PiaPiUFO

PiaPi is a slime alien VTuber in a human suit and princess of Planet Poppipo. According to their lore, they got lost in space, ran out of fuel crystals and is now scraping by as an idol that is orbiting Earth. As it stands, and no records can be found, there has been little else to confirm whether these self-proclamations are true, but until such otherworldly sources can be obtained it will not be pursued any further.

In her human idol form, she has turquoise hair with pink highlights and yellow star hair ornaments - the yellow accents and star theming are repeated throughout her costume. Her hair is bunched up to either side, as well as being braided. She has vivid pink eyes and purple 'ears'. She also has a skin fang and a purple tongue.

Their outfit is primarily composed of their idol dress, which is primarily turquoise and white with prominent star motifs in yellow. The dress hugs tight around their midriff, but blooms out into a flowing pleated skirt.

She wears white arm warmers with bracelets that alternate yellow and green. Matching that, she wears asymmetrical leggings— her right legging going to her thigh, and her left only going up to her knee. These leggings continue seamlessly into futuristic heels, where the 'heel' itself is composed of floating multi-colored blocks. She also has a band of turquoise fabric around her left thigh, with four-pointed stars.

Over each shoulder and around each ankle, they have two floating bands of color - one purple, and one turquoise.

In her slime form, she is a roughly hemispherical turquoise blob of slime, complete with slime 'drips'. In this form, her eyes are simplified in a sketch-like manner with no pupils. She retains her 'skin' fang, her purple mouth, her eyebrows, and the heart-shaped 'ahoge', but all else has receded.

In this form they are slightly transparent, and as such their core is visible - a purple organ the shape of a rounded star.

Pia's 3.0 model debuted a combined human and slime form. That is, it is both humanoid in shape and slime in substance. The humanoid slime form can wear a "skinsuit" to have flesh-colored human-like skin and can fit humanoid clothes, or either can be taken/toggled off.

On 22 February, their debut original song 'Gravity' released, which immediately solidified their position as an idol and gained fans who dubbed themselves 'Pia-Pickles.'

On 4 March, they released cover of a Japanese song called 'Life is full of Dreams/Jinsei wa Yume Darake' (人生は夢だらけ) by artist 'Sheena Ringo' (椎名林檎).

On 22 April, Pia released a cover of KING by Kanaria as a 400 sub celebration for their YouTube channel.

On 23 June, Piapi's first Twitch stream took place, where they now principally stream, and their VTuber Q&A introduction video was released within the same week on the 27th of June.

On 1 July Piapi became Twitch affiliate.

On 7 July, Piapi attempted an endurance stream that lasted a full 24 hours, the day of her birthday.

On 28 August, Pia's appearance redebut was revealed in a bikini form in a 'Beach Episode' event stream. Exactly a month later on 27 September, during a stream titled 'Laundry Day', the appearance change was made permanent to positive reception.

On 15 October, PiaPi's Twitch channel reached 1,000 followers.

On 19 January, Piapi reached 1k subs and subsequently became a YouTube partner.

On 4 February, the official YouTube partner celebration event stream took place.

On 27 May, Kawa Entertainment announced they had hired Pia as part of their first wave, "Luna". Her debut under Kawa was announced for 3 June.

In the summer, Piapi was both a guest at Offkai and ANIME EXPO and also was in a concert sponsored by Sony Mocopi.

On 8 August, PiaPi debuted her 3.0 model, referred to as "New Drip." This was first model not drawn by PiaPi herself, being illustrated by SS1, and rigged by regular Kurono Gomi and. Stylistically, the new outfit features sporty, colorful, techwear-inspired fashion.

She ended the year with a 2023 wrap-up summary.

On 10 January, Pia's agency Kawa Entertainment dissolved the talent management portion of their business. Kawa CEO Pidge stated "I thought I could do it better," and "our talent side has always felt like we never quite reached the goal I set out to." Pia continued as an independent VTuber, and remains friends with the staff to this day.

On 25 January, via chat funding, PiaPiUFO bought guinea pigs Churro (brown) and Peppa (white with black spots) at a local pet shop and into her home. She would dub them her "potatoes".

