弥刀 凉佑

A salaryman who dragged himself along the bottom of a collapsing Japanese society until he managed to get himself run over by a truck.  Upon dying, he is informed that he wasn't supposed to die yet, and he gets offered a chance to go back to before he made a certain choice that had the potential to alter his future.  

His personality is cautious to the point of cowardice, and he retains all his experiences as an ***** in his new life.  However, since he wasn't interested in the world around him in life beyond avoiding trouble, he doesn't remember anything that might be useful to him.
