At the time of writing this manga, I gotta say that this manga is waaaaay unknown. 197 members? No, wait. SERIOUSLY?!?! This has got to be one of the funniest/weird manga series (that altogether becomes unique) I have seen. Story: Well it's pretty simple. A puppet Sumire comes into school one day and over the days inspires different people. At the end of near every chapter there's a "what happened to them in the future". So, after every chapter, we usually see Sumire back at square one in school, and the previous chapter character gone. Which is like Amagami SS anime arcs. Art: Not bad....Character:
Not much development really, but we could see Sumire's strengths and weaknesses (partly cos of the guy controlling her lol)

Enjoyment:
Well I enjoyed this partially cos it reminded me of Yuria 100 Shiki, where a lot of the expressions made by people shocked with Sumire and her abilities amused me. It would have been better if more was shed on the puppet master though.

Overall:
It's a good read, pure comedy, near no fan-service other than occasional panty shots but that's about it. A near no-nonsense comedy manga.

[Added after reading to chapter 11 of Sumire 17 and all 52 chapters of Sumire 16]

I just realised that there is an error with the relations. Sumire 17 was published in 2005 while Sumire 16 was in 2006. Thus, Sumire 17 should not be a sequel. In any case, Sumire 16 seems to be better than Sumire 17.
