Description
Graf Louis Yu Almeida is the primary antagonist of the series. He is the wealthy and powerful head of Glaucos Pharmaceuticals, a vast corporation with enough influence to own a theme park named Glaucos Park, a castle, and an entire village. His obsession with owls, a symbol of wisdom and the goddess Minerva, is a defining aesthetic; he is frequently seen wearing an owl mask and adorning his surroundings with owl imagery. He runs a massive pharmaceutical company.

Almeida’s driving motivation is the creation of a "sacred girl" or "perfect maiden" through horrific human experimentation. To this end, he developed a powerful psychosomatic hallucinogen called Fräulein Eule, a German name meaning "Owl Girl". He used this drug in a secret research center located in the town of Euren Spiegel to systematically experiment on young girls. The process involved extreme torture, including using the children of his own researchers as subjects, kidnapping others, and subjecting them to electroshock, rape, and other brutal procedures. One of his primary subjects was a girl named Aisha, the daughter of one of his doctors. A catastrophic accident at the Euren Spiegel facility resulted in the death of all its inhabitants, turning it into a dead city.

In the story, Almeida is the shadowy figure responsible for much of Fujiko Mine’s trauma and the manipulator pulling the strings behind the series' events. He hired the master thief Arsène Lupin III with the unusual request to "steal Fujiko Mine" for him. It is later revealed that he had been manipulating Fujiko’s actions and even her encounters with Lupin and his associates, Daisuke Jigen and Goemon Ishikawa XIII, all to draw her back to him. His obsession with Fujiko is immense; he built an entire theme park attraction called the "House of Fujiko".

A significant revelation is that Almeida dies before the events of the series begin. His death, which occurs quietly sometime prior to the first episode, is confirmed by his butler. The figure in the owl mask who appears throughout the story is actually a disguise maintained by his last and most important victim, Aisha. Paralyzed and reduced to a near-corpse that can only communicate with eye movements, Aisha took over Almeida's identity with the help of his servants to continue his experiments in her own desperate quest to vicariously experience life. Through her manipulations, she implanted her own memories into other girls, including Fujiko, causing them to believe they were the ones who suffered at Almeida’s hands. His notable abilities were not physical but stemmed from his immense financial resources, his control over a massive pharmaceutical empire, and his development of the powerful mind-controlling drug Fräulein Eule, which could be administered or even spread through the air.
