[FGO + Detective Conan] The Magician's Melancholy

We will meet beyond the bounds of fate someday. Furuya Hajime used to be a shut-in. Though he was a strange nonhuman being, he insisted on staying at home. Then, by a twist of fate, he became a Master at Chaldea. He could tear down city walls with his bare hands and rip Demon God Pillars apart, and in the end, he nearly brought the world to ruin in pursuit of his wish, yet he insisted he was a good person. Furuya Hajime: Honestly, I really am on the good side, you know? Even if I often want to destroy the world after saving humanity. His thinking is pretty dangerous, but he's actually a fairly gentle person (Oh my gosh, another "yasashii" type, how cliche). The protagonist's daily life: The doctor is right, Karna is right... No, little sun, don't say anything yet. You old scoundrel Merlin, let go of the doctor! Fou, kick that Merlin! The doctor is pampered from beginning to end. The doctor is the world's greatest treasure! The protagonist's pairing is Karna. Side pairings: Akaai, Merlin x Romani.
