Story 3 Concept #1
Ao no Exorcist xover HP
It was two weeks before his birthday when the first odd looking letter arrived. Everyone said it was a prank, and burned it away. At the strike of midnight on December 27 Rin Okumura gave in and replied back. Thus his journey began.
Rin is in the same year level as the Weasley twins, so two years ahead than Harry.
Rin was upset with himself for always getting into trouble, for breaking his word and for the envy he felt at the close relationship his younger twin had with their dad. Rin knew they were keeping a secret, but he pushed it down.
He didn't want to be a burden, or a disappointment to his family again and decided to attend secretly by requesting to transfer to a night school and telling a half truth fib. He was accepted at Hogwarts, given a portkey to travel back and forth from the school. He goes to Hogwarts from Japan, and arrives back home the next day. Prepares for muggle school in the morning and goes to sleep. The schedule was eating him up by the time he reached fifteen and dropped out of muggle education, fully intending to get part time work and attend Hogwarts, or pretend to get work just so he could stay at his school. No one knows of his situation and Rin intends to keep it that way.
The events leading to his reveal was caused by stress from the end of year exam, his lack of sleep and the events of the school year. When he was persuaded to attend True Cross Academy and go to cram school, Rin was only grateful that he was on Hogwarts school holidays, despaired at his assignments and dreaded when the new school year starts. When he goes back to Hogwarts everyone assumes he had gotten into his inheritance as some fire cat, so he was able to be free in his school and no one had a problem unless he accidentally destroyed things.
He's on a scholarship at Hogwarts, and so as to remain, Rin actually has to study very hard or disappoint himself and his family who do not know. His doodles in muggle edu are actually magical study, a few of his manga's are just his school books under a concealment charm he learnt in first year. His determination in keeping his secret and protecting his family had made him a prodigy in charms, DADA, and ancient runes.
When his cram school friends turned their backs to him, Rin, already stressed for OWLs, broke down and retreated to the monastery with all his belongings. Writing a letter to Mephisto the muggle way, Rin decided to transfer his Exorcist training to France and lived there for three months, taking the Exorcist exam before his school started. He managed to pass as a Middle-Second-Class knight and tamer. He told the French Exorcist branch that he was intending to study in a University soon as an excuse to stay in Hogwarts, and they agreed to call him if they were short on number or an emergency if he takes on the name Agent Gabrielle. He agrees.
Rin decided to make truth in his lie and applied for a part-time study online in a university. He takes on more missions at the end of year holidays and lives in France during that time.
Since his acceptance to Hogwarts, Rin had to learn English efficiently before school started, and translated his muggle edu materials to English as often as possible. He was able to read, listen and write efficiently and is too embarrassed with his strong accent to talk. Eventually, throughout the year he was comfortable to talk, and by the end of the year was able to converse fluently. Because of his constant interactions in a native English country, Rin unintentionally developed a posh English accent whenever he spoke English. He was forced to learn Latin and ancient writings during his school and acquired the ability to learn any language easily. At thirteen he was learning French as some texts was written in that language. When the tri wizard tournament came, he interacted with the foreign students, gained a French accent and unknowingly began learning Bulgarian by accident. By the end of that year he was pressured to keep in contact with his foreign friends and was able to retain the languages. Around his fourth year he had encouraged Harry to teach him parstletongue as a form of distraction and it worked, with the Weasley twins, Ron and Hermione joining in later. At fifteen he began learning Russian and German, nearing his sixteenth birthday he started Chinese, determined to learn as many of its dialect as he can. Despite Japanese being his mother tongue, Rin rarely interacted with it, the only thing keeping up his skill was manga and anime.
As an Exorcist, he was mainly summoned during the height of an emergency, usually in Japan, under his alias as Agent Gabrielle, and only the French branch knows of his true identity. Rin confuses most Order branches with his heritage as he spoke many languages fluently, though usually assuming that he was French. During the periods he does missions, he quickly gains a name for himself as the fastest promoted Exorcist and receives multiple field promotions, though Rin doesn't care and would usually forget his position as an Upper-First-Class Exorcist until other starry-eyed Exorcists gossip his name.
When Rin is out on missions, the French branch provided his standard uniform: a white and blue accented Volto Larva mask or a Moretta mask; a full length white overcoat streaked in blue with a deep hood; white tuxedo suit with blue accents or a black leather pants and a white long-sleeved tunic with black lining, the length reaching mid-thigh, a blue string tied in a bow at the neck; a long navy scarf, winter or summer texture; white or dark blue gloves in black lining; a black fedora with a blue streak and black, leather, combat boots mid -shin height.
Rin has an interesting relationship with the Japanese Paladin, Arthur Auguste Angel and his chosen elite, often requested to join in their missions. Rin is not forced because he is not under the Japanese Order Jurdistriction.
In Hogwarts, Rin discovers he is scarily adept in mind magic, unintentionally going into other people's minds and driving Snape irritated. He was then confronted in Care for Magical Creatures with the revelation of a weak empathy ability, unless he focuses on his target. Throughout his double life, Rin usually faints once a year due to the pressure and is forced for at least a week of rest in the hospital wing. At thirteen, he was given a time turner with a warning to sparsely use it, he becomes even more cautious once Rin realised that Mephisto was the Demon King of Time and Space not using it when he was in close proximity of the academy or in Japan. At seventeen Rin is pulled in the final battle against Satan and his identity is revealed. Soon after the battle he receives a message of the events transpired in Hogwarts and leaves immediately. Graduated as one of the top students, Rin is left adrift, not knowing what to do but leaves eventually to focus on his uni studies full time in an accelerated program. He graduates with an honour in psychology, a degree in criminology, and a diploma in medicine nearing his nineteenth birthday. He joins the war after his university graduation, academically exhausted, not noticing his brother and past friends watching his graduation in disbelieving shock. They do not see him leave.
During the battle, Rin jumps in front of Fred and is hit with the curse and fell. In shock and anger, Fred instantly retaliates, the death eater dead before he hits the ground. The red-head rushes to Rin only to freeze at the sight of something glowing at his chest, the light growing bigger and bigger, pulsating until it explodes into tiny golden particles. When the light dims, Rin was not there and thus, the Battle of Hogwarts ended.
Meanwhile, Rin's disappearance did not go amiss in the demon world, the news devasting his family and friends, only Mephisto remains confused at the weak, faint presence of something in his domain.
