Haruko could hardly believe it — she had actually transmigrated into a melodramatic female-oriented novel. And she had become a cannon fodder villainess! Facing a death flag right at the start, Haruko decisively transformed into a yandere loli and confessed to the female lead. “Ichiko, the one I like is you!” “You clearly said you liked me — so why are you still going to someone else!” “I won’t allow you to like anyone else. You can only like me!!!” She would confess, make her fall in love, and then fake her death in front of her — making herself her one and only. But gradually, Haruko noticed something was off. The female lead seemed to have been raised into a yandere. “Hey, Haruko, you can only like me too, okay?”

"Although I was reborn as the weakest of the five-colored dragons, and transmigrated into a little female dragon, and had a disastrous start, at least I am a top-tier race. It's better than being reborn as a maggot, right?" Jona Velli looked at the pure white dragon scales covered by blood and dust, and was forced to accept the fact that she had inexplicably transmigrated to this magical continent and become a little female dragon because of drinking. "Now that I've come to this strange world, how can I not make a big splash? Hehehehe..." ………… Seeing the awakened power of time, Jona Velli was so excited that she almost jumped up and started spinning like a Thomas the Tank Engine. Time acceleration? No, no, no, that's not a good description at all. It should be renamed "Weekend". Time has forgotten? No, no, it should be renamed [Breaking Promises], hehehe~

What should I do if I transform into a passerby NPC in the Novice Village who may die at any time? At first, Lily just wanted to survive and increase the player's favorability. She planned to use the power of the players to increase the strength of the NPCs who were not on good terms with her. Unexpectedly, she accidentally increased the favorability. From [the player's most solid backing] to [the lonely watcher at the border], and then to [the first saint in the turbid times of the empire]. Players give full play to their subjective initiative and lift her to the throne. In the 30th millennium of the empire, a former emperor of the empire who did not want to be named loudly accused in an interview with a newspaper. "That group of undead people rushed into the palace shouting friendship and bond, and forcibly put my crown on the head of Lily, the devil. It's really a sin!" Facing the accusation, Lily was extremely indignant. "How can I be a devil? From the beginning to the end, I have been promoting love and justice. Don't talk nonsense with your eyes open... It's hard for me too. Sometimes I look for my own reasons. Have I been a good person for so many years? Why do those undead people only hit you and not me?"

Traveling to a world where ghost stories and abnormal creatures are rampant, Serie not only becomes a beautiful, fragile, and sickly girl like a porcelain doll, but is also taken in by the salvation organization as an S-level abnormal creature and imprisoned in a steel fortress in the deep sea. But Serie didn't care, because she found that as long as she closed her eyes, those witches condensed by fear, desire and power would open their demon eyes on the other side of the world. They were walking taboos and also puppets dancing on Serie's fingertips. Each witch has a completely different form and ability. Complete tasks, light up the skill tree, and continuously upgrade and evolve. Beautiful and powerful S-class witches appeared one after another like mushrooms after rain—— "The Witch of Pleasure plunges New York into a lewd abyss?" "The Dread Devourer ate the Golden Gate Bridge clean?" "The Slaughter Witch rules the battlefield, weaving nightmares for her enemies with threads of blood?" "The ruling witch made the organization's top executives betray her and become her loyal servants?" Alarms on the radio sounded one after another, and the employees were talking about Serie's trumpet, some with fear, some with admiration, and some with vigilance, but they would never know that the culprit of all this was that useless and cute girl who was tied with chains and restraints and did nothing every day except act coquettishly and wait for food. Serie said nothing, just buried her face in the pillow and continued to play the simulation game: "Let's open a new account... I want to try a different evolution path this time."
