Croquis Pop, Vol. 3

There are dark forces at work that seek to manipulate the young croquer
Da-Il for their own ends. When he and his friends are held hostage on
the subway in the Dead Zone, Da-Il learns more about the fuel for his
croquis from a mysterious croquer with a camera. But not all teachers
have benevolent motives...and, as Da-Il discovers, some are downright
deadly.
