The Betrayed Summoner's Revenge

The protagonist lives in a world overrun by Aberrant Beasts. He originally awakened an S-Class Ability, but it was stolen by the family he trusted most, and he nearly died at the hands of an Aberrant Beast. Fortunately, on the brink of death, he awakened the 'Strongest Divine General System.' This began his path of revenge, slaying Aberrant Beasts, summoning Divine Generals, and avenging himself, walking further and further down the path of the strong.