On 7 February, she reached 10,000 followers on Twitch. This marked a period of growth coinciding with her participation in a series of Palworld events, including an additional 2,000 follower gain during the Twitch Rivals event of 22 to 23 February.

On 1 March (JST), PiaPi began an uncapped "3YR CELEBRATION DONOTHON" event. In an underestimation of her own, she used the same timer increase values as her much smaller 2022 subathon, resulting in the event continuing for several months instead of days. The donothon finally ended on 10 August.

On 3 March, she finally reached Twitch partner status.

From 31 May to 2 June, PiaPIUFO attended Offkai Expo. Although not a Featured Guest like the year before, she attended various fan events. On day 2 she held a "PiaPickle Pizza Piarty" where she showed up in cosplay of herself, made borax slime, and served pizza, Japanese Kitkats, and Ole Smoky Tennessee Moonshine Pickles. On the last day, PiaPi would again don her cosplay and hold fan meet and greets beside the Vite Ramen booth. The very long line for the meet and greet would exit the booth and snake its way up some nearby stairs.

On 18 December, she reached 20,000 Twitch followers.

On 26 December, she reached 10,000 YouTube subscribers. This sharp rise in subscriber count was attributed to her appearance as opening act for the Fantôme Thief's Revenge concert on 14 December, gaining around a 30% increase in subscribers in 12 days. Following the event, which represented for Pia a return to being a singer and idol after experiencing long-term vocal injuries at a previous job, she would restore "VSINGER" to her social media profiles.

She ended the year with a 2024 wrap-up summary.

On 3 May, PiaPiUFO streamed the debut of her chibi model, colloquially known as PiaPi #83, ChiPia, or Smoll PP. The model features a bald toggle (with optional Aang from Avatar: The Last Airbender arrow), a cross-eyed toggle, an alternate worm head, and just about any emotion you can think of. The mamas for the model would be cinfulnoot and rqmaddie, and the papa Kurono Gomi.

On 20 May, she reached 20,000 Twitter followers.

On 22 July, PiaPi revealed that she had signed with US-based agency VShojo, and was originally planned to debut with the group later in the year. Following allegations that the company failed to pay over $500,000 in charity donations, PiaPi announced her departure from the company. A collaboration stream was subsequently announced including would-be genmates Beribug and Tori Oriane. The group has since announced their name as the BEASTIEZ.

On 5 August, she reached 30,000 Twitter followers.

On 9 August, she participated to a special idol themed concert in Washington D.C called Idol Harmony. She performed alongside: Utano Pandora, Pengy, Phoebe Chan, and Keekihime.

On 14 August, she reached 30,000 Twitch followers.

On 16 August, she reached 20,000 YouTube subscribers.

On 12 October, it was announced that Pia along with 14 others were selected to become Twitch Ambassadors. Later that week, as an official Ambassador she would be flown to Twitchcon 2025 where she would participate in three of Twitch's Creator Camp panels and hold meet & greets.

In October, Pia was ranked by Vmato as #32 fastest growing Twitch VTuber for the month.

On 10 December, Kairyu Crocodile aired her introductory animation on YouTube and thereby formally joined the BEASTIEZ. The group's first full 4-person collab stream and their hit MONSTER cover, proved to be some of Pia's most watched content so far with 170,000 and 140,000 views respectively in their first 4 days on YouTube.

On 18 December, Pia reached both milestones of 40,000 Twitch followers and 40,000 YouTube subscribers. Three days later on 21 December, she was ranked by Vmato as #1 Twitch follower growth and #2 YouTube subscriber growth for the week.

As usual, she ended the year with a 2025 wrap-up summary.

On 1 April, the four members of BEASTIEZ debuted their Kawasona models. Styled after the popular Japanese web series Chiikawa, Pia appeared in her slime form as a chibi-size happy, bouncy, little blob complete with a toggle-able Sonic the Hedgehog costume and her trusty Stick. The model features art by Nonomiya Mikan and rigged by Komi Clearly.
