Isekai ni Tensei Shitara Zenra ni Sareta

Yoshida Shuta is a 31-year-old freelancer that dropped out of college without a clear goal in life. One night, while he's out drinking and partying, he gets teleported into another world completely naked. This world, however, is nothing like our own; filled with magical creatures, dangerous monsters and, best of all, cute girls! Of course, it doesn't take very long for him to get into trouble and be overwhelmed by the circumstances around him. Can he put his various skills to good use and make something of himself this time around?
