Sumire 16-sai!! ch1-End
Sumire 16-sai!! is an interesting manga in that outside of the initial premise, an old guy impersonating a perky high school girl with a doll, most of the actual setting and story tropes are rather straightforward, yet with the simple addition of this plot device the various overused concepts take a new light not much in the manga itself, whose characters react accordingly to the ridiculousness surrounding Sumire, but rather in the connotations of what her existence might mean, particularily when one could consider that the majority of beloved fictional female characters are, like Sumire, a doll controlled by some guy the author.
Yet, despite this rather unnerving vision of such characters, as one read through the manga, one can slowly realize that Sumire is for all intents and purposes a person, if fictitious one, and like all persons possesses her own personality and emotions, with her own influence on her entourage, which itself might either simply be the characters of a manga, or might symbolize the readers themselves. As such, her artificiality notwithstanding, Sumire is truly a "person" that lives and breathes life in the manga, all the while bringing her own twist to the typical high school setting.
In conclusion,
Sumire 16-sai!!, while at first glance seems like a mostly comedic manga, is a rather multifacetted work that can either entertain or unnerve the readers, but before all else presents a new view to the concept of characters themselves, yet it doesn't try to destroy or criticize said concept but rather help you appreciate the characters more, as well as the work of the author behind them.
