**MEDIUM⁵** (五维介质, stylized MEDIUM5 and Medium5) is the brand, music label and title name for VOCALOID, Synthesizer V, and Synthesizer V Studio vocals created and distributed by the company Beijing Photek S&T Development Co., Ltd.. Currently there are five main vocalists released under this title: Xingchen, Chiyu, Shian, Cangqiong, and Haiyi as well as two supporting vocalists: Muxin and Minus.

## Concept

The concept behind the MEDIUM⁵ project states that a being known as ZERO who possesses the Metatron's Cube split herself into five girls, each of whom is represented by one of the five essential elements also known as the five *Platonic Solids*: Xingchen holds the star tetrahedron and represents the human body, heaven & earth, or aether; Haiyi holds the icosahedron which represents the water element; Cangqiong holds the octahedron which represents the air element; Chiyu holds the tetrahedron which represents the fire element; and Shian holds the hexahedron which represents the earth element. Minus' role in the MEDIUM⁵ cast, while currently unknown, holds the dodecahedron which represents ether, as well as Muxin who is noted to be a boy who likes to look up at the stars through a telescope.

## History

### 2017

Beijing Photek S&T Development Co., Ltd. CEO Ddickky noted in 2017 that people seemed to think that Xingchen was easy to manage because she was the company’s only VOCALOID. He mentioned that he wanted to try to "have five to take care of" to see how challenging it was to manage more characters and asked fans to "stay tuned". This seemingly hinted that there may be additional characters aside from Xingchen in the future. Later that month, it was mentioned that because Beijing Photek wanted to save money to produce content, some big news would be announced at Quadimension Live Tour rather than at a separate conference. This included new merchandise, new official art, and if there was time, new games or voicebanks. It was not specified if these voicebanks were for Xingchen or for any new characters.

### 2018

On January 5, 2018, a new female character was hinted and introduced as "Xingchen's younger sister", and would eventually be unveiled to be Haiyi.

The first usage of the label "MEDIUM⁵" (五维介质) appeared in 2018 at the time of Cangqiong's debut. From then on, any content featuring Xingchen or any of the other Beijing Photek characters would use the MEDIUM⁵ label. This would include demonstrations for other characters & vocals, albums, merchandise including figurines and other forms of media.

## Marketing

Various albums and merchandise have been released under the MEDIUM⁵ brand for the five singers. A game featuring the main cast was also in production known as *MEDIUM⁵ 2050* (五维介质2050). On March 11, 2023, Ddickky announced that the development of the game was suspended, citing issues relating to a financial situation and being unable to fulfill some of the previous funding agreements. Despite not being released, it currently has a 9.2 rating on bili games.

## Other Characters

Along with the originator ZERO, five additional characters were revealed to be part of the MEDIUM⁵ cast; their relation to the project is currently unknown. They have been confirmed to be a part of the *MEDIUM⁵ 2050* game.

### ZERO

**ZERO**, formerly known as **Quadimensionko** and **Xingchen ZERO** (星尘ZERO), is the patron saint of the planet according to the *MEDIUM⁵ 2050* game storyline and originator of Xingchen, Haiyi, Cangqiong, Chiyu, and Shian. She is the holder of the Metatron's Cube. ZERO is 16 years old and she is 160cm tall. Her birthday is listed as unknown.

In 2015, Beijing Photek S&T Development Co., Ltd. commissioned illustrator November to design a mascot for the Quadimension circle. Because of the name of the association being "Quadimension" and the team having a fondness for sci-fi themes, several requirements and explanations of the character's concept were discussed including:

* Having a science-fiction style with a sense of science and technology that looked suitable for flying around the universe.

* Having four ponytails, because circle is called "Quadimension".
	+ The Quadimension team thought that these two requirements were too big and slightly unprofessional, and questioned "What would Quad do?" without any explanation, and finally, the preview PVs of the two albums Quadimension 1 and 2 were released for reference.

After some time, the design was completed. It was stated that November watched the two album PVs and was more interested about the cubes that were flying inside the videos, so he looked into background information based on this element and pitched the ideas of the Metatron’s Cube and the starfruit. The design and initial concept was decided after hearing this. This would eventually lead to the creation of "Quadimensionko".

Around the time of VOCALOID production, Quadimension submitted this version of November's design in hopes of using the concept as a box illustration; however, the style and image were not approved, and the design was modified again, that then would become what now looks like Xingchen. It was stated that the team was uncomfortable with the new design, because the reason for the initial design not being used was not that it was not good enough. The director began thinking "There will be a day when we become stronger and have more autonomy."

Later the team discovered that Xingchen has "occupied" this position as mascot, and there could only be one Xingchen. The team questioned if this design is another version of Xingchen's "ZERO Form" design, or a scrapped concept. Quadimension noted they could not treat these two roles as one person however it could not be another unrelated character completely because it has a strong connection with Xingchen.

After another period of time, and a period of struggling how to handle this concept, MEDIUM⁵ came out. It was stated that she and Stardust are both one person and not one person, somewhere in between, representing the past and the present. The difference is the other sisters, and it also solves the problem of having five geometric bodies and elements.

From 2015 to present, ZERO has not been officially released, however Quadimension has not stopped improving her as a character. In addition to the few designs that have been released, it was reported that there are more modifications and adjustments during the design process. After four years, she was given the name ZERO, which means origin.

#### Role in *MEDIUM⁵ 2050*

According to the synopsis of the upcoming *MEDIUM⁵ 2050* game, the patron saint ZERO fought to the death and managed to defeat a powerful enemy; however, as a result of the catastrophe, the planet was devastated and became no longer suitable for survival. The seriously-injured ZERO decided to split into "Genesis Crystals" to restore the planet's ecology.
