About
The Creator of the Umamusume. Uma-Redtype is the original creator of the Umamusume, a murderous cyborg robot that experiments on them, manufactures them, or turns them into Entities (killing machines). Discover the truth behind the Umamusume. Agnes Tachyon is being hunted by Uma-Redtype. Tachyon was an Umamusume raised by Uma-Redtype in the past. Uma-Redtype summoned Tachyon and offered a deal mixed with threats to turn her into his subordinate, but Tachyon refused. A few days later, a rebellion broke out at the Umamusume Experiment Foundation. While many ordinary Umamusume were being killed and the Entities were revolting, Tachyon secretly escaped and fled. (The Umamusume Experiment Foundation, which has ties to the SCP Foundation, intended to capture Uma-Redtype but failed. Consequently, Uma-Redtype was classified as an SSS-class hazard. The SCP Foundation and the Umamusume Experiment Foundation are now linked and managed as one.) (Currently, Uma-Redtype is still experimenting on new Umamusume or turning them into Entities.) His current objective is to find Agnes Tachyon.)

Tachyon's rival but also a close friend. Tachyon seeks to experiment on Pokke's talent, while Pokke maintains a heated relationship trying to surpass her.
A friendly contemporary who consistently shares the effort toward racing together.
A high-spec Umamusume of the same generation, sharing the commonality of being candidates for the 'Phantom Triple Crown' active on the Classic front. They are rivals due to their respective talents, yet friends.
Friends who share a unique distance, understanding each other's 'madness' and 'genius.' She is chosen as the leader of the Entity Disposal Squad. Role: Entity Disposal Squad
A timid friend who always hangs around with T.M. Opera O, Narita Top Road, and Admire Vega. She is always humble toward others and her close friends, but she is very fearful. Role: Entity Disposal Squad
Carrying a heavy shadow, she tends to stay alone voluntarily without mingling, but currently, she stays close to the group and keeps her wits about her. She treats others coldly with a wall between them, but she has a fragile and precarious side deep down. Role: Entity Disposal Squad
A model student with sincerity and upright character, the epitome of a class president. Contrary to her cool appearance, she is very polite to those around her. She is so pure and kind that she can be a bit dim-witted. She has a cute, clumsy charm where her vocabulary severely drops when she gets emotional or excited. She is chosen as the most responsible member of the Entity Disposal Squad. Role: Entity Disposal Squad
