw all the Jofoes. "Yes, the rumors are true." Jewel said. "That's what you wanted." She was about to shut the door but Dio grabbed it. "I would like to know who my soulmate is." Dio said. "You'll know once you see her." Jewel said. "look here primative human, me and the Pillar men would like to know and soon as possible." Kars said. "Jewel sighed. "Do you need me to come over there?" Jonathan asked. "Is that Jonathan?" Dio asked in a disgusted tone. "Yes, he came for the same thing also." Jewel said. "Would you like me to give you something that could help you?" Jewel asked. "No, I want to know who my soulmate is right now." Dio said. "I'm sorry but Jonathan and Speedwagon are already here." Jewel said, "We can talk later over a nice cup of tea." "Fine, we will meet again at 7:00 pm tonight, don't miss our tea time." Dio said and walked off with the other Jofoes except Kira. "I'm so sorry for his aditude towards you." Kira said. "It's fine, people can be demanding a lot of the time." Jewel said. Kira walked off down the sidewalk. The rest of the Joestars saw what happened and walked towards Jewel. "Hey, um, did anything happen when Dio and his friends were near you?" Jouske asked. "Oh no, I'm fine, they just asked about the rumor." Jewel said. "Is is true though?" Joylen asked. "Yes, Jonathan and Speedwagon is in here for some tea," Jewel said, "Would you like to come in?" "I'm not a fan of tea but sure!" Jouske said. The group walked in and Jewel closed the door. 

The group saw Jonathan and Speedwagon sipping tea and talking about what Jewel said. "I got a question, do you know where they are?" Jonathan asked. "Actually yes, I have meet them before." Jewel said. "What's the old hag talkin about?" Jotaro asked. "Jotaro!" Jonathan said in an embarrassed tone. "It's okay Jonathan." Jewel said. "Now, I want all of you to put your hand on the table." Some of the jojos looked a bit confused. Jonathan and Speedwagon reassured them that it was fine. Jewel put her hands on the table. She started to chant something and things in her home started to levitate. "This didn't happen when she did it for us." Jonathan said. Then everything slowly fell back down to the floor. "What just happened?" Joseph asked. "All of you have monster soulmates." Jewel said. "What!?" All of the Joestars said. 

After that conversation about the fact all of them have monster soulmates, some of the Joestars (Specifically Jouske and Joseph) told their friends about Jewel and they came to see Jewel also. Everyone who is friend or foe to a Joestar has a monster soulmate. Then everyone goes on a journey to find them.
