Adventurer (Bell Cranel).
Gods who created the Universe descended from Heaven to live among humans on the condition they swore to never again use their godly powers. The Gods only remaining power is the Blessing, which they grant to humans to level up their powers (Similar to how characters level up in video games). These humans, known as Familia, become that God's family. Bell Cranel, the only member of the Goddess Hestia's Familia, is almost killed by a Minotaur. He is saved by Aiz Wallenstein, a high-level adventurer and member of the Familia of the Goddess Loki, and falls in love with her...
