Profile of Ryunosuke Ameo
Source: Fate Zero ©Nitroplus TYPE-MOON・ufotable・FSNPC
A young man who became a serial killer after repeatedly killing people in order to understand the meaning of "death". When he was troubled by his "loss of motivation" to kill, he discovered an old book about the Holy Grail War at his parents' house, and as a result of performing a "ritual murder" based on it in Fuyuki City, he accidentally summoned a Caster Servant. Without knowing anything about the Holy Grail or magic, he is drawn into the Fourth Holy Grail War without even realizing that he is participating.
Madness Mode

Cheerful and cheerful. While he is good at reading the subtleties of other people's feelings, he is always positive and constructive without getting hung up on small details. He is a good young man who does not get discouraged by failure and enjoys life to the fullest with his natural inquisitiveness and strong curiosity. He's usually such a listless guy that even talking feels like a chore, but when he's committing murders, he becomes humorous and talkative. He was popular with girls on the town at night, but the women who were attracted to him are turned into bloody lumps of flesh.
COOL

He was born with a lack of morality and ethics, and is puzzled by the fact that the artistic and philosophical nature of his deeds is not recognized by the world. He describes things that suit his sensibility as "COOL". Since murder is an art form to him, he shows no interest in the victim's money or valuables. This is also one of the reasons he is able to evade police investigation.
The worst combo with Caster
Source: Fate Zero ©Nitroplus TYPE-MOON・ufotable・FSNPC
He respects Caster as his master in artistic murder, and calls him "Bluebeard's husband". After being summoned, they went around kidnapping children around Fuyuki City together, resulting in many casualties. And, agreeing with the idea he unintentionally presented, he watched Caster rampage in the Mio River while blending in with the general public.
Ameo Ryunosuke's Abilities
As mentioned above, he is not a regular magician, so he does not have magical abilities, but the magic circuits flowing in his blood are still alive, and since his ancestors imitated onmyoji, documents related to magic were left in his parents' storehouse. As for maintaining her husband's existence in the world, he was able to avoid any problems thanks to the soul-eating he did while committing crimes and the ``Rakunaga Castle Textbook.''
A bundle of talent?
He has a genius technique for destroying evidence and disrupting investigations, and despite having killed more than 30 people in the past in a haphazard manner, this special skill has never allowed the investigation to reach him. This time too, he made full use of his concealment techniques, and the only ones who were able to find him were Waver, who traced him through a magical aspect that he hadn't considered, and Assassin, who followed them using his Concealment skill. Even though he was limited to ordinary humans, his skills and talent as a killer can be seen from the fact that even Urobuchi praised him for his surprise attacks, assassinations, and schemes.
What is the true identity of the Heroic Spirit Caster?
Source: Fate Zero ©Nitroplus TYPE-MOON・ufotable・FSNPC
A heroic spirit that was summoned by Ryunosuke Ameo inadvertently during a ritual he performed for fun. Since there was no catalyst, a pleasure killer with a similar personality to the summoner was summoned. Like Ryunosuke, he is not an official magician, and the ritual was also haphazard, but he appeared simply because there was no magician to summon the seventh person (Caster).
Summoned as an evil spirit

Since it was a summoning without a catalyst, he was attracted to Ryunosuke as an evil spirit with similar nature and tastes. Gilles de Rais himself was a knight who was worthy of being called a hero in life, but this time he was called upon in his later years, when he went mad after Joan of Arc was executed, fell into black magic, and killed many children.
The Aesthetics He Desires
Source: Fate Zero ©Nitroplus TYPE-MOON・ufotable・FSNPC
He has an abnormal aesthetic and behavioral pattern when it comes to murder, and he massacred many children together with his friend. They use the sacrifices as materials to create nauseating crafts. Like their master Ryunosuke, they are not formal magicians, and so are extremely ignorant of the golden rule of magicians, "secrecy of magic" (the obligation to hide the existence of magic from the general public), and use magic without even trying to hide their existence from the general public. After believing Saber to be Joan of Arc, they pay no attention to the Holy Grail War, insisting that "my wish has already been fulfilled," and indiscriminately committing heinous acts such as kidnapping and murdering children.
A strange obsession with Saber

