Hideyo Masuda

Mephistopheles is the child of Aya and Hitoro Takuza, and was originally named Hisao Takuza. He was born a healthy child and no abnormalities were observed, except by himself. From a very young age Hisao observed his ability to shapeshift, often playing tricks on his parents by shapeshifting into another child on a trip to the park and even changing into his father a few times, although such a huge change caused excruciating pain for the child, and he did not do it often. The tricks were never discovered by his parents, although they certainly stressed them out to extreme levels. His parents were often confused by his apparent lack of hunger or thirst, but the Hisao would eat and drink when prompted.

Once Hisao matured into a child rather than a toddler, it was noted that he was incredibly intelligent and mature. He learnt basic manners very quickly, showed extreme aptitude in the sciences and maths and won a lot of scholarly prizes at his school. The shapeshifting tricks continued into this period of his life, but they were never malicious. Hisao only saw it as harmless fun and did them very sparingly, maybe once or twice a year. Eventually they drove his parents to breaking point. His mother had a panic attack when he disappeared in the middle of a city street and she hit her head on the pavement on her way to the floor. After months in hospital Aya was eventually released, albeit with severe brain damage and wheelchair-bound. His father was forced to quit work and claim carer's benefits while caring for her, and spiraled into a dark world of depression and alcohol. During this period Hisao was often left on his own, uncared for, and had time to contemplate on his mistakes. After a few months Hisao decided it would be best for him to leave home and hit the open road.
His father didn't notice his absence for two days, but by the time he alerted the police Hisao had already shapeshifted and headed south. Officially, Hisao has been declared dead by the police and his father committed suicide, leaving his wife to starve to death a year after Hisao's exodus.

After leaving his hometown, Hisao headed towards the south of Japan. On his way he spent nearly five years in Tokyo posing as a college student (this was also the time that he discovered that he could shapeshift into forms of his own design) studying Medicine. After completing his degree and specialising in gynecology Hisao left Tokyo and headed South, picking up jobs as an unskilled laborer posing as some John Doe or another. The jobs usually lasted a week or two and he made a enough money to pay for hotel rooms and travel. He was happy during this period, easily making friends in each town and eventually realised he was gay at the age of 15 after a confusing night with a co-worker. Coming to terms with his sexuality was easy for Hisao, he was thankfully spared the judgement of society as he never spent too long in one place. One evening after a day spent working on a leaky roof on a house, Hisao got lost on the way to his hotel.

While picking his way through a valley in the south of Japan, completely lost and alone, Hisao came across a strange building, huge and surrounded by walls, with spotlights and guards. Obviously, his first reaction was to investigate. He reverted back to his natural form for the first time in years, and was pleasantly surprised to find that his body aged in its absence. Hisao managed to sneak in through [DETAILS CLASSIFIED]. Once inside the facility he took on the guise of a researcher and headed deeper into the facility, discovering vast amounts of weird and wonderful objects and beings. He was eventually discovered when he ran straight into the body he had stolen, the alarm was raised and he was immediately secured, contained and protected inside a cell. He was given the name "SCP-2030" for the time being.

In the following months Hisao was interviewed, tested and interviewed again by the researchers at the SCP facility. Many of the tests were inconclusive, and to date the researchers do not know exactly how SCP-2030 shapeshifts, but they worked out that it was done at an atomic level and that his atoms are physically destroyed and remade - hence the extreme pain. He made friends with many of the researchers during his incarceration, and they eventually stopped referring to him as "2030" and dubbed him "Mephistopheles", based on the character in the play "Doctor Faustus". The months turned to years, and Mephistopheles led a fairly happy life. He was given a pretty long leash when it came to roaming the Facility, although this was never mentioned in the official documents as the higher-ups would definitely not approve. He spent a lot of his time in the facility brushing up on his medical science, and learned a lot from the personnel at the facility. He was given access to all the latest medical journals and dissertations, and delved deeper into his ironic fascination in Gynecology.

By the time Mephistopheles was 22, he had caught the attention of the O5 team, who were putting together a group of agents to round up three Keter class subjects that had infiltrated the Japanese government and were planning on launching Nuclear Warheads at every major power on Earth. They desperately needed somebody on the inside, and they found their salvation in Mephistopheles. He disguised himself as a Japanese official and fed the SCP Foundation vital information in the downfall of the three subjects. The subjects are now contained.

After his successful operation as a field agent of the SCP, Mephistopheles stayed at the facility another six months until he was offered another taste of the outside world - he was to be stationed as a guard for a local school - one in which young subjects were sent to live life normally. He was to be stationed under the name "Hideyo Masuda" after two famous Japanese doctors, and given a job as a gynecologist and GP in the local hospital in a nearby city. He lives with another agent, [DATA EXPUNGED].
