The story happened on the day he was 11 years old. Harry received a letter from Swartz, became a student at the School of Magic.He met good friends Ron and Hermione at the school, Malfoy, who was always against them, and Snape, who hated the magic medicine. As a result of the accident, they found a big three-headed dog in the school restricted area. They thought the dog was guarding something, and Snape tried to steal it. At the same time, the unicorn in the forest was killed, Harry who was punished for working in the forest seemed to see Voldemort, and the horses in the forest warned Harry. After a research by the three, they finally knew that what the dog was guarding —— a magic stone that could make elixir. So they tried to attach Snape, and finally, when Harry reached the hidden place of the magic stone, the people there were not Snape, nor Voldemort, but their professor of black magic defense, Chilo. Through the Eris Mirror, Harry got the magic stone, and Chilo tried to catch him at Voldemort's order, but Chilo's skin was burned when he touched Harry, and eventually, while Harry fainted, Principal Dumbledore came to save Harry and succeeded in getting the magic stone.
