Currently the most popular manga on Urasunday Magazine, Sekai Oni follows the story of a little girl called Shinonome Azma. Azma is abused by her family and this has made her quite unstable, to the point where she has been driven to the limit. She now has the rare sickness of Alice in Wonderland, that makes her see things that shouldn't be there reflected on mirrors, water, glass, etc. Everything starts when the things she sees start affecting directly the world everyone else sees, and the barrier between reality and illusion breaks apart, like a mirror falling to the ground.
