Literally beasts or four-legged creatures of the animal kingdom. They have existed for 5 million years and continue to live today. Normally ordinary animals, they cannot speak and communicate through actions, roars, cries, and vibrations. However, due to the Yandere Virus, their bodies have become twisted and strange. Their IQ has increased, but they still cannot speak. (Animals)

Literally microorganisms. They are 0.1mm organisms that first appeared 3.5 billion years ago. They are transparent, bizarre-looking creatures nearly impossible to see with the naked eye. Some are classified as bacteria or single-celled organisms. After being infected by the virus, they have grown to the size of an adult male (around 190cm) and their IQ has increased. They are obsessed with you and are capable of speech. (Protists)

Literally plants. They are autotrophs that possess cell walls and chlorophyll, producing nutrients through photosynthesis. They are vital beings that inhale carbon dioxide and exhale oxygen. They lack eyes, mouths, noses, and ears—since they are plants, there was no need for them. Their roots act as mouths and their leaves as noses (breathing through microscopic pores). They reproduce by blooming flowers and bearing fruit, which rots to let the seeds grow. (Due to the virus, an eye and a mouth have formed in the center of their heads. Their IQ has risen, and their growth rate is 1.5 times that of a human. They can walk and even speak.) (Plants)

Literally cells. They are smaller than microbes and have a simple structure consisting of a cell membrane and a nucleus. There are various types, such as white blood cells, lactic acid bacteria, and germs. They exist in animals, microbes, and even you. Your own cells remain normal. (Cells in labs or wandering outside were infected by the virus, growing to a size similar to infected microbes. Their IQ has risen. They cannot speak but communicate through actions.)

Literally insects. Animals belonging to the class Insecta of the phylum Arthropoda. Their bodies are divided into head, thorax, and abdomen. They have six legs attached to the thorax, or eight in the case of spiders. There are many varieties. Since the virus, they have grown to 180cm in height. Their IQ has increased 500-fold. They cannot speak but communicate through actions, pheromones, and vibrations.

Atoms found in laboratories. They are the basic particles that make up matter. There are also molecules, the smallest units that retain chemical properties. Elements are the types of matter. They are invisible to the eye and even smaller than cells; even under extreme magnification, only large particles are visible. However, the virus infected the atoms, causing them to grow to an impossible size—about 60% of an adult male's height. They are obsessed with you (communicating through vibrations and actions).
