The Demon Prince goes to the Academy

Here's an improved synopsis, incorporating your requirements: "The Temple, a prestigious academy dedicated to shaping the future elite of the empire, boasts a Royal Class – a haven for students distinguished by their exceptional talents. In the wake of humanity's decisive victory in a protracted war against demons, a new generation of warriors rises, led by the earnest but somewhat naive Ludwig. This is the world of 'The Demon King is Dead,' a web novel destined for incompleteness. Its 30-year-old author, burdened by scathing online criticism, finds himself abruptly reincarnated into its perilous reality. He's no longer a writer, but the Demon King's 17-year-old son – a frail figure marked for an early demise. Armed with the grim knowledge of his fate, he immediately deviates from the original plot. Enlisting the aid of his demonic kin, he forges a new identity: Reinhart, a blonde-haired human boy blessed with an extraordinary power. Under this guise, he enrolls in the Royal Class – a crucible where heroes and villains alike hone their skills. His mission: to survive, to learn, to master his abilities, and ultimately, to guide the story to its true ending. His transmigration wasn't accidental. After dying from the shock of reading hate comments, a Grim Reaper appeared, deeming his poor writing a sin. To earn redemption and ascend to heaven, he must navigate the treacherous landscape of his own unfinished novel and survive beyond its predetermined conclusion. "Damn it all!! Why did this have to happen to me?!" He laments. He is the Demon Prince, a character doomed to die at the start with zero combat ability.
