Akuyaku no Goreisoku no Dounika shitai Nichijou

Synopsis:

The beloved third son of a powerful ducal family is determined to escape his villainous fate. At just six years old, a once-spoiled noble suddenly regains memories of his past life—only to realize he’s been reincarnated into an RPG world. Worse, he’s destined to become the weakest of three brothers and ultimately be defeated by the hero as a doomed villain. After panicking, sulking, and overthinking his miserable luck, he reaches one clear conclusion: quit being a villain. To survive, he’ll become a well-behaved good boy, strengthen his bonds with his doting older brothers and loyal servants, and avoid every possible death flag at all costs.
