The Older Brother of My Student is My Secret Crush - Chapter 164: Outside: The Finale.

In his old world, Elric had nothing—no powerful family, no elite degree, just relentless hard work and a passion for healing. Dismissed as a third-rate doctor, he shocked the nation by saving a congressman’s life and becoming an overnight celebrity. But just when his career was rising, tragedy struck.Now, Elric opens his eyes in a world unlike any he’s ever known—a land of swords, sorcery, and strange beliefs. Reborn in the countryside of a magical kingdom, where even a common cold is blamed on spirits, he’s the only one who understands how the human body truly works.With no palace, no power, and no one to trust, Elric sets up a humble clinic in a rural village. Armed with science and sarcasm, he treats the sick, challenges ancient traditions, and slowly earns the awe and fear of a world ruled by magic.Mocked as a fraud. Hunted by rival healers. Feared by nobles and mages alike.But this world is about to learn—Even a third-rate doctor can change history.

This story revolves around a boy who was sent to a dark, mysterious parallel world in the body of his beautiful senior sister known as Lily. The lone girl ran into the night parade of a hundred ghosts the very day she arrived; seeking survival amongst the warrior’s dispute in a chaotic world, and forging her own demon sword! This is an unimaginable other world adventure!

There are a total of seven sins, and a revelation is made to a young man named Alex that he is destined to become a demon lord, more especially a demon lord of sin called LUST.

It's not like he can change that and because he always knew something about himself was different—not in a physical sense, well, maybe a little—and not in a mental sense—but rather because he is thrown into a demonic war that compels him to accept his new reality.

He was only aware of a difference in himself. Relating to him and the ladies who are drawn to him... Well, it was more or less like he was a magnet in front of all the girls, and all the girls were drawn to him like a metal.

Severin Reignhart was just an ordinary gamer—until a truck accident sent him into the world of Legacy of Heroes, a novel he had once read.But instead of becoming the protagonist or even a powerful villain, he finds himself reborn as a complete nobody. An extra with no screen time, no future, and worst of all… no real strength.His so-called Talent Ability—Command—doesn’t make him stronger. Instead, it grants a 300% boost to the abilities of those who are bound to him and follow his orders. A powerful buff, but utterly useless when he is weaker than even the lowest-ranked students at Zenith Hero Academy.Thrown into a world where strength is the only law, Severin quickly learns that if he can’t fight, he’ll be crushed. Refusing to accept the fate of an extra, he turns to manipulation, deception, and blackmail, using his intelligence to twist the battlefield in his favor. If he can’t be the strongest, he’ll control the strongest.With the looming threat of world-ending catastrophes and prodigious heroes destined to take center stage, Severin must navigate the deadly hierarchy of the academy. He will recruit, betray, and outwit both heroes and villains—because in a world where power is everything, strategy is his only weapon.And one thing is certain: he refuses to die a nameless extra.
