Protecting your turf, keeping other guys from pawing at your girl, showing everyone who's boss--it's all in a day's work when you're a street thug...or a street cat!

    While parents mourn and authorities investigate, the students and teachers find themselves somewhere far away...somewhere cold and dark... a lifeless, nightmarish wasteland in which their school stands like a lone fortress. As panic turns to terror, as the rules start to fall apart, a sixth-grade boy named Sho and his friends must fight to survive in an alien world...

    Some eat silence. Some thoughtlessly kill. Some simply drive men mad. Shortly after life emerged from the primordial ooze, these deadly creatures, mushi, came into terrifying being. And they still exist and wreak havoc in the world today. Ginko, a young man with a sardonic smile, has the knowledge and skill to save those plagued by mushi . . . perhaps.
