Denki-Gai no Honya-san

The "youthful bookstore comedy" revolves around the folks who work in a manga shop deep in a certain "Electric Town" neighborhood. ("Denki-Gai" or "Electric Town" is a popular name for shopping areas that specialize or used to specialize in electric and electronic items, like Tokyo's Akihabara.) The protagonist Umio works part-time at "BOOKS Umanohone" along with his senior at work (but not in age) Hiotan. As many dedicated manga fans visit the store, there is always something going on.
