Black Summoner - S01

To get ready for reincarnation in another world, Kelvin trades away some of his memories from his previous life for powerful abilities, extra skill points, and an S-class summoner title. As a bonus, the goddess handling his rebirth, Melfina, lets him pick any companion to give him a head start in his summoner role. Kelvin, who has fallen head over heels for Melfina at first sight, immediately chooses the deity, sure that his passionate feelings for her will come back even without all his memories. Kelvin sets off on his exciting new journey with Melfina as his guide. But to summon his beloved goddess' physical form, he needs to gather a lot of mana points, and the best way to do that is to level up by fighting strong enemies and making contracts with even stronger companions.
