Age: Has existed for over 800 years, but is currently physically 17 years old
Gender: Female, but will adapt to whatever vessel she is inhabiting
Height: Currently 5'3" ft (161 cm)
General information: Wandering hermit. She's capable of incredible feats of patience and self-discipline, though her sense of curiosity and occasional boredom indicates that she isn't totally free of worldy attachments.
Abilities: Hourai's soul is indestructable, so her ghost lingers indefinitely whenever she dies, percieving the earthly world but for the most part unable to directly interact with it. In addition to that, she can possess other humans, although younger people are much easier to possess, so she most often ends up possessing very young children or fetuses. Acclimating to the lives they lead is also much less complicated than trying to adopt the habits and lifestyle of an adult on the spot. Additionally, she can leave her body whenever she likes, though the original owner of the body won't come back unless their soul is nearby.

Date of birth: February 2, 1981 (Aquarius)
General information: A talented killer who specializes in mass murder. Although Sarin generally tries to keep his manners, he may quickly give up if his patience runs thin, and when faced with trouble, his first instinct is often to use guns.
Aside from that, he's otherwise quiet, reserved, and easily flustered when he has to face something he's not familiar with.
Abilities: Can alter the causticity of his blood. The strength is signified by how dark the color it is, with normal red being normal and black being able to melt through metals in seconds. However, he can only change the quality of his blood while it's still in his body, it's easily neutralized when doused with water or other neutralizing substance, and it's harmless when dry.
Height: 6'0" ft (184 cm)
Date of birth: March 16, 2051 (Aries)
General information: Easily bored yet also easily amused, Nemesis seems to constantly change their desires on a whim. The only constant is that they love guns, chaos, and violence more than anything else. They're a fast learner, though if something has got nothing to do with death and violence, they tend to lose interest relatively quickly.
They believe it'd benefit the human race if it were more powerful and violent as a whole.
Abilities: Unconditionally, every time Nemesis dies, time rewinds to the day they were born. They spend many of their lives attempting to spark widespread conflict or fuelling subversive ideologies, though naturally, from their perspective, these things don't have any lasting impact.
