[Two male leads, slow-burning Tom x Abraxas]

'The people I love are destined for misfortune, born from aphrodisiacs, despised beings, haunted by the most vicious curses... Even if I were to merely appear in your sight, I would feel as if I were defiling you, who are like a god... Therefore, I do not love you...'

Good people often have short lifespans.

If we're going to do it, let's be a scourge that wreaks havoc on the region!

He traveled to the Harry Potter world and became the last bloodline of the Prince family, a blood relative of Snape!

Alan Prince vowed never to be a good person in his life, but incidentally saved Snape from his tragic fate.

Some people say he's just a child with a bad temper.

Some people say he is a dark demon king who wreaks havoc in the region.

But many more people see him as the salvation of an ordinary wizarding family and a great man who led the magical world forward.

But all Allen wanted to say was that he was just an ordinary wizard, at most with a bad temper.

P.S.: What kind of normal person could a child raised by Snape be?! (Snape: He's slandering me!!!!)

The synopsis is weak, so I'll move the main text. There's a decent Harry Potter fanfiction as a base, so feel free to use it.

Kohler, who lives in a London industrial wasteland, lives with a madwoman who is obsessed with finding magic. Kohler once firmly believed that she was insane.

However, one day, while being chased by a British gentleman, he bumped into a "wall" that turned out to be a bar where everyone was a wizard. It turned out that magic really existed in this world!

But why do they all call him "Harry Potter"?

There was no other way but to pretend to be the savior.

While at Hogwarts, I awakened the Middle-earth Survival System, but something about the system was a bit off… [You received your Hogwarts acceptance letter—Main Quest: The Fellowship of the Ring!] [You didn't go to Gryffindor, but instead joined the Hufflepuffs, a bunch of gluttons—Reward: Hobbit Racial Talents (Stealth + Gluttony)!] [You refused Malfoy's handshake—Reward: Strength +1 (That's how you deal with fallen elves!)] [You wielded your wand powerfully—Reward: Two-handed Sword Strike (Magicians should have some Strength)!] The system actually thought I was in Middle-earth from Lord of the Rings?! …Years later.

"You'd better find something to eat before dark." This was the first thing Kane heard after running away from the Dursleys. Okay, I knew I hadn't completely escaped the Famine world... but thankfully, his ability to manipulate his shadow in Famine still remained, not only saving him from starving to death after running away and being killed by invading shadow creatures at night, but also bringing him other benefits in this world. Wait... what does "for using dark magic in front of Muggles, now granted a VIP status in Azkaban" mean? Dumbledore blushed and quickly snatched the envelope from Kane's hand, replacing it with another. A Hogwarts acceptance letter, this time it's right.

Encountering the Hundred-Ton Queen, Tang Yan, a superpowered individual capable of breaking down objects into raw materials, simultaneously traversed countless worlds. After reuniting in a shared space, he discovered that his superpower could be stacked and strengthened, transforming from the original dismantling into [Return to Origin]: capable of breaking down all things into their essence. From then on, Tang Yan and his companions embarked on a path of resource cultivation. Starting with just two hands, resources were all obtained through plunder. [Harry Potter Tang Yan]: "What Voldemort Horcrux? It's clearly the essence of magic!" [Mr. Zombie Tang Yan]: "The old man was afraid of fire? No problem, I'll dismantle it into spiritual essence and yin-attribute luck." [Under One Person Tang Yan]: "What Quanxing? It's clearly spiritual material!" [Armor Hero Tang Yan]: "This is no ordinary monster, we must strike hard!" [The Boys Tang Yan]: "What superpower...

Docroft Evans, a transmigrator from the Muggle world, finds himself as the older brother of two special sisters: Lily, who possesses amazing magical talent, and Penny, who yearns for magic but cannot have it.

When his Hogwarts acceptance letter arrived, he embarked on his wizarding journey. Unlike in the original story, he met the lonely Severus Snape in his childhood and decided to protect this misunderstood boy in his own way.

That year, the werewolf howled, and he died in the Screaming Shack.

That year, golden energy accompanied by a whooshing sound like rusty gears grinding, the dead returned to the realm of the living.

Revenge? Retaliation? Or forgiveness?

Wizards become Muggles, and Muggles become wizards—should they disappear or merge?

Upon returning to England, he receives an invitation from Hogwarts.