He believes Saber to be Joan of Arc, who fought alongside him and worshipped her in life, and is trying to free her from God. When Saber is involved, he tends to lose all sense of reason, and when he carelessly tried to contact her, he was captured and followed by Kotomine Kirei's servant Assassin, and his base was exposed. As a result, Tohsaka Tokiomi, the second owner of Fuyuki City, and Kotomine Risei, the supervisor of the Holy Grail War, learned of their true identities and considered them dangerous, and each master targeted them along with Ryunosuke for extermination.
The name Bluebeard

Also, their nickname "Bluebeard" and even their real name were discovered. Furthermore, the fact that he left traces of magic in the drainage water backfired, and his workshop, which he used as his base, was discovered by Waver, and was destroyed by his servant Rider along with the "art" he created with Ryunosuke.
Caster's explanation by Nasu Kinoko
In the story, Caster is depicted as a murderer controlled by insanity, but Nasu Kinoko has stated his personal opinion that "while his actions are the very act of stalking Saber, if anyone imagines the indescribable end of Joan of Arc in historical fact as someone like his ex-boyfriend, Caster's words and actions may seem heartbreaking."
Faith
As a result, he had a stronger faith than anyone else. For him, it was unthinkable to execute a girl who was supposed to have heard the voice of God as a witch. And he committed a heinous act to show the absence of God. The disappointment he felt when he was betrayed because he believed in God more than anyone else made him a monster.
Abilities of Caster
Source: Fate Zero ©Nitroplus TYPE-MOON・ufotable・FSNPC
His abilities as a knight and magician are below par for a Servant, but he uses summoning magic with the assistance of his powerful magical book, the Noble Phantasm "Prelatis Spellbook." As per the character profile, he is not familiar with common knowledge of magic, but as a former marshal, he is impressive when it comes to judging the situation on the battlefield and choosing the location of his workshop.
Battle Style

His battle style is a strategy of quantity using sea demons that resemble starfish and can be summoned almost infinitely. Though it was a simple tactic, its effect on opponents who only had anti-personnel Noble Phantasms was immense, and Saber, whose anti-fortress Noble Phantasm was sealed away, was at a disadvantage. Even after Lancer came to her aid, she continued to hold the advantage until halfway through the battle.
A giant monster modeled after the god Cthulhu

On the other hand, normal-sized sea monsters are no match for the anti-military Noble Phantasm, and Rider is unilaterally crushing the sea monsters he summoned in large numbers to protect his workshop. Towards the end of the game, he summoned the Great Sea Demon, ignoring all control, and it is a gigantic monster over 100 meters tall, modelled on the god Cthulhu, which he fused with himself. In addition to its gigantic size, it boasts agile tentacles capable of capturing a fighter plane, and a regenerative ability that allows it to instantly recover even if half of its body is blown off, overpowering even Rider's "Royal Army". In addition, although it is low-ranked, it has the skill "Artistic Appreciation", and if he sees a Noble Phantasm with an anecdote in the performing arts, there is a low chance that he can discern its true name.
The tragic end of Ryunosuke Ameo and Caster
Source: Fate Zero ©Nitroplus TYPE-MOON・ufotable・FSNPC
When Ryunosuke went to see Caster summoning a sea demon, he was shot in the stomach and head by Kiritsugu, who concluded that Ryunosuke was "Caster's Master" based on his behavior, and died. But even at the moment of his death, he felt the reality of death he had been looking for...he was overwhelmed by the fact that he had been able to see the color of his own blood and organs, and he died with a smile on his face.
The last scene I saw
Source: Fate Zero ©Nitroplus TYPE-MOON・ufotable・FSNPC
Lancer discarded the Yellow Rose of Certain Death to defeat the Great Sea Demon, and thanks to this, Saber was able to use her sword of guaranteed victory, destroying the Great Sea Demon with a single blow. However, in his final moments, he remembered that his own honor was something that shone as brightly as this light, and was able to regain his sense of self. In the anime, a scene was inserted in which Jeanne smiles and reaches out her hand to Jill in the final moments, with a dazzling light behind her. This is probably a scene in which Jill, who had not yet gone insane, "gave a joyful blessing together with Jeanne."
Summary

The two committed such a crime that the Holy Grail War was temporarily suspended. I think it was karma that they ended up with such a sad end after causing so much chaos in the Holy Grail War. If you want to see the two of them go crazy, be sure to watch the anime!
