The world is a very strange term. It traps humans and other creatures, but it absolutely does not allow them to betray themselves.
There is a kind of people who have no sense of pain, have endless lives, and can understand any human emotion, but cannot possess it. They are said to be human but not. They are called murderers.
Kill all those who try to collapse the world and destroy the destiny. Walking in every world, regardless of good or evil, regardless of the reason, just kill when it is necessary. This is the killer!
