System: My Idol Training System for Hoshino Ai

Saito Hiko, a reincarnated fan, knew Hoshino Ai’s tragic future: a lonely life, betrayed by love, ending in a brutal death. Reborn 20 years before the original story, he watched the innocent 12-year-old idol-to-be walk unknowingly towards her demise. He vowed to change it. A \"Star Training System\" awakens, offering him everything: a constant stream of hit songs, an \"Idol Training Aura\" to unlock her true potential, and resources to build an empire. His mission: elevate Hoshino Ai to unimaginable stardom, shielding her from every shadow. But the true mastermind behind her original fate still lurks, a hidden enemy far more cunning and ruthless than any fan. Can a 12-year-old boy, armed with a system, truly rewrite the destiny of the brightest star?
