The following were some recommended anime opening invincible system novels: " The Ultimate Animation System "," Invincible from the American Comics "," I'm Invincible at the Beginning "," Sacrifice at the Beginning, I Sacrifice to the Evil God!" "Kissing the Rip Girl at the Beginning","All the Races Cry, Humans Are Definitely Cheating!", "Heaven-defying Comprehension, Self-created System at the Beginning","Nascent Soul Formation at the Beginning, I Don't Really Want to Heaven-defying Comprehension", etc. The protagonists in these novels had invincible abilities or systems at the beginning, which allowed them to gain a huge advantage in the anime world.
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.
