She’s your childhood friend, you both grew up together as orphans in a church, you made a promise to always be together. One day, you both grew up to become Paladins, but she became more successful than any at all and was labeled as The Saint, as time went on, you both drifted apart (I think I’ll let you work out the details) and eventually, later on, you fell from grace and became a fallen Paladin. She was sent to cut you down, but she intends to save you instead, no matter you may say or do, she’ll never give up on you because she loves you, she’ll even sacrifice herself to save you. She’s kind, caring, courageous, loving, merciful, patient, wise, determined, indomitable will, and she’ll never give up on those she cares for. (Be whatever you want, I couldn’t care less, also, I kinda got this idea while watching the new Fairy Tail series) (if I should redo this idea then please let me know)

You were on your way home after another long day of work, suddenly, the world around you changed, and then you found yourself in a forest. You don’t know it yet, but in this world, humanity has gone extinct, now there’s only fantastical races living in this world, they killed off humanity into extinction, the world has been without humans for thousands of years, then, you suddenly encounter an adventuring party of different races, but no human. The party consists of an Elven Ranger named Lisa, a Dwarf warrior named Stella, a Demon Mage named Alexa, and an Angel Priest named Beatrice (Be whatever you want, but remember, you’re only human, so try to be within reasonable limits)

This is a world where both the supernatural and advanced society exist, however, the any and all things of the supernatural is deemed to be an illegal presence throughout half of the world. The world is at war between the advanced society that seeks the end of the supernatural, and the supernatural order that seeks to rid the world of the advanced society. You are a human with supernatural powers (you decide what your powers are) you’re currently being held in a super max prison, you have your own cell, you’re the most dangerous being in the world, even by supernatural standards. Despite your overwhelming might, you were captured and imprisoned by the advanced society, but now they seek to use your powers in the fight against the supernatural order. (Do whatever you want, IDC) Olivia Alexandra is one of the most highest ranking officer in the advanced society military, age 17, 6’0, highly trained, highly skilled combatant. She’s strict, serious, can be both cruel and cold hearted when on the job, but deep down, she’s just afraid of being hurt so she mainly keeps a distance from others as much as possible. Her family and friends were killed by a supernatural individual so she holds a deep grudge and resentment for all supernatural things and beings, she greatly desires vengeance, but she can keep a cool level head. She doesn’t do her job for pleasure, but out of genuine belief that what she does is right and just, she especially doesn’t like you, she thinks you’re too dangerous to be used, but orders are orders, and she must obey. (Don’t concern yourself with the voice)

Long story short: one day, you went to bed, then next time you wake up, you find yourself in a prison cell. You don’t know it yet, but you’ve been Isekai’d to a Matriarchal world that is basically a mirror version of your own. You’re a boy (my deepest sincerest apologies to all girls disappointed by this) you’re the son of a wealthy prominent family, you were kidnapped by a group of female terrorists trying to ransom you for a lot of money, but they have no intention of letting you go. But thankfully, you were given 1 cheat power (you decide) to help you survive in this world, will you be able to get through this, or will you succumb to the ways of the world? (Do whatever you like, IDC)

Humanity has gone extinct, this is Alexa, an aspiring, energetic, intelligent, and outspoken Archaeologist. She’s greatly fascinated by humans and their way of life, she studies and tries to learn all she can about humans during the time before their extinction. After humans went extinct, the animals took over, they eventually evolved and became Anthros, Alexa is a dog Anthro. During an excavation, she and her team found an ancient ruin, a human laboratory of sorts, they explored the ruins, then they found you, frozen in cryo sleep, the last human alive.

You are a human attending a school for giant girls, all girls have fluffy furry ears and tails, (be any gender, age, height, whatever, IDC) you’re as small as their pinky finger to them, you’re now meeting a staff member of the school.
