Power and a Harem from One Act

When I woke up, I was born into this world as the second son of a duke in another world. This is what they call a reincarnation into another world, with memories of my past life. I can’t remember my name, but in my past life I gave my all as an otaku, but my unhealthy lifestyle took its toll and I died relatively early. Well, I’d be lying if I said I had no regrets, but I lived life the way I wanted to, so I have no regrets. I was born into the duke family of a certain kingdom in another world. Apart from my parents and my worthless brothers who were obsessed with power and lineage, I was born with a talented body, skilled in both the arts and martial arts, and was also blessed with an awakening ability that was my trump card. This is the story of me living my life however I want, and the way I want to do it. Supposed an otaku were reincarnated into another world, they’d just gonna be doing all sorts of things right? That said, I don’t want to die because of carelessness, so I’ll do it with careful steps and caution in mind. I’ll do what I want to do and live out my natural life!
