Icon "Bento" appears to kind of appear like an outline of a handgun or a boomerang. Two vertical lines that appear to look like chopstick are touching the edge of the gun. The attention of the object is drawn towards the top left corner. The design is very simplistic, and is not a very pleasing aesthetic. It looks like a draft for a better, full, and more attention grabbing logo. It is impossible to say what organization/idea/letter/alphabet the icon represents.
