Black Summoner

Kelvin begins his new life in another world after trading away parts of his past memories for exceptional power, extra skill points, and the rare rank of S-class summoner. The goddess overseeing his reincarnation, Melfina, even grants him a special advantage: the right to choose a companion before he sets out. Captivated by her from the moment they meet, Kelvin selects Melfina herself, trusting that his feelings will return even if his recollections do not.

With Melfina guiding him, Kelvin sets off to grow into his role—but bringing the goddess into a physical form requires a vast supply of mana. To gather it, he throws himself into battle, leveling up by taking on formidable foes and forging contracts with companions even more powerful than the last.
