Heaven's Fated Gate
Heaven has written an immutable decree for humans and the entire cosmos, locked behind Heaven’s gate. A brilliant and cunning scientist views this divine threshold not as a holy land, but as an untapped energy source—a backdoor for immortality, a “flawed law of physics” and “control room” where they claim it needs to be rewritten.
To stop this, an unlikely quartet forms a cosmic heist team to stop this scientist and to preserve the reality and fate of humans. Tenshi, described as a “fallen angel”, provides a blueprint and insider knowledge of the gate. Catzil, who manipulates Time, acts as the team’s ultimate wildcard. Caleo, a human accompanied by a demon named Abraxas who feeds on lies and must use their intellect to side with a fallen angel and a cat to stop a fellow human who is trying to save the world by illegal means. Ruby, who was given the role to spy on Ajh, who gives information later on, and has a massive role in coming up with a plan in the end.
The cosmos’ fate is locked behind a gate, and the scientist, Ajh, claims that it will cause a cosmic calamity and that science must break fate to save everyone, even if it means sacrificing millions of people. Breaking the Gate to rewrite fate will cause an even worse paradox, or the calamity is a natural, necessary cycle of the universe that cannot be tampered with.
Catzil has traveled to the past because she saw the horrific timeline after the success of changing the fate of the world by the scientist during her “present”, and decided to ultimately go back in time to prevent that specific future. During this time, Catzil drains her skill, which caused it to be nerfed because of the amount of cosmic power to rewind time after the catastrophe it brought upon her “present.”
Caleo (and Abraxas) is stuck between a moral dilemma at first, but when these two individuals spoke about the impending doom of the cosmos resetting, he decided to help them. Using Abraxas, who can tell lies, he seems to trust both of them and decides to help them despite knowing what will happen in the future—the death of humans.
