Reborn as Rimuru: I'm too OP

So I died. Not surprising given the fact I was hit by a truck going full speed. What WAS surprising, however, was the fact that I got to meet a ROB and got three wishes... Is what I'd like to say, however, since (s)he was omniscient, it wasn't so much of getting three wishes as it was them shoving me out of the door quickly after reading what I would have asked for. Oh well, at least I got to be reincarnated as my favorite protagonist in my favorite anime world with a power to make me so OP that I'm basically speedrunning the ranking of power in the world. I created this fanfic because I was bored and reading another Tensura fanfic which gave me inspiration. The MC is going to be a nice guy and I'm going to be stealing ideas from my other fanfics a lot so fair warning. Also, despite this being a harem fic, the MC isn't going to be going after other people's women, or chucking others. He is even going to encourage relationships between his subordinates. If you don't like that, then don't read.
