Survival In A New Fantasy World

Takashi wakes up in a world nearly devoid of people, with no personal memories and in a world full of dangers.
From zombies and skeletons to sea serpents and dragons, all wanting him for breakfast, how will he survive in a world stuffed full of so many dangerous monsters?

But Luck may be on his side!
He may not remember much about who he is but, surprisingly, not only is his head is full of knowledge, he also has a game like interface that pops up in front of him! He just has to find ways to put it all to use, and that he does.

-------------------------------
May or May not have romance and or harem, idk yet but if it does than you can expect some R18 chapters. (I have never written any before so they might not be that good)

Author Note:: This novel is going to put out chapters whenever I feel like it, the average chapter length will tend to be around 3k words.

Author Note 2: I am NOT dropping my other novels, just working on this as I try to edit and figure out what I want to do with the others.
