Tengoku Daimakyou

Youths live within a walled nursery managed by robots, where their lives seem orderly but hold promise and inquisitiveness. The area feels almost heavenly in contrast to the ruined outside world, which lacks machinery and is ruled by strange, powerful supernatural entities. Maru, supported by Kiruko, travels through the former Tokyo in pursuit of heaven. However, after an extended search, the idea of heaven may be less attainable and more of an unrealistic aspiration.
