Villains.Characters who opposed the protagonist.There are charming villains, there are villains with a touching backstory, there are villains who are simply pure evil, there are villains you can sympathise, and there are villains who simply have that title because they aren't on the same side as the protagonist.But no matter what kind of villain you are, at the end of the day, you are just a stepping stone for a protagonist.But in this vast universe, where immortals can pluck the stars and gods can create the sun, there are villains who won't stand for their fate.They will trample over the protagonist and defy their predestined fates and declare to the heavens,“Villains aren't stepping stones!”

The Solvaris Empire is surrounded by the Godspire — a massive wall a thousand meters high, older than anyone can remember, and deadly to cross. No one knows if it was built to protect the Empire… or to trap it.Reth, a 19-year-old from Earth, finds himself in this strange world. He has no great strength or magic, but a unique Obedience System forces him to serve Princess Asthia, the sharp and ruthless commander of the Serpent Wing.If he disobeys her, he suffers unbearable pain — maybe even death. If he obeys, he gains new powers and skills, growing stronger with every command.While the Empire’s Obedience Sigils keep its people in chains, Reth’s System makes him something different — a weapon, and Asthia’s personal bodyguard.Together, they face plotting nobles, rebel cults dreaming of life beyond the wall, and monsters twisted by corrupted mana.But as Reth’s Corrupted Intent — a cold, unshakable will — grows, so does his resistance to Asthia’s control. Their uneasy trust is tested when they uncover a secret about the Godspire’s true purpose.To protect Asthia and reveal the truth, Reth must decide whether to keep obeying… or risk awakening a horror that could destroy them both.

A young man with an extraordinary mind is off on an exciting adventure when he mysteriously wakes up in the body of a feeble slave-guy in a different, rich in quirks world.

The main character, a selfish jerk, would use extreme means to achieve his goals. However, he never allows his base instincts to overrule his sense of decency. He always pays back both good and bad deeds.

Will his (terrible/excellent) mentality help him make a fresh start? Will he get through misfortunes and hardships of the new world?
