Black summoner (1-14 volumes of new book)

A man wakes up in a strange place with no memory of where he is or who he is. When I asked the guide, it seems that he, who had obtained the right to reincarnate in another world, acquired a rare skill in exchange for all the memories of his previous life, and was reincarnated as"Summoner Kelvin". What's more, even the goddess of this world, Melfina, is under her control――!?
And adventurer life begins."Evil Knight of the Old Castle","Devil of the Cavern"--the smile that naturally spilled out in front of the formidable enemies that appeared one after another was the proof of battle junkies!!
An exhilarating battle story where a severe battle junkie wearing a black robe rises to become a"hero"with his friends.
