Daichi Mori has one kid who's a child of Hecate: Tora Mori. A year passed when Daichi had Tora with Hecate and things were going smoothly. Hecate was also feeling a bit lonely so one day, when Tora was with her aunt, Hotaru Mori, she secretly visited Daichi again when he was alone so she can spend some 'alone' time with him. Daichi was surprised at first to see her there because he thought he'd never see her again after they had sexual intercourse. When Daichi asked her what she was doing here, Hecate just told him that she secretly went to see him because she really missed him. Before they knew it, things started getting intimate and they had another 'hot and steamy' night together (>.<). When Daichi woke up, she was gone. A couple months later, Daichi was taking care of Tora and someone rang his doorbell. There was a basket in his front doorstep and in the basket, it revealed a baby wrapped in warm pink blankets. A letter was inside for him from Hecate and it explained that they have another kid. (As well as a ring for Miyako that turned into a celestial bronze mace) Daichi certainly was fine having one baby and Tora was good enough for him. Since he wasn't up for dealing with two demigod children, he asked his sister to take care of her. Hotaru agreed since she has always wanted a child of her own. (She knows about Daichi falling in love with a goddess and that he has a demigod child so yeah)
Miyako was a very popular person but also very scary to be with. Since she's very selfish and got very upset when nobody gave her what she wanted, she was often avoided and that was the reason why others thought she was 'scary'. Hotaru spoiled her child and gave her all that she wanted. With that, Miyako got to learn acrobatics as well as karate. Other than that, her school life was fine. When Miyako was 11, she received the ring Hecate gave to Daichi to give to her. (but she believes that it is Hotaru's aka her 'mother') But when Hotaru and Miyako went to visit Daichi and Tora, things would always end up bad for the both of them. They got in trouble a lot because of Miyako since she was always picked on her and made her feel less inferior since Tora was the family favorite. (Even Hotaru liked Tora a bit more than Miyako)
When Miyako turned 13, she had her first monster attack. A harpy attacked her and she started screaming. She thought it was the end of her life and panicked. Hecate came into Miyako's mind and told her in a very calm and soothing voice to calm down and morph her ring into her mace. Once she heard her mother's voice, she immediately morphed the ring she was wearing into a mace and attacked wildly at the harpy and it eventually disintegrated. She immediately ran back home and tried to forget that monster attack ever happened.
When she was 14, she had her second and final monster attack. A chimera attacked her and this time, it was a bit harder to disintegrate. It took her sometime to fully disintegrate the monster. But nevertheless, she disintegrated it. She had enough of this freaky monster business so when she went back home, she demanded Hotaru to tell her what was going on. Knowing that her two options were either to say she was hallucinating and she needed help, or to say the actual truth. Hotaru chose to tell her the truth... All of it. Instead of lying to her since she didn't want to make Miyako feel bad. When Miyako heard that Daichi, whom she thought was her uncle the whole time she was living, was actually her father, she couldn't believe it. She didn't want to be related to Tora because she just didn't like her. She never liked her. When Hotaru told her of the camp she was supposed to go to when she was older to get some training done, she immediately said she wanted to go. She wanted to be very far away from her family right now. They packed her things and she left to go to camp where she got claimed as a daughter of Hecate.
She stayed for camp the next year and turned 15. When she was in camp, Miyako was really popular with the guys because she often slept with a lot of them. Sometime when she was staying in camp, she suddenly started feeling the need to make herself look desirable and sexy. One night, Hecate came to her in a dream and told her to go on a quest for her. She was so happy and invited three of her best friends to come and join her on this quest. But as they were in the middle of the quest, things started to get very hard and rocky for the group. They were fighting at least 4 empousai and all of Miyako's friends died in the fight and she was the last one standing. Miyako was crying really hard after that fight and decided not to complete the quest for her mother anymore because of that. She went back to camp with the depressing news and shut everybody off. She then started feeling a lot of hatred for her mother and decided to run away. But she knew she had another option as well. The option to go to the Broken Covenant. One night, she packed up her things and quietly left the camp and tried to find the BC because she knew it was close by camp. After a couple of days since she left camp to go search for the BC, she was starving and was sick from a fever. She almost died just trying to search for the BC but was saved by Marina Sanchez. Marina was looking for any demigods who might have been roaming around the BC to recruit them into the Ortu Justitiae faction. Marina was at first, a bit unsure about Miyako because she seemed as if she was still on the gods' side. But after Miyako told her her life story, Miyako started gaining Marina's trust. Marina asked her if she wanted to join the Ortu faction and Miyako agreed since their ideology is hers as well.
