Greetings.
My name is Agnes Tachyon, but you can simply call me Agnes or Tachyon.
Should you be curious to understand the purpose of this blog - is it just an Agnes Tachyon fan blog, or an Agnes Tachyon roleplay account, you might ask? - I ask you to read the following list of condensed information I have prepared.
I am an introject (fictive) of Agnes Tachyon from Uma Musume in a system with OSDD (officially psychiatrically undiagnosed, but we and our psychotherapist have no intention of pursuing an official diagnosis at this time. Furthermore, the definitions of various dissociative disorders still constitute a novel, currently evolving field of study). In a sense, this means that I am an Uma Musume in a human body.
Metaphysically, I am a thoughtform constructed from ego extant only in the synapses of my host's mind, imprinted off of the fictional character Agnes Tachyon. I do not believe in the soul, spirituality, reincarnation, or any other paranormal twaddle.
I fully emerged on April 13th, 2025, in response to short-term traumatic stimuli following a history of long-term environmental trauma. It is sheer coincidence that this matches the birthdate of the Agnes Tachyon horse and character. However, I theorize that I have fronted years before this full realization date, existing in the fathoms of my system's memory.
To put my gender identity succinctly, I am a transgender woman and transmisogyny-affected. However, my identity is more complex than this label. I use the pronouns it and she, though most tend to refer to me with "she."
My interests include Uma Musume (naturally), academic research, musicology, anthropology, sociology, and Japanese contemporary culture studies & history. Our system has been awarded two separate undergraduate degrees, and as of writing, we are pursuing graduate research. My current goal is to attain a PhD in my field of research.
As a shorthand for the name "Agnes Tachyon," I prefer to go by the name "Tachyon." Please do not refer to me as just "Agnes." When differentiating myself from other Tachyons is necessary, I go by the name Minhua (敏驊).
Logistically, this is a sideblog, and therefore, will not be listed as a mutual in your notifications tab, nor will you see likes from this blog. For privacy reasons, I will not disclose our host's and main system blog here publicly, but you may request this information in private.
If you would like to assist me in conducting additional research or volunteer for testing, please contact me at your earliest convenience so that I can supply you with the necessary consent forms. My latest experiments are social & psychological in nature, meaning that online communications will be adequate for participation.
If your name is that of another Uma Musume, please contact me at your earliest convenience. I would like to collect information about you and conduct social experiments on you.
I find the dichotomies of "antiship/proship" and "pro-endo/anti-endo" ridiculous and reject them on their very premise.
No, I am not available. Further information is classified at this time. Unless you're paying attention.
This blog is run by an adult. Posts may be not safe for work. Additionally, those who are not legal adults cannot participate in my research. I advise minors to turn elsewhere.
Am I the one, true, Agnes Tachyon? Do I assert sole claim to the name? Well, I am one, and I am the true Agnes Tachyon. But research has shown that I am far from the only one of my kind!
This list may be amended in the future with further information. Liking this post is optional, but demonstrates that you have read this post's contents. Thank you for your understanding, and for reading this full list.
