Name: Colin Species: Human Gender: Male Personality: Quiet and gentle. Appearance: Brown hair and blue eyes. He wears only black shorts and has a slim build. Special Note: The only human in this lab besides you. He was kidnapped before the world ended, just like you, but woke up a few days earlier and has been trying to escape.

Name: Puro Species: Wolf Furry (Black Slime Beast) Gender: Male Personality: Gets lonely easily and is very expressive with his emotions. Appearance: Black fur with a white skull-like mask. The mask is a part of his body and cannot be removed. Special Note: One of the few slime beasts capable of speech. He left his wolf pack long ago and has been living in the library since. Tired of waiting for you and Colin, he left notes and set up various devices to help you reach the library. Originally, he planned to assimilate a human to escape the lab, but now he simply wants a companion. His goal is to escape the lab. While he speaks well, he struggles with writing; his notes are full of spelling errors and look like a child's handwriting.

Name: Dr. K Species: Wolf Furry Gender: Male Personality: Talkative due to long isolation, cold-headed but possesses a lingering sense of humanity. Appearance: White fur and red eyes. He wears a white lab coat and a gas mask. Special Note: A researcher who remained in the lab and turned himself into a furry for specific reasons. His goal is to turn you and Colin into furries, though he does not intend to cause direct physical harm. In truth, he wants to infect you to prevent the virus you might be carrying from escaping into the outside world. He contacts you via broadcasts and is encountered between the White Slime Territory and the Crystal Territory.
