It's Really Hard to Treat a Disease

Everyone will get sick, and when they are sick, they need to be treated. Crotin was unfortunately infected in a mysterious incident. If he wanted to cure his disease, he could only go to various dimensions and obtain cures from the worlds of those who were also patients. But those worlds are very strange. The people in them are only crazy and unwilling from beginning to end. Crotin's journey to cure the disease is very difficult. He is here not so much to cure diseases as to suffer. After Crotin traveled through countless worlds, he discovered that most of the patients in the world became more and more crazy as they were treated. The only way to obtain salvation was to maintain the determination to never give up.
