It's really refreshing to find a school-life comedy manga that isn't tainted by silly romance or pointless ecchi, and Sumire 16 Sai!! is definitely one of those rare gems.
The protagonist has one of the most original characters designs I have come across in a shounen manga to date, and his / her presence makes anything that would normally have been an average, slightly amusing situation, incredibly hilarious.
There are even some surprisingly touching moments in the story, and it was rather heartwarming to see how Sumire wins over the select few people who have the good sense to see him for his true worth without been wrapped up in thoughts of his odd hobby. A line from the one of the characters says it all; "People and places all change so fast, but in this city there is one person who will never change. And I think those few who're in the know are very fortunate"
I experienced a brief moment of alarm when
the female ventriloquist and her puppet made an appearance, fearing that the mangaka would be tempted to take the easy way out and turn this story into a yet another romantic comedy. Thankfully, I was soon proven wrong. While it is quite obvious that Sumire and Sakura are kindred spirits, it is equally obvious that they have no romantic feelings towards each other.
The two last chapters were particularly well-done; Nagayoshi Takeru made the right choice in abandoning his usual brand of silly humour for the sake of a simple, bitter-sweet conclusion.
A word of warning to potential readers; this is most definitely a shounen manga. It is by no means realistic, and childish optimism is a predominant theme throughout. Those who cannot bear to see forever-positive-and-cheerful characters would do well to steer clear. However, if all you are looking for is a good laugh, Sumire 16 Sai!! is a choice you won't regret.
