I Faked a Diary, and the Big Shots Fell for It

[Upcoming Story: A Fox Spirit's Guide to Cultivation] After cultivating for a thousand years, Shen Yishuang finally took human form, but her tribulation failed at the last moment. Luckily, she promptly bound herself to a wild System, allowing her to enter another world and heal her injuries. Putting on airs, sowing discord, stopping at nothing, playing with people's feelings, beguiling hearts, and coveting vanity: these are all basic skills for a fox demon. She has no fine virtues or noble principles, only ruthless methods and wicked thoughts. She isn't kind or upright, but she is peerlessly beautiful, and naturally there are great scholars ready to argue her case. Shen Yishuang says, what could she possibly be guilty of? She just wants to give the handsome young men a home~~ [Story Synopsis] Roy transmigrated into a crossover anime world and became one of the Saint Seiya trainee Saints about to be sent to Sanctuary. He thought he was as good as dead, but then he awakened a diary-forging System. Roy: "...Who in their right mind keeps a diary?" What? There are rewards? And people can see what's inside? Roy: "…Good thing I'm not in my right mind :)" If people are going to read it anyway, why record his daily life honestly? Of course he should make things up~~ And so, the big shots were left completely flustered: First Generation Mist Guardian: "Is the diary's owner reborn?" FBI Ace: "What's a White Album?" King of the Sheep: "I've been hit with Kotoamatsukami, and now some pervert ATM will own me for life?" Fifth Division Captain: "...Teacher Aizen? Heh, what a fine student I've taken in!" Fake Pope: "Nonsense! He's my disciple!" Prince of the Western Country: "My past is your future? Interesting~~" Heavenly Restriction: "Demons and gods will invade in the future, throwing the human world into chaos. Japan will be the first to fall???" Reading Guide: 1. At the beginning, the protagonist doesn't know who has a copy of the diary, so he has to investigate for himself. 2. The diary isn't entirely true. The protagonist makes things up for his own benefit. 3. The diary's rules are made up by the protagonist and are not binding. 4. Includes original settings. Theme: Man can triumph over fate
