When a group of children discover a strange cave at the beach, their lives are forever changed. Inside they meet a man called Kokopelli who seems to have a lot of advanced gadgetry. He invites them to participate in a ‘game' in which they play heroes saving Earth from fifteen giant monsters. To defeat the invaders, he will give them a powerful mecha of black armor. The children eagerly sign the contract, name their new weapon Zearth, and must now take turns to pilot it; but the ‘game' is in fact all too real and the consequences of battle become the stuff of nightmares. With no option to cancel the contract, is there any way to stop the game before it is too late for all of them?
Both manga share the same dark and depressing tone and deal with very similar ethical problems. While in Bokurano you have the giant robot and saving the Earth issue and in Ikigami is the Prosperity Law, they both center around individual stories of people who are expecting the same fate and try to deal with their thoughts, cope with despair and come to a resolve. Story-wise, Ikigami is more mature and episodic, while Bokurano seems more brutal, involving children.
The art is also somehow similar, not quite your pretty manga style, being more explicit and realistic in Ikigami.
So, if you liked one, you’d definitely –I can’t say enjoy- but appreciate the other.
Power corrupts, and absolute power corrupts absolutely. Top-ranked student Yagami Light is disenchanted with the world around him. Through a series of events, he comes into possession of the ultimate power over life and death: a supernatural "death note" which can kill nearly anyone at his whim. As Light sets off on a crusade-turned-killing-spree, investigators from a police task force try to stop the mysterious deaths - including Light's own father, a senior policeman.
Both series focus on cleaning up a society through the death of its members. While Death Note follows a vigiliante wishing to erase criminals from the entire world, Ikigami follows a government worker just doing his job-- telling people they are about to die. They have a similar philosphical feel and even the artwork seems similar.
