Getting Isekai'd to another world is indeed awesome, especially embarking on an adventure as a hero to defeat the Demon King, who turns out to be a woman, and making her part of your harem. It is truly the dream of millions of people hoping to be Isekai'd to another world. If Reinhard were to get Isekai'd like that, he might smile for the rest of his life. However, fate has other plans for him, as he becomes the unfortunate isekai victim, landing in the rabbit hole known as the moonlit world. With numerous psychopaths roaming around to fulfill their dreams, he must strive to defend his small life in this chaotic world, especially when the world is set to last only another decade. Fortunately, luck from nine generations of his family comes to his aid in critical moments. Finally, he gets help to secure his small life: [Ding!] "Eh? Has my help finally arrived?" [Congratulations, Host! You have been chosen as the host of the Antagonist Simulator System!] "Finally! Fina-... wait... What do you mean by Antagonist? Shouldn't it just be a Simulator without an Antagonist?" [As the name suggests, the Antagonist Simulator System is specifically designed for individuals with high aspirations to become antagonists, and you have been selected to be the Ultimate Antagonist! Congratulations, Host!] "Huh? Ultimate Antagonist? Wtf? How does someone as gentle as me fit as the ultimate antagonist?" [Not so.] [Host, you undoubtedly possess a strong motivation, clear plans, firm will, undisclosed secrets, outstanding execution, remarkable personality charm, and the determination to subvert the world.] [Undoubtedly, you are the perfect candidate for the ultimate antagonist.] WTF?

She was just a tired grade school teacher in the modern world- unappreciated, overworked, and denied her promotion year after year. Her only escape was her favorite otome game... until a tragic accident with a banana peel ended her life. When she opened her eyes again, she wasn't in her small apartment anymore. She was in a luxurious mansion. In a child's body. The villainess of her favorite game. Born as the real daughter of a Marquis, she knew how her story was supposed to end: starvation, betrayal, poison, and death. Her stepmother and stepsister would steal everything from her, and her own father would let her die without a tear. But this time, she refuses to play the role of a doomed villainess. Armed with memories from her past life, loyal brothers at her side, and a sharp tongue sharpened by years of teaching, she'll rewrite fate itself. Yet the world of nobility is more dangerous than she imagined- scheming crown princes, false heroines, poisonous stepmothers, and a cold northern Duke whispered to be a beast. But what if the "beast" turns out to be the one man who sees her for who she truly is?
