The Grey Wolf - Gosick x Assassin Male Reader

(Y/N) Frye, brother of the Assassin Lydia Frye, has been sent overseas in order to infiltrate the Kingdom of Sauville, a small European country bordered by Switzerland to the north, France to the west and Italy to the east that reportedly holds a Piece of Eden. Undercover as a British student at the St. Marguerite Academy, he encounters Victorique de Blois, a mysterious girl who is also a genius. Together, the two of them solve various mysteries all across Sauville; mysteries that help lead the young Assassin closer to the Piece of Eden, as well as the mysterious Grand Master of the Sauville Rite.

Just finished watching Gosick yesterday. This is definitely one of my favorite anime of all time. Goddamn, how did I only find out about this anime 11 years after its release? No matter, now it's time to try (and fail) to add an Assassin's Creed feel to it.
