This article is also available in Japanese: Read the Japanese version
Riko Solari is a streamer in VSPO! EN, the VTuber group VSPO!'s English-language project. Her name is written ソラリリコ in Japanese; her YouTube channel goes by "Riko Solari【VSPO! EN】". Her channel description consists only of "silly space girl!!" plus a kaomoji and an emoji.
She streams mainly in English, but go through her titles and one Japanese phrase keeps coming up: 「日本語勉強」 ("Japanese study"). Throughout this article, English in parentheses after her Japanese titles and lines is our translation; for song titles, it is the English her own titles give.
In this article, we set out VSPO!'s official profile alongside what can be traced through the videos left on her own channel. We do not fill in, by guesswork, anything that did not appear in the primary sources we checked.
Riko Solari's Profile: VSPO! Calls Her a "joyous entertainer"
Name: Riko Solari
Name in Japanese: ソラリリコ
Affiliation: VSPO! (VSPO! EN)
Height: 159 cm
Birthday: March 24
X: @rikosolari
VSPO!'s official member page has an entry for her, listed under VSPO! EN. It gives her height as 159 cm and her birthday as March 24.
Her official profile opens with "She’s a joyous entertainer who loves to make everyone smile." It continues, "Always mindful of her teammates in matches, her bright personality adds to the team." And it ends with "Always surrounded by snacks." The profile gets to her personality and her snacks before it says a word about her gaming skills, which makes it a friendly introduction.
In Japanese, her name is written as one unbroken word, ソラリリコ, both on the official site and in the fixed opening of her video descriptions ("Riko Solari (ソラリリコ)【VSPO! EN】").
Only the month and day of her birthday are published; her age is not given. We do not guess her age either.
As of September 25, 2026, her channel had about 70,500 subscribers. That is a number built up over about two years since her debut.
Debut in August 2024, on the Same Day as Narin Mikure
VSPO! EN began in June 2024 with the debut of three members. We cover how it started in our article on Arya Kuroha. The launch press release (in Japanese) that we checked did not yet include her name. She debuted about two months later. It seems fair to say she is a member who joined after the launch.
Her debut stream was titled "Is this thing working..?" and began at 11:00 a.m. JST on August 25, 2024. The debut schedule in the description lists Narin Mikure's debut stream one hour earlier on the same day. The two seem to have debuted back to back.
The description opens with "ALO!! I can see all of you from up here!!" Like a greeting from space, it is a fitting start for a "space girl".
The video that VSPO!'s official member page places beside her profile is this same debut stream. As of September 25, 2026, it had more than 40,000 views. Perhaps many people go back and watch her debut after the fact.
Apex Legends at the Center of Her Streams, Including Games with Her JP Senpai
When we counted her uploads by title on September 25, 2026, 101 of the 474 we could retrieve had "Apex" in the title. There were also stretches when she streamed VALORANT, Minecraft, and the Yakuza series.
Judging by their start times and lengths, most are archives of live streams. If you're new to her, starting with the archive of a game you're curious about seems a good way in.
Streams with VSPO! JP members remain on her channel, too.
This October 2025 stream is titled 「リベンジエペ！！！ふるぱ w/ エマ先輩 と べに先輩」 ("Revenge Apex!!! Full party w/ Ema-senpai and Beni-senpai"). Unusually for her mostly English titles, almost the whole title is in Japanese.
The description says 「楽しみ！！！！！」 ("Can't wait!!!!!") and lists the accounts of Aizawa Ema and Yakumo Beni. In April 2026 came another Apex stream, 「先輩たち大好き♥！！！ w/のあ先輩、すみれ先輩」 ("Love you, senpai♥!!! w/ Noa-senpai and Sumire-senpai"), whose description listed the accounts of Kurumi Noa and Kaga Sumire.
It's sweet to see her call the JP members "senpai". The "Always mindful of her teammates" side in her official profile may be something you can see in team streams like these.
「日本語勉強」 ("Japanese Study"): A Word That Keeps Appearing in Her Stream Titles
What stands out on her channel are the streams where she studies Japanese. By our count, 18 streams had 「日本語」 ("Japanese") in the title, from "LEARNING NIHONGO!!!" in October 2024 to 「日本語マイクラ！」 ("Japanese Minecraft!") in June 2026. It seems fair to say this is an effort she has kept up for more than a year and a half.
In February 2025 there was 「日本語じょうずになりたい！！！！」 ("I want to get good at Japanese!!!!"), and in March 2025 a stream where she took a Japanese test made by viewers. From April to May 2026, she streamed 「漢字を勉強しよう！！」 ("Let's study kanji!!") three times.
Looking at all her titles, those containing Japanese kana (hiragana or katakana) numbered 2 of 99 in 2024. That rose to 28 of 220 in 2025 and 31 of 155 in 2026 (through September 24). One could read this as her gradually using Japanese in more places.
That said, we have not watched these streams, and from the sources we checked we could not tell how well she speaks Japanese.
Her First Cover Was "Alien Alien", Plus a Six-Member EN Chorus
Her singing videos are on the channel, too.
Her cover of 「エイリアンエイリアン」 ("Alien Alien"), released on August 25, 2025, was her first: the description says "I sang my first ever song cover". The credits read "Vocals & Illust : Riko Solari"; she did the illustration as well as the vocals.
A self-described "space girl" starting her singing with a song about aliens makes for a fitting choice.
Covers of 「いますぐ輪廻」 ("Retry Now") and 「アゲアゲアゲイン」 ("Ageage Again") followed, and her name appears in the illustration credit of both.
Her December 2025 cover of "Snow halation" is a chorus whose description lists six VSPO! EN members' accounts as vocalists. As of September 25, 2026, it had more than 90,000 views, the highest of any video we retrieved. A video of the EN members singing together is probably something special for fans.
In September 2026, she also released a video singing 「アイデンティティ」 ("Identity") as a duet with fellow EN member Eris Suzukami.
Announced for an Event in the US, and Her 2nd Anniversary
A press release (in Japanese) issued by Brave group on June 20, 2025, announced "OffKai Expo Gen4", an event in San Jose in the United States. It named five EN members, including Riko, as performers in a game event where fans play against VSPO! EN. We checked only the announcement, not how the event itself went.
Even so, being named as part of EN for an event in the US where fans could meet them was probably a big moment.
On August 25, 2026, she held her 2nd-anniversary stream, "2ND ANNIVERSARY". The description says "I'm 2 years old now!!!!" and includes a link to anniversary merch. That was exactly two years after her debut stream. Celebrating the milestone with her fans was probably a happy time.
For the latest, check her X (@rikosolari) and YouTube channel. Her channel's links section also points to Twitch.
If you're curious, her debut stream might be a good place to start.
