I, the Messenger of the Demon King, Am Not Evil, I Just Want to Save Money to Redeem Myself.

The Demon King's Castle has been lost! The weakest Demon King team in history finally realized that the most promising path was to give in to the Adventurer's Guild and ask for cooperation, launch the "Havoc in Demon King's City" experience project, continue to act as a crusade target for those who are interested in conquering Demon King's Castle, and share the project profits! ... Wait a minute, what does "The guild has announced the values ​​of the Demon King's team, and to be fair, we brave men don't bother to take action against you weaklings"? ! Lord Demon King: "It seems that there is a problem with our business model, and we must introduce new variables to empower this 'Havoc in Demon King City' project." "It's time to summon an unlucky messenger and let him be used by us, Jie Jie!" So is this the reason why I, Sears, came to another world and had to help the Demon King earn 10 million gold coins before I could return to reality? All the colleagues were ruined, and no one came to sign up for the brave, so he had to issue the task request himself and play the role of the target of the crusade. The helpers are——the upright brave man who is absolutely single-minded and the otaku princess who is absolutely fun-loving? ! A human-machine system full of AI, constantly adding deadly skills, a lucky beast that earns a gold every day, a persevering pursuer - wait, this is not life-threatening, right? I, the messenger of the Demon King, am not evil, I just want to save money to redeem myself! [Fun impact]+[nonsensical]+[Abstract text]
