Check out previous reviews of Kashimashi vol. 1 and Kashimashi vols. 2 and 3.
After the story wandering around uncertainly for a while, Kashimashi vol. 4 finds it metaphorical feet in the revelation that Hazumu's near-death experience of volume 1, the one him to a her, was fated. Fate is not something that can be denied, and Hazumu's death is approaching once again. With that sort of ticking clock in the background, suddenly the characters have something that drives them, so that things matter. True, there is a bit of soap opera business where all of the characters know that Hazumu has a month left to live but no one knows that everyone else knows, but it prevents everyone descending in maudlin crying. I do wish that the characters had handled the revelations at the end of the third volume a little better, especially the potential 'cure' for Hazumu that was introduced at the end of that volume that wasn't really followed up in this one. Overall, the introduction of the ticking clock has pushed the series back up in the 3 1/2 stars category.
The Kashimashi vol. 1, vol. 2, vol. 3 and vol. 4 are all available from Right Stuf, Intl., an online retailer specializing in anime and manga.
