Fantastic Beasts and the Night Keeper

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.
