As a twenty-fourth-tier writer on Green River, he started writing a story full of secret identities to ride the latest trends.
Unfortunately, the market was crowded, so he decided to win by sheer volume!
To grab readers' attention, he turned his protagonist into a 007-style corporate drone, juggling countless secret identities, getting work done and stirring up trouble at the same time. He shoehorned in characters who had nothing to do with each other, and gave every secret identity a tragic, tearjerking backstory.
The author happily counted his royalties while readers cried in the comments. Who even remembered the man behind it all, the real protagonist whose name nobody knew?
Fueled by the resentment of an overworked drone, the shameless author's comeuppance came fast.
He woke up one day transmigrated into the unlucky protagonist, who got no raise, no sleep, and no attention.
...Who the hell wants to be this miserable, split-personality corporate drone?!
He immediately went on strike and quit, determined to retire all his secret identities as quickly as possible and live a carefree life in his own novel!
Wait, why are they looking at him even more strangely now?
The strange ability users who had suddenly appeared in Japan, itching to make trouble, vanished overnight. It was as if they'd all suddenly started slacking off.
The boy who always seemed to run into Gojo Satoru, looking troubled and like he wanted to say something but couldn't, began avoiding him;
The low-level clerk at the Armed Detective Agency dropped his usual gloomy, chuunibyou act. When he handed in his resignation, his one good eye was full of world-weary resignation;
Hell Correspondence, once popular among students, was gone as quickly as it came, and the magical girl who protected lost souls at night became an urban legend...
But when all his secret identities stopped causing trouble, the people they'd once antagonized came after him instead. He had no one to blame but himself, so he could only keep acting through his tears.
"I'm sorry, I don't know you. What...a curse?! Wasn't Menma just a hallucination only I could see?"
"Superpowers aren't a way to cheat, and this world doesn't need miracles. If you can, please just treat me like an ordinary person."
"Human hatred has no end. I'm tired of watching this ugly spectacle."
"Welcome to the Magical Girl Café!"
