Whoa. These volumes feel too short, but they pack so much intensity into few pages! The antagonist entity comes back (of course) but the real meat in this volume is Hikaru's backstory (how she came to be an orphan, why she's so withdrawn, the drama of her father's death). And suddenly, she has friends (having saved one of their lives fighting the antagonist in the previous novel).
The antagonist entity is much more disturbing in this volume. We find that it's not just a blob/metamorphosizer, but that it engulfs its prey and imprisons them for awhile before digesting them. Interesting that it was able to imprison Hikaru in a mental prison for awhile. I felt the small panels/black and white format wasn't ideal for a creature of this magnitude - sort of needs a full-page spread, y'know? - but otherwise it was properly gross and frightening without being so horrific as to preclude most teens from reading it.
