Disney Twisted-Wonderland: The Manga - Book of Octavinelle

Three months ago, Yuuta "Yuu" Mito was a part-time worker at a Chinese restaurant in Wakayama, Japan. Now, the teenager has been stranded in the magical realm of Twisted Wonderland after a black horse-drawn carriage ran into him while he was delivering a customer's order. Unable to return to his original world, the magicless Yuu found himself enrolled at the prestigious Night Raven College in the meantime.

A strange happening around the campus emerges following the exam season, with several students sprouting sea anemones from the top of their heads—including Yuu's friends Grim, Ace Trappola, and Deuce Spade. Matters only worsen when those affected are told that they have become indentured servants to Octavinelle's housewarden, Azul Ashengrotto, as a result of magical contracts they had previously signed with him.

Unaffected since he never entered a deal with Azul, Yuu must find a way to break the contracts and save his friends. But completing this task without any magic of his own may prove more daunting than he realizes, as the odds begin to stack against him.
