Reborn Beastmaster: Only My Succubus Never Betrays

Xavier Woods died once and came back with a beast-taming system awake in him. In the life before, the S-rank six-winged angel he was bonded to betrayed him. This time, when the choice comes round again, he gives up the angel and takes Lilith instead, an F-rank succubus who is damaged and beneath everyone's notice. The room laughs at him for it. He triggers the light and dark twin bloodline sleeping in her, which reads SSS. Nobody in the room laughs after that. He takes the national entrance examination apart, climbs the ranking to the top, and with Sophia and Adrian goes into the Land the Gods Abandoned, pulling people out of trouble there. Lilith's origin comes out on that trip: her father is the Demon God. At an auction Xavier bids against Ethan for the Sword of Light. Then comes the Skyreach Sanctum entrance examination, and what Lilith evolves into there.
