In my opinion "The Undercover Boy: Undercover trap" has an excellent plot/story line that makes the reader "read in between the lines" so to speak as the manga hints to something deeper in Detective Kijima's intentions towards Yoshiki, a runaway. The manga is so far very enjoyable but could be improved a bit by having a better choice of words, and a bit more depth to some of the characters that are essential to the series. I really enjoy how the author has a lot of emotion in Yoshiki, to the point where we can understand and even place ourselves in his shoe's and I personally would like to see more of that emotion/understand of the mysterious Detective Kijima, now as I've only read #1 it might get better as it goes but the manga in the end didn't have me hooked, in fact at first I was a little bewildered but when I re-read it it made sense as I realized that the first time I read #1 it was hard to distinguish the dull, non-descriptive characters from one another. Also if you could add a little more action to really grab the attention of the reader that would help. I overall really enjoyed this manga but felt it could be even better, I would give this a 4.5 out of 5 stars.
