Richard, a broke, sharp-tongued black-market vet, gets evicted from his rundown flat and is hired at an astronomical rate by the mysterious noblewoman Catherine to be the night keeper of Ashford Manor. His plan is simple: coast through the shift, collect his paycheck, and get out. But when he stumbles into a forbidden zone to save a mortally wounded Abyssal Royal Squid, he inadvertently completes the seal on an S-class calamity—and the overflow magic floods straight into him. Suddenly, the entire world thinks some legendary hidden powerhouse just obliterated the disaster. He keeps healing beasts for the money, but the more he heals, the stronger he becomes, earning him an A-rank agent badge from the DMTC. As he digs deeper into the manor's secrets, he uncovers the horrifying truth—this is no mansion, but a crumbling prison built on the souls of fourteen ancestral guardians, barely containing thousands of calamities. And he has been chosen as the sole heir to inherit their power and end a century-long nightmare.

It is said that Marco Colombo, the heir of the Colombo family of Chiron, is holding a wedding for his mistress, Gina Bilotti, today. The scale is ten times grander than when he marries Isabella Pratico in a political union. I lean against the ebony railing on the second floor. Sipping my red wine, I watch the lively scene of clinking glasses and mingling guests below with quiet amusement. Gina is definitely favored—she is even wearing a ruby necklace. One should know that set of ruby jewelry is an heirloom of the Colombo family. It is something only the Donna and the wife of the heir are allowed to wear. "You must be Isabella, the one Marco who does not love." A voice suddenly comes from beside me. I turn my head and see the woman wearing the ruby necklace before me. Gina has come up to the second floor at some point and is now looking at me with a cunning smile on her face. I freeze for a moment, not yet able to respond. She suddenly grabs my hand and yanks it hard toward herself. There is a sharp tearing sound, and the hem of her wedding dress rips open with a long tear. Gina lets out a cry, and tears immediately stream down her face. "Mrs. Colombo, why did you tear my wedding dress? Marco specially commissioned this from an independent designer just for our wedding! "If you really cannot tolerate my presence, then I will break up with Marco today and leave Chiron…" The surrounding guests all lift their heads and glare at me angrily. I am stunned because I am not Isabella. I am the new wife of Marco's father, the woman of the current Don, and the Donna of the Colombo family.
