Reincarnation Gone Unplanned

Steve (yes that's what we're calling him) was minding his business, as you do, then he decided to take a nap, and woke up with a god in front of him.

Apparently someone bombed his town while he was sleeping and now he's there, the god explained "You have a personality and a moral system unlike most, I'd deem you a proper equalitist, for that I would like to reincarnate you, with your permission of course."

Wanting another chance he said yes, he was offered either to choose what his abilities are or let the god decide and he can take a companion with him, he chose his companion cat named Fuzz and he was reincarnated... But with Sonic.exe's abilities.

Now center of an unfamiliar anime with powers he doesn't know and a mission to be a good guy with dark abilities, his trusty cat by his side and a belief things wont be bad or dangerous compared to his former situation (but also not believing that) he sets out on his journey.

Its a shame that god wants to give him a harem considering he doesn't have a love interest and the intensity of Dark Matter Sonic.exe uses doesn't make it easier.
