Nineteen is a demon-crosser who can cross two kinds of demons, one is those who are obsessed with death and are about to die, and the other is about to become a demon and harm the common people. Generally, fallen demons are driven to a dead end and find it difficult to turn back. The demon-slayers not only have to save the demons, but they are also responsible for getting rid of the ones that cannot be saved and preventing them from harming the world. Sometimes they have to deal with the mess or take revenge for the demon being conquered. Therefore, the conditions for people to cross the demon are very strict. Generally, demon-crossing people have a heaven and earth to give birth to. When one demon-crossing person dies, another one will be born. Then he travels the world throughout his life and senses where there is a need to cross demons. Nineteenth is the nineteenth generation of demon-crossers. He originally thought that he would spend his life alone in the demon-crossers like the previous eighteen demon-crossers, but once after crossing the demons, he had an episode of mysophobia and went to take a bath in the river, but was spotted by a shameless rogue demon. From then on, the world of Nineteen was invaded step by step by this shameless monster until it was completely occupied.
She is beautiful and cold on the outside but cute on the inside and easily shy (that is, she is a tsundere) VS is black and shameless on the outside and only loves teasing, but is attacked by mysterious and powerful people
Intention: warmth and warmth in the world
