The Mysterious Heiress: Researcher In Disguise - Chapter 387: Ye Jiu VS Lu Yumo

Broken-hearted and drunk, Yoshida, a 26-years old salaryman, stumbled upon a runaway-from-home high-schooler on his way back from the bar.

“Hey, you. JK.”*

“What the heck are you doing out here. Go home already.”

“Uncle, let me stay at your place for the night.”

“You can do ‘that’ to me if you let me stay.”

“If you meant that as a joke, it’s not funny.”

“I’m not joking. It’s fine by me.”

“Then allow me to tell you that I have no interest in brats.”

“Hmm?”

“Then, just let me stay.”

Notes:

[*] JK is slang for Joushikousei (high school girl)

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.

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.

The ordinary world is not ordinary, ordinary people are not ordinary, and safe places are not safe.

This is a story of a passer-by male protagonist who is entangled by various girls with strange hobbies or even non-human beings while surviving in the cracks and opening a harem.
