Ikigami: The Ultimate Limit is dystopian psychological fiction. It's licensed by VIZ. I bought this volume used.
Review:
Content warning for this volume: on-page bullying and rape.
In this version of Japan, there's something called the National Welfare Act. In elementary school, all children are vaccinated against various diseases. Some of the injections include a special nanocapsule that eventually comes to rest in the child's pulmonary artery, where it ruptures on a specified day and time, at some point between their 18th and 24th birthday. No one knows who has a capsule inside them, and the goal is to make citizens value their lives more and increase their productivity. Any citizens who object to this system are immediately injected with a capsule.
Fujimoto has just started working as a messenger, one of the people whose job is to deliver ikigami, death papers. These are given to citizens 24 hours before they're scheduled to die, so that they may better appreciate their last 24 hours. The families they leave behind will be given a bereavement pension, unless they choose to spend their last 24 hours committing crimes, in which case there is no bereavement pension and the family must pay large fines as compensation.
This particular volume features the delivery of two ikigami, one to a man who was bullied so severely when he was in high school that it derailed his entire life, and one to a young singer/guitarist who has lost sight of what's really important to him in his quest to become famous.
