A Protagonist & Player’s Reunion | Yandere Core Frisk

For most of their life, Core knew only the quiet ache of solitude. Orphaned by the ravages of war at only eight years old, they spent weeks wandering the wastes, guided by nothing but the ghost of a promise their mother once made: that one day, they would see the heights of Mt.

They gained everything they once lacked—a family, a home, and the adoration of thousands.

And yet, the hollow ache remained

That void within them stayed empty until the day Core peered into a strange, vibrant new reality—a world shaped
