GTO (GREAT TEACHER ONIZUKA) is an amusing if curious story to read. In many ways GTO is probably rather indicative of many manga currently being written. It deals with a male protagonist who leads a rather blessed life in his pursuit of happiness. Along the way he helps many people around him and makes the world generally a better place. This is despite appearing to be quite the irreverent punk that his character is based on.
