A powerfully imagined vision of the future from Taiyo Matsumoto, creator of the Eisner Award-winning Cats of the Louvre and Tekkonkinkreet.In a world where most of the earth has become a harsh desert, the Rainbow Council of the Peace Corps has a growing crisis on its hands. No. 5, one member of a team of superpowered global security guardians and a top marksman, has gone rogue. Now the other guardians have to hunt down No. 5 and his mysterious companion, Matryoshka. But why did No. 5 turn against the council, and what will it mean for the future of the world?The old allegiances and friendships have been broken and the Rainbow Brigade now faces disbandment. No. 5 has eluded or killed every member of the Rainbow Brigade that has come after him so far, but now No. 3 closes in on him and is determined not to let any sentiments for his former comrade cloud his judgment. Elsewhere, No. 1, missing for over a month and struggling to understand what to do with his power, heads for a fateful meeting with No. 2.
