For those who care, I posted my thoughts on Clochette and VN activism in general in this post ( http://forums.fuwanovel.net/blogs/entry/975-clochette-activist-vn-makers-or-just-endless-oppai/ ).  Now, a few issues with this VN.  Kokonatsu (Koko kara Natsu no Innocence) very much follows in the tradition of combining science fiction, fantasy, and/or science-fantasy elements in a charage with solid scenario design and writing to create an interesting whole.  In this case, it would probably be best to call it science-fantasy, because it involves time travel.

The protagonist, Hotaruzuka Arika, and Hotaruzuka Yuno are from 100 years in the future.  The Hotaruzuka sisters are traveling back in time to do their 'Promenade', which is essentially a graduate thesis, on Akio Village, whereas the protagonist got tossed in by accident.  The future they come from is basically one where all forms of recreation and individuality have been removed from society, almost by default.  Kids are born in tubes using genetic manipulation to get the 'best' part of the two 'donors' (only one is considered the parent), and people live by minute-to-minute schedules, using their 'Devices' to perform all sorts of tasks that maintain the future world.  As a result of this, imagination and sex drive are nonexistent in the future, save for a few people like the protagonist who were born naturally and raised in a 'traditional' environment. 

There is a lot more to it, but I'll leave it at that.  In the common route, most of the amusement in the story comes from Arika's difficulties adjusting to the inconveniences of the past, and most of the common route is taken up with getting to know and love the heroines and side-characters, as well as in comparing and contrasting the differences between the two eras through the protagonist's point of view.  In many ways, it is a classic case of a person who didn't fit in at home fitting in in a new setting, and the protagonist's unique multi-sided viewpoint is one of the reasons it is so interesting. 

Yuno is Arika's little sister, though their relationship is a bit more complicated than that (I'll leave it to yall to find out just how weird it sounds).  Yuno is, in opposition to her straight forward 'future' role-model student older sister, a natural trickster, who enjoys nothing so much as confusing others and dragging them along in her wake.  This doesn't change much when she gets together with the protagonist, but her point of view widens a great deal.  The drama in her path and its solution is interesting and well-detailed in the telling, and the actual after-credits epilogue was a nice conclusion, though the whole thing only scratched around the edges of what was going on behind the scenes in the main story. 

So far, this VN is proving that Clochette is still doing what it does best... combining activism/subliminal propaganda, good storytelling, ecchi characters and character designs, laughter, and generally interesting concepts to create a whole that is more interesting than the sum of its parts.  Now... on to Arika's path (I'll be doing the 'villager' paths after). 

Edit: There is also a definite undertone to the story that the mechanization and urbanization of society eventually led to a future where humans stopped caring about one another altogether, becoming so obsessed with rationality that they lost adaptability as a species.  This is important to the story in general, but it has parallels to social media, the internet in general, and 'connectivity' in general.  The nature of humans' instinctive need for close interpersonal contact is brought up subtly several times, and it gave me some food for thought along the way.
