Students are trapped inside a school with no way of getting out except to "graduate."
>In both of these cases, "graduating" is not how graduating is usually done and the students are all pitted against each other with doubt.
>Semi-Spoiler: It's not really a spoiler, since it's hinted early on in both mangas that these students are all being watched on surveillance tapes/cameras
>It has the whole mystery& puzzles kind of feel that keeps you reading on and on until you have to stop and wait for the next chapter.
