This series is a funny little one by the same author as Surviving in another world with Goshujinsama (not to my taste, as the protag is M and a bit of a hetare, but it is really popular in Japan).  The protagonist of this story is randomly transported to another world by a mischievous evil god (Pretty sure her/his real name starts with Nyarl, like most evil gods of this type in otaku stories) and left to his own devices.  Taking advantage of his high growth rate and ability to pick skills to grow (something the natives don't have), he tries to live freely... but life isn't going to let him be.  Before he knows it, he ends up drugged and in bed with an aggressive but incompetent adventurer girl named Marl, and soon after, the country takes interest in him.

Generally speaking, this story is basically a power trip where the protagonist plays hero for a while before ending up as the lord of his own territory with a harem of women who control his life for the most part.  It is funny, fun to read, and while the protagonist does struggle at key points, when it comes down to it it remains a power trip to the last.  There are a few points in the story that would probably sicken people who don't like barbaric behavior (one particular incident in the first part), and some people won't like the way the women take over his life.  However, I found it an amusing story, and it has the advantage of being complete and available on Shousetsuka ni Narou for free.

Oh and the protagonist has a really wide strike zone, lol.
