They create suspense. As people listen to a party ghost story, they start to anticipate something strange might happen. For example, if the story is about a haunted room in the party venue, guests might start to feel a bit uneasy about the area. Also, it gives people a shared experience of being spooked together, which can bring the group closer and make the party more memorable.
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.
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.
