That time I was reincarnated as Rimuru too

You know the usual isekai bulshit, this is the same..A wish fulfillment.
*
A guy die by the hand of a ROB, who mistakenly killed him thinking of another. So, the Rob give him a choice for reincarnation. So, the guy choose to be Rimuru. Was it a right decision or wrong? Was it a heaven or hell? It's remain to be seen.

Personally? I don't think anybody can replace Rimuru Tempest. Mikami Satoru, became Rimuru because of his character. So, I don't know where this story would go.
___

Make some magic beasts that can be found in Tensura and their skill. I didn't find many.
List some skill as well. I'll make a auxiliary chapter for it.
Remind me if I made a mistake, but don't be too harsh..ok? Thank you.

I started writing this story after reading first chapter of “That time I got reincarnated as Rimuru Tempest” fan-fic. Read it if you can, I don't know if it's good or bad. I don't want to criticize others.
Ok then, Happy Reading.
