Suicide Helpers, who exist in another world, are the 'helpers' who help to give a fast, unpainful, and fancy death to the people who want to kill themselves. You can summon them with a card and when you collect four suicide helpers, you can get a special card called 'Reset Button'. The story of started with my experience - the moment I was suffering from depression -, the moment that I always dreamt about peaceful and unpainful death. And also I want to ask a question to other people about the true meaning of 'suicide' or 'death'. In modern society, people tend to use the phrase like 'I want to die so easily. My question is: so if you're in the world in which those 'Helpers' are available, do you really want to choose death? What is the meaning of 'death' in this world?
