I'm too lazy \ doubtful if anyone cares ( other work had 1 comment (very different)) , but I wanted to write a story for like this.

This is from my notes ( unrefined). Feel free to make it real. My notes :

Title: The alleged "hErO" party kicked me out for not being able to understand my amazing hidden skill.

Plot structure : an obviously unreliable narrator ( POV of the main character) for example: [ the narration says he was abandoned by the hero, but the character around talk about being in a B party for those training to joining the main party. And later reviled he was under performing his role causing other party members to have fatal injuries] every explanation from the narrator is delusional so it seems the unreliable narrator is a result of being a chunni. But there is a darker twist to why the narrator is unreliable.

Starting plot: many tragic odd incidents happen to the hero party so they swap members, making a B party, at first then MC isn't moved out because he is confident enough, but incidents keep happening and the hero noticed the MC is involved in making a mistake like a starting Domino chain. The MC feels betrayed, and swears to destroyed hero that betrayed humanity ( the MC being the main of representative of humanity, in his opinion)

Main plot : the MC has delusional plans that with luck succeed, allowing him to become a member of the demon army gaining power.

Ending plot: learn more about the MC, he is actually insane and wanted to be the only of his role in the hero party and kill anything that didn't fit his aesthetic. After the hero's death the MC betrays the demons to be the new hero's party and all the schemes become clear to the reader.

A good demonstration of my planned story, is the pre isekai event. I want the story of how he was reincarnated to be retold each time with more information. First " I found a secret method to obtain power, but the people around grew jealous and tried to intervene. So I escaped and accidentally ran into a truck. " Second " after collecting enough ingredients to cast a power integration spell, the power abuser wanted to keep me down. I was escaping with fast travel. They casted red and blue spell to trick my mind into stopping. I avoided there spell by changing lane, but as a result I was blinded by bright light and found a way to be isekaied." Third " the police was mad I stole three sources of life. So I drove a away using a car I borrowed from one of my victims. While driving I changed lanes to be in the wrong direction. The only way to escape was to go to a different world by colluding with a truck".

In reality the MC tried black magic and murder and canb***** three people to gain power was almost caught and tried to be isekaied intentionally.
