Instant Teen is definitely a strange manga. I'm not going to tell you the plot of the story since most of the other reviews have. Just my personal opinion of the series. I actually really enjoyed it. The first time I read it I was in fifth grade and picked up the first two volumes at a used book store. I really enjoyed it but I ended up selling them as I couldn't find the last two volumes and I was getting rid of a bunch of mangas I didn't read anymore. A few years later I decided to get all four volumes so I couldfinally read the story start to finish. The story is kinda all over the place so its definitely not the best manga out there but it's good. It has an enjoyable plot and lovable characters. Overall if your'e looking for a quick read then I would definitely suggest picking up Instant Teen.
