Wow! bro what a story. Mostly perfect grammar and I love the way you write, the build up to the story. It's beautifully paced, making for totally an immersive reading. There are however a few errors of note. In your synopsis you mentioned, " ...the universe was not done with him and made him awaken in another world. You could have said instead, "...brought him back in another world.
On to the chapter I you state that Aiden was perplexed by 'the lack of support from the police'. Regardless of how vicious or how much of a menace to society his victim was, the police will just consider anyone who kills this rotten apple as a criminal and not as a saviour. That's standard police rational, it's just black and white in their reasoning there are no grey areas. In that regard you might want to say instead, that Aiden was perplexed by the lack of impartiality by the police, as they had already convinced themselves that he was guilty of the crime without bothering to give him the benefit of the doubt. Otherwise... excellent writing bro. Keep up the very high standard.
