Raphael Oriana

Raphael Oriana (ラファエロ・オリアナ) was the king of the Oriana Kingdom. He was brainwashed by Cult of Diablos until his daughter, Rose, euthanized him. After his death, however, it is revealed that he left behind vital information that ultimately exposed the cult's conspiracy within his country.

Personality
"I forgive you for your sins."

- Raphael's last word to Rose

Raphael had shown to be a wise and righteous king who would do what was right and stand up against evil, as he refused to give up his own daughter, Rose to the Cult of Diablos and even chooses to stand up against them by doing everything he could to ensure the protection of his daughter.

After he ended up being a Cult's puppet, Raphael hoped deep inside him that everything he had planned to save his daughter and expose the Cult and their collaborator plans would not be in vain, even if it cost him his life.

Even after his death, Raphael got what he wished for when he still has one trump card left as a final trick to the cult which finally happens when Rose put on the "Ring of Succession" and activates the recording inside the ring which exposes the Cult crimes and their collaborator Perv Asshat, the man that brainwashed him into becoming the cult's puppet.

Background
King Raphael belonged to a long line of monarchs who was aware of the deal made between the Oriana Royal Family and the Cult of Diablos. Raphael married Reina and the two sired their first child, Rose. Having discovered high levels of magic within the baby, the cult demanded that Raphael gave up Rose to them as per the conditions of their deal. However, Raphael refused to give up his child to the cult like his predecessors had done and chose to break the cycle. He forged an alliance with the Midgar Kingdom to build a force to rebel against the cult. When his daughter wanted to study at the Midgar Academy, Raphael approved it and sent Rose there to protect her from harm.

Raphael then discovered that Duke Asshat's adopted son, Perv was in league with the cult and began gathering evidence of the man's crimes. However, Raphael would noticed that he was being drugged which he correctly deduced that his food might be laced with the mind-controlling drug and realized this was a scheme plotted by the cult. Raphael tried to ask his wife to change his meal, but unfortunately his wife which he trusted to switch out his meals is a Perv collaborator and she make sure that he ate the laced meal without his knowledge.

Knowing he will lose sanity and become a mindless puppet, Raphael did one final act; he altered the "Ring of Succession" which was actually the key to the "Black Rose" so that the gateway could only be activated by Rose. Not only that, he recorded his last will and testament inside the Ring along with all evidence of Perv and cult's crimes. After finishing the task, Raphael hid the Ring from the cult on the ruins site, close to the Saisho Fortress.

When Raphael already become Perv's puppet, he is forced by Perv to do his order by going the Midgar royal capital to seize his daughter, Rose Oriana on the pretext of their engagement.

The Academy Disappearances
Unfortunately, despite Raphael's final message exposing the cult's faction within his country, the larger organization managed to use its influence to suppress the truth.

Abilities
While seemingly having no combat ability, being the ruler of the Oriana Kingdom, Raphael had great political power over the nation's internal affairs. Even the Cult of Diablos, who controlled the nation from the shadows, acknowledged the king's influence and brainwashed him before he could become a threat to them.

Magic
Raphael was able to engrave a message onto the "Ring of Succession", presumably through some kind of magic.

Rose Oriana
Raphael's love for his daughter, Rose was immeasurable. It was because of her that Raphael chose to turn against the cult and he did everything in his power to ensure her protection from the cult even if it results in his own death. Even allowing her to study abroad in the hopes Rose would be safe from the cult's clutches. After being turned to a mindless puppet of the cult, part of the real Raphael emerged to have a last conversation with his daughter, as he begs Rose to kill him to which she tearfully complies and entrusting the future of the Oriana Kingdom to her before Rose put him out of his misery.

Reina Oriana
Raphael loved his wife and trusted her to switch his meals in case they might be laced with the mind-altering drug. Tragically, Raphael didn't know that that Reina is Perv's lover and was complicit in turning him into a mindless puppet.

Perv Asshat
Raphael knew that Perv was affiliated with the Cult of Diablos and had gathered all evidence of Perv's crimes and stored them in the "Ring of Succession". Before Raphael could take action, Perv had drugged him, reducing the king to a mindless puppet who was only put out of his misery when Rose killed him. In the end, Raphael ended up getting the last laugh when Rose activated the "Ring" and exposing Perv's crimes during the man's wedding ceremony that would have given him the right to be king.

Cult of Diablos
Raphael aware about the Cult of Diablos and understands the organization's strength, because from the deal that have been made between the Oriana Royal Family and the Cult long ago. But, Raphael wanted to end the Cult's tradition on his kingdom and chooses to stand up to the Cult of Diablos in order to protect his daughter by plotting to gain independence form the Cult and build a force to stand up against them by forge an alliance with the Midgar Kingdom, even secretly sending his daughter to Midgar Academy to protect her from cult's clutches despite knowing that the Cult will make Raphael and his kingdom will suffer because of his treachery and will try to seize control of his kingdom.

After Raphael becoming their puppet, he hoped that all of his plans in order to save his daughter and expose the Cult and their collaborator crimes would not be in vain, even if it cost him his life. In the end, Raphael got what he wished for when Rose put on the "Ring of Succession" and activates the recording inside the ring which exposes the Cult crimes and their collaborator Perv Asshat, the man that brainwashed him into becoming the cult's puppet in public, although he can't divulge the organization's name to the Oriana's people.
