The Invincible Full-Moon System - Chapter 15 Rosie’s Deal

After being torn from the only life she knew, 16-year-old Margo is forced into a new home with strangers who call themselves her parents. Haunted by memories of her past and consumed by feelings of isolation, she struggles to adapt to her unfamiliar surroundings. School offers little relief—until she meets Lucien, a mysterious boy who appears just when she needs a friend the most.Gabriel is everything Margo needs: kind, attentive, and always ready to whisk her away from her troubles. Each night, he invites her to secret places—an abandoned playground, a fog-choked garden, a crumbling train station at the edge of town—each more unsettling than the last. Yet with every chilling rendezvous, Margo feels more alive... more seen.But something isn’t right. Gabriel never comes to school during the day. Her adoptive parents never see him. And when they catch her talking to thin air, their concern deepens into fear. They say Gabriel isn't real—that he’s a figment of her imagination. Margo wants to believe them, but Gabriel feels real. More real than anything else in her life.As the nights grow colder and more twisted, Gabriel’s true nature begins to surface. Shadows move where they shouldn’t. Time warps in his presence. And the places they visit seem to echo with whispers from another world. Margo is forced to ask herself: Who—or what—is Gabriel? Why does he only want her? And what will happen on the final night he asks her to come with him?As the line between reality and delusion begins to crumble, Margo must make an impossible choice: stay in a world where she feels loved, or return to one that barely feels real.But one thing is certain—some friendships never let go.

Fear breaks the boundaries between dreams and reality, and it is impossible to tell which is reality and which is illusory. When the nightmare really comes, no one can be alone.

This is both a danger and an opportunity.

On Christmas day, seemingly overnight, God summoned everyone on Earth, giving every single person a 'Gift' along with a System.

These Gifts, synonimous with special abilities granted people powers beyond comprehension.

However, with these abilities came tragedy that enveloped the world. The Apocalypse!

Jeremy Lewis, a reclusive loner, is mysteriously exempt from this phenomenon and finds himself being the only one without a Gift.

God decides to grant him the last Gift available, [Subspace], and forcefully returns him to a world that has become hell.

Horrifying monsters now lurk around every corner, and inevitable death awaits.

Arming himself with his wits and the Gift he possesses, how will Jeremy survive this cruel new world that he finds himself in?

“Everything will go according to plan, and ultimately the path I have started will lead to my victory... these tools will be useful in achieving that!”

“Teacher, you know me. I’m usually a good student, with nearly 100% attendance, and I’m also eager to help the people.

Yesterday I flew to the coast to fight monsters, so…”

“Teacher, you know me. Which teacher is not full of praise for me, but things are prioritized. Yesterday happened to be the Ghost Festival. Hundreds of ghosts walk at night, so I…”

“Teacher, you know me well. I am an activist in our dormitory. Every day I call them to go to class, but under special circumstances, so…”

“Teacher, I’m a foreigner, I don’t understand what Xie said, and I didn’t know there was a class yesterday, so…”

The teacher took off his glasses and rubbed his temples, “I can tell that everyone in your dormitory has stunts, but this is by no means a reason to skip class! This class! This year! You guys are all done!”
