Assassinationclassroom gravity falls crossover
Shiota nagisa. A short boy with long blue hair held up in two ponytails, soft blue eyes and a sweet smile.
Akabane karma. A tall redheaded boy, chaotic in the soul and eyes like burning mercury, with a honeyed smile.
Both of these quiet yet bold and adventurous boys are sent away from their home, to a place known as gravity falls. A small little town with a weird name and weirder people. The first two weeks were incredibly odd, always some mystery story or rumor going around the little town. Until Shiota Nagisa stumbled across a journal in the woods. Could this be the answer to all those unsolved mysteries? Who can he truly trust ? Why is the red haired boy acting so suspicious?..... and .. when he flips to the back of the book .. why isn't there a signature?? Who . Is . The author??
