In the contest, the high school kids had to draw their own original manga with a given theme. Using existing popular characters from manga, anime and game was not allowed at all. On the other hand, they were allowed and encouraged to draw "graffiti" on the walls of their booth in their spare time. Graffiti is just graffiti, so they were able to draw anything they wanted, including anime and manga characters. That is one of the Manga Koshien's tradition. Please check the graffiti, you may find out what type of characters are popular among Japanese high school manga fans today. Please don't forget, they are all teens and amateurs!
