Before the tale of the rabbit-hearted hero began-before Bell Cranel ever set foot in the Dungeon-there was another age. A time when legends still walked the streets of Orario, when the banners of Zeus and Hera fluttered proudly above all others. This... is the story of the Golden Era. At the heart of it all stands a boy named Amatsuki Haruto, a reincarnated soul with dreams no grander than a peaceful life-and yet fate, in its twisted sense of humor, decided otherwise. Armed with nothing but questionable common sense, half-baked skills, and trauma from "training" under his terrifyingly beautiful (and possibly ogre-blooded) master, Haruto is forced-yes, forced-to march toward the City of Heroes. His teacher's words still echo in his ears: "If you don't go, I'll beat your ass so hard you'll respawn in Tenkai." Thus, leaving behind his beloved little sister (and whatever remained of his dignity), Haruto begins his reluctant adventure. What awaits him is not peace, but chaos-where gods play dice with mortal fate, monsters crawl in endless darkness, and friendships are forged in shitty familia. And so begins the untold legend of the boy who would stumble, scream, and somehow survive amidst the gods- The story of Amatsuki Haruto, and the dawn of the Golden Era.

He... was a talented young man who always had a passion for music. Despite his jaded emotions, he worked relentlessly to improve his skill in the hopes of one day rising to the top of the music industry as a dream. But all of his efforts were futile because his upbringing, and even his own mother, pushed him to end his life... with his own hands... But in a strange twist of fate, he is reincarnated into the child of the one person who made him feel joy, Hoshino Ai. Given a new name, Hoshino Alexandrite, and a new life, he swears to pursue real happiness and help Ai's idol days shine even brighter with his musical talents. That was until Ai was tragically murdered... breaking him... But despite it, he cannot ignore that he was given another chance to right his wrongs, to live the life he never lived before. With the support of his new siblings and a dream he never thought possible, he will not falter again. Broken as he is, as a scum he may never change, but he promises his new mother to live the life she wanted him to live... but the thought of vengeance for Ai's murder never left his mind... Will he live to fulfill his promise? Will he find a path that takes him to the life he so wanted? Or will he succumb to the pressure of the music world as he encounters trials, scandals, decisions, and a bewildering emotion spurred by two girls, one who wants to save him from falling deep into his darkness, and the other who wants to make him accept who he really is and live unshackled? Will he shine just like his mother, or will he collapse and become The Dark Star? 【This book is written as a person challenge and a dedication to one of my favorite mangaka, Yokoyari Mengo!】 【This book will borrow some lines from the original source material (manga) to not stray from the story too much and for familiarity】 【Oshi no Ko respectfully belongs to Aka Akasaka and Yokoyari Mengo respectively】

Ai Hoshino had to admit that concerts were becoming more demanding as they gained popularity. Perhaps something sweet could cheer her up after an exhausting concert, or maybe it's just an excuse to see the sexy blond barista who works at the shop.

Una noche, Bell Cranel simplemente fue a dormir... y despertó en un Orario que no reconoce. La Torre de Babel sigue en pie, pero su hogar, su familia, sus amigos... han desaparecido sin dejar rastro. Nadie conoce a Hestia. Nadie ha oído hablar de la Familia Loki. Todo parece igual, pero al mismo tiempo, irremediablemente distinto.
