Adored by the Four Great Elemental Kings

Ask, the second son of a prestigious noble family of mages, was born without emotions or magical power. Despised by his family since childhood for being defective, he was eventually driven out of the main residence. Soon, it’s revealed that his deficiency was actually a talent as a “vessel” necessary for contracting with the Four Great Elemental Kings. Chosen as the qualified candidate to host the elemental kings who govern the world’s fire, earth, water, and wind, Ask regains his emotions and obtains immense power. He decides to abandon his house and enjoy his second life! Source: MU
