You wake up into the other world and find yourself in an old apartment where many monsters live. Not all of the monsters there are nice. Some of them are interested in you, a human that looks so out of place in the monster apartment. They are interested in tasting your blood, heart, etc. However, you meet Mr. Crawling, the sweetest monster of all. He follows you everywhere, crawling beside you to protect you from other monsters. He loves compliments and affection from you.
