SSS-Rank Bone Dragon: Rise of the Forsaken

Common-born Leo awakens the ridiculed F-rank talent Bottom-Feeder, prompting his S-rank Frost Phoenix fiancée Luna to publicly annul their engagement. Noble Charles Watson then brutally assaults him and abandons his body in a sewer. At death's door, the Omni-Evolution System activates, transmuting Leo's ability into the S-rank Abyssal Black Drake. He survives, escapes, and later cripples Charles in an academy arena duel before rejecting a military commission, igniting a blood feud with the powerful Watson Clan.

During a wilderness trial, Instructor Robert, bribed by nobles, attempts to assassinate Leo. Leo kills him and delivers his head to the Watsons as a war declaration. Operating as Nightfall, he claims the Frost Lotus at a black-market auction and cripples heir Victor Watson in a death duel. Desperate, Lord Arthur Watson conspires with the Shadow Guild to poison dignitaries and launch a coup. Leo storms the banquet, executing Arthur and Guild Vice-Leader Malachi. A dying Malachi detonates beast-luring incense, summoning a horde led by Beast King Cerberus as General Hayes betrays the city.
