Having been expelled from one such team, Team Summer A, Ango and Ryo roam the seas until they discover Team Summer B stranded on an island. Will things go more smoothly with this new team? Or will greed, deception and the lust for power become a deadlier enemy than the beasts and flora? The hellscape that was Japan is a lethal Eden, and the Seeds have brought their own serpents with them in the second part of 7 SEEDS!
