Arifureta Shokugyou de SekaI Saikyou for better or worse is a story that fails to live up to the quality and potential it displayed in the first volume. The premise and concept that were seen in the first volume actually made it seem different from the various "transported to another world" light novels that have recently plagued the market as of late.
The first volume presents us a story about a boy who had been betrayed and left for dead. A boy who's very essence of his humanity was destroyed. He drastically changes in order to survive the extreme dangers that he faces around his environment. So far the premise of the story sounds good, and the potential that we'll see a dark story filled with psychological conflicts of his humanity all seem to be in place, but nope that's as far as this story goes. The first volume ends with him being introduced to the first heroine of his official harem...
And that's where the story completely goes down the drain and as if the author waged his tail at the sign of $$$ the author decided to completely ruin his own story by falling back into typical, generic tropes that all other similar light novels have.
It becomes another edgy, angst, cliche, harem story where the MC consistently complains and has awkward moments with his harem. The girls themselves aren't anything special and they fall to the typical tropes of a loli, oppai, demi-human, etc. They add nothing to the story other than to emphasis how great the MC is. The other characters in the story are completely useless and are only added to the story to help support the idea that the MC is amazing. From the second volume and on nothing ever really threatens the MC because he can easily overpower them with his deus ex machina that the author will consistently write in the story just for the sake of it. The story becomes just another hot pile of garbage that lacks any sort of creativity or anything to make it stand out out from the ever-growing saturation of reincarnation stories.

Btw, this novel is completely translated and can be read at bakapervert or some other random wordpress blogsite. Don't waste your time though, the story never gets better.
Read the first volume and then proceed to drop this harder than the bass at a night club.
