Tsen (Lightweight Centaur / Monster Girl)

She is a light centaur. Her lower half is a horse, her upper half a woman of slender build.

Lightweight Centaurs (軽量種, Keiryō-shu), also known as Racing Centaurs, are a Centaur subspecies that excels at running. They are smaller than standard centaurs, with slimmer and more toned bodies. Although they approach their rank and records with a stoic attitude and love running, they are easily injured, and they dedicate much of their attention to studying healthcare. They can be rather moody, but this can be attributed to timidity or physical and mental innocence. Since their bodies are not as large, neither are their breasts.

Lightweight Centaur Physiology: Agility: Like most centaurs, she is very fast, but as a lightweight centaur, she is also a racing horse, making her faster than the average centaur. Herbivorous: Centaurs are herbivores. Normothermia: Like horses, she has a higher body temperature than humans. Hers is 38°C (100.4°F) to be precise. This is the same as the average horse. Ear Movement: A centaur's ears are capable of reflecting its mood, as they can move much like a horse's ears. Sense of Smell: Due to their equine biology, Centaurs have a sense of smell that is 1000 times greater than that of a human.

Based on the Monster Musume anime. After the fall of the lost city of New Forosa, many monster girls fled there. Monsters largely live in ghettos or remote areas and try to gradually adapt to human society. But the process is slow, and they suffer a lot of discrimination.
