Making APTX4869 at Hogwarts

[Protagonist: Miyano Shiho/Haibara Ai + no romance + no System + based on the Harry Potter story and world] [Harry Potter fan fiction + Detective Conan fan fiction]

When eighteen-year-old Miyano Shiho comes to in the aftermath of an explosion, she finds herself in an eleven-year-old body at the Leaky Cauldron in 1991. Her scientific worldview is completely overturned. An experimental subject for APTX4869, she was thrown from the laboratory into this world of magic after a mysterious catalyst was added to the formula.

Beneath Hogwarts’ starry ceiling, she engages the secretive Snape in a silent battle over the boundary between potions and chemistry. In Devon’s world of alchemy, she discovers that the Philosopher’s Stone can do far more than grant immortality and turn lead into gold. And as she repairs the Time-Turner, she bridges past and present, making the future impossible to predict.

When the Chamber of Secrets opens once more, the basilisk’s golden eyes reflect two identical figures. The Goblet of Fire at the Triwizard Tournament spits out an enemy from the past. And in the Mirror of Erised, the smile of her sister, Miyano Akemi, is slowly becoming real…

The raven of time and space has arrived. She must use a scientist’s reason and a witch’s magic to find an answer between the lure of immortality and the collapse of time and space. Which path, in the end, will lead to the one and only truth?
