My future manga/anime. Tell me what you all think.

Anime Name: The Demons Within.

Basic Idea: I wanted to base my anime off of 2 other animes: Kaiju No.8 and Monsters We Make. I chose these animes, because I love an apocalyptic world setting and the people fight the monsters wearing special suits they've made. That's basically what I'm going for. I'm also basing it off of Devil May Cry (talking about that next). So here's my idea: years ago demons came to earth and have caused a demon apocalypse, so the humans found ways to fight back by creating special suits to fight and weapons from demon corpses (the story is set in Japan).

How Did The Demons Arrive?: the demons arrived on earth through cracks (this is where the devil may cry reference comes in). In Purgatory, the demons began to rip cracks in their world and pulled themselves into the human world, and the more it happened, the bigger the cracks got and more demons pulled their way through.

Main Characters:

1. Akito Kugarane (protagonist): Akito starts off as a clearer in my world. One day, when doing his job with his friends, a demon attacked. He told his friends to run and get the executioners while he tried fending it off. He was about to die, when he unlocked a power that had been hidden for years without him sensing it, and killed the demon with ease. When the executioners arrived, they saw Akito standing on top of the demon corpse, shocked and surprised why what just happened. This motivates him to become an Executioner to save lives.
2. Makiro and Hinako Siyanomo: Makiro is the calm collected guy who helps lead Akito down the right path, while Hinako is the girl who loves Akito deeply. While Makiro is 2 years old than Akito, Hinako is the same age as him. The both of them are actually the 2 friends who Akito told to get help from the Executioners.
3. Daigo Korunome: Daigo is the more reckless guy of the cast. When him and Akito first meet during the tests to become an Executioner, Daigo already sees himself as better than anyone he comes across until Akito put him in his place. He's basically like a Bakugo, even going through his own personal growth as a person. (These are all the characters I'm talking about so far.)

Main Villains: my anime consists of only 2 main Villains. One is a one time villain while the other is the MAIN big bad that I'll talk about in my next post because I've been writing this for a while.

1. Mother: mother is the one off villain. Before the demon apocalypse, she was a woman who owed a lot of money to very bad people. Eventually, she had her 3 kids taken away from her and was obviously deviated. Instead of going to the police however, she decided to kidnap other children so they could be her own, however she didn't know she was killing them with her punishments for if they didn't listen. Eventually the apocalypse hit and she fended off the demons herself. She ended up pearcing one and it's blood went into her mouth, causing her inner body to go through a mutation, becoming I bio manipulating mutant. Using this new found power, she took 7 of her dead kidnapped childrens corpses and injected demon blood into their veins before incubating them. Eventually they mutated, going through their own transformations and becoming mutants at their own right, the 7 of them being named after a sin.

If you wish to know more, comment and I might talk about it on my next post such as the power system, second antagonist, etc. if you have questions in general, just ask.
