Shinyou academy students die and one student is investigating this murder mystery - determined to catch the monster behind these murders.

You need to pay attention to the interludes to understand the whole story. That's what connects the whole story.

Eventhough it is a heavy theme for a high-school story , those who played the parts of Boogie pop, Manticore, Echoes, Nakao, Saotomekun, Nagi - all did their parts well.

Music was spooky enough but not satisfying for a spooky scene. The whistle seemed like a pleasant note which was ok - I liked the whistle tune. May be lighting adjustments also would have made some scenes more spookier.

I would have made the music a bit more spookier especially whenever the monster was about to devour its prey. It would have brought out the desired full fledged effect.

I liked the ending. You should definitely give this a try if you want to watch a bit out of the ordinary stuff.
