Has anyone here read Ikigami?
It isn't an anime but it's a great manga
It a sort of human nature exposition, there's very little violence but it still has an awesome concept and it's refreshingly human and down to earth.
The idea is that the Japanese government has launched a brand new law: because of the laziness and apathy of Japan s people it was decided that someone, daily and randomly, will be chosen and killed with a poisons capsule in order to bring to life again and wake up the others. The person elected will be warned with an ikigami (or deaths notice) and after this he/she will have only 24 hours left to live. What those condemned will think and do during this short time?
