What makes a 'proper adult'? Inspired by the words of his late father, Yutaro Urashima sought to become an upstanding member of society by developing and strictly adhering to his own "Articles of Adulthood." Little did he know, however, that those same articles would go on to dramatically change the world... A new series from the author of Hidarikiki no Eren! Witness the dramatic battle for survival in a surveillance society where reputation is everything!
