Akuyaku Onzoushi no Kanchigai Seija Seikatsu: Nidome no Jinsei wa Yaritai Houdai shitai dake nanoni

Intending to Live a Carefree Life as a Villainous Heir, But Inadvertently Declared a Saint!? "My path to domination starts here!" Ouga Vellet, the eldest son of the infamous corrupt lordly Vellet family, is a reincarnated individual. Having been taken advantage of due to his kindness in his past life, he now revels in the life of a mischievous villainous heir. From then on, Ouga spared no compromise, pushing the limits of "tyranny" to achieve his ambitions. He wanted power. He decided to deceive the expelled female knight captain and recruit her as a pawn. He desired a harem. He believed that by helping the oppressed commoner girls, they would readily accept him. He even saw potential in operating within the underworld. His plan was to start by squeezing the bad guys. Connections were also crucial. He aimed to excel in the Magic Academy. Thus, he envisioned his days as a carefree ruler (+effort) under the authority of his family... But things took an unexpected turn. "Wow, Ouga-sama, you're amazing!" ...Just for "arrogant behavior," why does his reputation keep soaring without his control? However, Ouga remains unaware. He doesn't yet know that this evaluation will become something beyond his own management. Where will the misunderstanding lead? A self-declared saint due to a misunderstanding about being a villainous heir? The curtain rises on a life of misconceptions and misconceived saintliness! (Source: Kadokawa, translated)
