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.
One popular Sunny x Hitch fanfic could be 'A Meeting of Minds'. It explores their relationship in a really interesting way, showing how they might interact and support each other in different situations. The story has a great build - up of their friendship which could potentially turn into something more.
The central character is Omori. Alongside him, Aubrey is an important character. She has her own personality and role in the story. Kel is another friend, always bringing some energy and a bit of naivete to the group. And Hero, he is also one of the main characters, with his own story arcs and relationships within the Omori story.
