It turns out that my Yandere playmate online is my Homeroom Teacher - Chapter 21: Stay away from Haru!

The young man living in a frontier mining village, Elliott, lived in estrangement there.

The reason was because he carried the blood of the Demon Race, and had an unusual face, with two small horns growing from it.

Several years after his mother – his only family – died, a young woman who called herself an acquaintance of her mother’s came to visit, and once she knew of Elliott’s existence, displayed the traits of a succubus, and whispered thus:

“From now on you will ravish many women, steal many lives, and trample over the world, you shall dominate. But to start … you will dominate me, violate me, please”.

Unable to wield a sword, nor kill his opponents with magic, the mixed-blood young man who could only grant a slight bit of magic into matter, used information, tools, and traps, repelling enemies, ravishing women, making them submit and fall into demonhood, and dominated them, surviving in a ruined world.

This is the story of the young man who was the Lord of the perilous place of fear, one that never allows a guest to leave, the “Man-Eating Dungeon”, and the women whose lives had been derailed by him.

“Block him.”“He's technically still my boss.”“Then block him with dignity.”The call ended again.And then started again.I let out a sound somewhere between a growl and a sob, then finally answered with the enthusiasm of a snail crawling through salt.“Yes, Mr. Walton?”“Have you changed your mind yet?”I collapsed onto the towel and gazed at the sky as though it might consume me entirely if I pleaded sweetly enough.“Do you ever take a break?” I asked, shielding my eyes with one hand.“You're avoiding the question.”“Because it's a dumb question.”He exhaled, the sound sharp and irritated even over phone. “It's not a dumb question. It's a business offer.”“It's a weird offer-one that I already said no to.”There was a brief pause, and I could practically hear him clenching his jaw through the speaker.“You are acting unreasonably.”“ Unreasonable?” I sat up. “I'm not the one drafting fake girlfriend contracts like it's a normal Tuesday.”“Isabella-”“Certainly not, Mr. Walton.” I mimicked his tone perfectly. “I told you I'm not doing it. You need to find someone else to play pretend with.”SYNOPSISIsabella Miller thought saying no to her boss’s fake dating offer was the end of the story.But Adrien Walton doesn’t take no—especially not when he’s convinced she’s a gold digger.Suddenly, her student loans are piling up, her father’s vet clinic is on the brink of eviction and her brother is about to be kicked out of college. Coincidence? She thinks not.Adrien Walton is calm, calculating—and he's just pulled every string to corner Isabella into the perfect position.Now she’s stuck choosing between pride and survival.So she agrees to his offer: be his fake girlfriend.No feelings attached. No drama. Just business.Or so she thought.“Conference Room B. Fifteen minutes,” he said, passing by without a glance.The folder he pushed across the table landed with a thud.I opened it. The contract. All of it.---Enemies to lovers? Check.Slow burn? Hmmnyea.Banter so sharp it might file your nails? Yes.Delicious workplace tension? Of course.Tension that could melt steel?Absolutely.Smut?? Wanna find out?Welcome to corporate romance warfare. There’s no escaping this contract.

In this world, orphans or just anyone without any hope for this world can apply to become a “walking target”. Their sole purpose is to be a practicing dummy for the students of the sect who train to become “Demon Hunters”. These students need “walking targets” to test their training on living, walking beings of flesh and blood.
In exchange, they will be provided with food & shelter.
Their existence value is lower than a slave, but if they manage to survive a few years they can receive a life long pension.

Xiao Han is such a “walking target”. One time he witnessed a powerful Demon Hunter disposing a demon. When the demon died, a fragment of the demon that managed to escape entered Xiao Han’s heart. No one saw that, and even Xiao Han himself only felt some discomfort for an instant.

But that thing in his heart soon gave Xiao Han visions, and the first one is of a cultivation method which allows Xiao Han to absorb damage to enhance his body. A perfect cultivation method for a “walking target”.
