One common theme is friendship - turned - love. They often start as just friends or even rivals, and then gradually fall in love. Another theme is self - discovery. As they get closer, both Aubrey and Beca learn more about themselves. For example, in many fanfics, Beca learns to be more open, and Aubrey learns to be less controlling.
I'm not entirely sure who Aubrey Manning specifically is in this context. But he's likely someone who has a significant connection to the story about the Earth. Maybe he's a scientist, an explorer, or a storyteller.
I don't have the exact name of the person who created the Omori manga at hand. It could be worth doing a search on manga databases or asking fellow manga enthusiasts for the answer.
Omori is purely fictional. The story and characters were imagined by the creators, not drawn from real-life events. It offers a fantastical and imaginative experience for players.
At the moment, there's no definite date for the Omori manga release. But you can follow the official social media accounts or manga forums for any potential news or leaks.
