I Sold The Traitor For 20 Million… And Raised An SSS-Rank Angel!

Ethan Hayes summoned a rare epic succubus, but right during the ceremony, she betrayed him and began to fawn over a rich heir. Everyone considered the guy a fool when he unhesitatingly demanded twenty million for the traitor and severed the connection. But none of them suspected that Ethan had awakened a unique familiar evolution system.

Taking the arrogant major's money, he finds a crippled angel, Chloe, with damaged wings, whom everyone had rejected as a failure. Investing resources in her healing, Ethan unlocks the path to her hidden evolution and awakens a legendary seraphim. Now the former pet and her new master will have to face the true power that terrified the entire academy.
