Nirvana. The technology that united humanity into a cloud supercomputer. Every person can become a part of it. Thanks to Nirvana, the world is a better place. People found a cure for cancer, made the Moon their industrial zone and got a Delivery Line. But the most important thing is Plus. The same virtual reality that millions have dreamed of. Games indistinguishable from life and life like a dream. Unfortunately, high technology has deprived many people of work, and renting out your brain for hourly use to Nirvana has become the only income for most... But all this may disappear. Strangers that have appeared in virtuality are driving people crazy. And only artificial intelligence named Akira can protect those who sleep in Nirvana. Contains obscene language.
