Cirra

"'To truly know the workings and meanings of Aether, one must confront the dark truth that their sense of isolation to the universe and self is nothing more than an illusion. It is the darkness that is reality, the void after death, for once our time is up, we will truly lose our selves and return to the universe without the illusion of Aether and see its true form.' -AS-8"

AS-8 "Electromagnetic Fumo" is an anomalous, sentient, Fumo-branded plush of Cirno from the Touhou series. They communicate in Class 5 encrypted radio waves and require a radio for them to communicate, despite not having any electronics embedded into them.

Known to be a philosopher and an asshole

Personality
They are known by a few people for being a bit of an asshole, especially to Adam, who found them and cracked their code. While they can pretty much go anywhere, they like annoying people so they usually stick to a few people. They don't believe in a "self" per say, they try to distance themselves from the concept of sentience and free will. They don't refer to themselves as a being, as they believe that the self and ego is only a perversion of reality. Which is why they don't really have a name, so you can call them anything and they only regard it as a meaningless gesture. Always talks in the third person

Philosophy
While it doesn't look like much, this doll knows more than they let on. Knowing things that many people don't even know about, such as souls and Aether itself. It believes that Aether itself is the reason as to why things can think in the first place, and that souls, the ego, the self, is a puppet's strings. That nobody has any free will and everyone is under the control of whatever Aether is, and the only reason why people don't realize that is because the self gets in the way, as truely believing that you are no different to the rest of the universe causes people to go mad. A determinist and a nihilist.
