In the beginning we would think that this manga is just like any other manga, full of fan service and a rather pathetic guy. The synopsis is misleading your preconception of what this manga really is. The mystery genre is the real gem of this manga. It keeps teasing you and makes you yearn for more. As we read more we start to think about the mysteries in this manga such as how they got to this island. Don't let ecchi genre throw you off, there is very little of those scenes.
In terms of character development, as we learn more about our main character, we soon start to see him being put in situations where he begins to mature and become more reliable. There isn't exactly situations where they battle for survival but they need to adapt to the situation they are in.
If you are looking for a relatively short but interesting read that will keep you engaged and wanting more, feel free to give this manga a go.
