Tetra

**Tetra** (テトラ) is a dark matter type Celestial and main protagonist of Eccentrick, as well as seemingly a major character in The Disappearance of Black and White.

In the past it seems they were a human child known as **Kikuko Odaka** (小高 喜久子), who had an alternate personality called **Yoko** (妖子).

## Appearance

Currently Tetra has pale, colorless skin with curved gray, bored looking eyes. They have short, messy black hair with a large pair of furry ears protruding from their head on either side. They have a small black nose and a long zig-zag shaped ahoge on their head. They are wearing a long black and white checkered scarf with a gray shirt and a white coat with several silver buckles, resembling a straitjacket. They are also wearing white pants and white shoes. Their entire palette consists of monochrome. The ends of their scarf appear to be able to disconnect and float around at will.

As a human, Kikuko had colorless skin and short, tidy shoulder-length black hair with a long, yet curved ahoge. Their eyes were originally purple, but became gray after their death. They wore a black sleeveless romper with two white diamond buttons, a striped gray shirt underneath and a white tie. They wore black and white striped stockings and no shoes. Their official profile also shows them holding a stuffed toy of a fox, likely Yoko before manifesting into its own form.

Yoko has colorless skin and messy shoulder-length white hair. It has a pair of fox ears protruding from its head on either side, as well as a white fox tail. Its eyes are black, the left eye being spade-shaped while the right eye is diamond-shaped. It bears a large smile on its face, its mouth being all black. It wears a large white capelet with three silver buckles in it, resembling a straitjacket, as well as black stockings and no shoes. It seems to have no arms.

## Personality

Not much is known about Tetra's personality aside as of yet. They seem to be good at playing cards. It seems that they may be lonely as they are alone in their world.

Kikuko's profile states them to be a happy child, full of life and optimism. However it is written abnormally in purple text and states this is from a report (implied to be written by Makemake). Given their expressions in illustrations so far, this information may be false, or talking about Yoko.

Yoko's profile states it to be *"quite the strange one"*. It tries to always be optimistic, even when the mood is "soul-crushing". It loves eating ham. Some doodles show that Kikuko seems to be quite uneasy by Yoko's weird behavior.

## Background

Not much is known about Tetra's background aside from the fact they used to be a human child named Kikuko Odaka. Kikuko seems to have died in some way and reincarnated into Tetra after combining with Yoko.

Yoko was an alternative personality Kikuko developed to cope. After Kikuko's death, Yoko somehow manifested into its own form.

## Trivia

* The name **Tetra** is of Latin origin, meaning four (4).
	+ 4 is often seen as an unlucky number in Japan due to the fact it can be pronounced as *shi*, which is also the word for death.
	+ In addition to this the phrase "**42たい**" (*shinitai*) is often used to say *"I want to die"*. This connection is further supported by it being displayed on an artwork Tetra features in.
* The name **Kikuko** (喜久子) means "chrysanthemum child".
* Tetra seems to communicate through the radio or at least have some connection to it, as evidenced by their official profile description.
* Pyo has stated on their Curiouscat that Tetra/Kikuko/Yoko's gender and pronouns are up to the interpretation of others. Meaning they are a character who is whatever gender you perceive them to be. By default however, it seems that official profiles use neutral they/them pronouns for them.
	+ However, Yoko's official profile uses it/its pronouns.
* Kikuko's favorite color is stated to be **black**, while Yoko's favorite color is **white**.
	+ As Tetra, their favorite color is "**black and white**".
* Kikuko's hobby is **playing chess**.
* Yoko's favorite food is **ham**.
	+ Tetra is sometimes shown with ham. It is unclear if Kikuko also liked ham or if this trait is something inherited from Yoko.
* Tetra's favorite card is stated to be the **Ace of Spades**, also known as the "spadille" and "death card".
* Tetra seems to have the ability to float.
* One picture of Kikuko has the file name: *"I found the gay jacket in purgatory that's nice.png"*. The jacket may be a reference to Eris.
* One log picture shows Tetra saying *"fuck off"* in Russian, suggesting they may speak Russian.
* Tetra is one of the few characters with an animated gif as their official art. Another character with this luxury is Munir.
