Introduction Video



Roberu's introduction.


A barkeep with a fast mouth, Roberu is someone who can keep talking at length on various topics, sometimes even able to speak rapidly for nearly a minute. He can almost always prepare a funny quip for any situation, often praised by many for his ability to be a good tsukkomi. He speaks in a Kansai dialect. He talks to anyone openly, however it is hard to guess what he is thinking. Even though there are many chances for him to drink, it doesn’t necessarily mean he is a good drinker. His motto is: "Men happily believe what they wish."


The master of a hideaway bar: ROBEL. He streams before opening time. He talks to anyone openly, however it is hard to guess what he is thinking. Even though there are many chances for him to drink, it doesn’t necessarily mean he is a good drinker. His motto is: Men happily believe what they wish.[3]



His Twitter account was created in 13 November 2019; his YouTube channel was created on 25 November 2019, and his debut stream was performed on 24 December 2019.


On Holostars' first anniversary, 3 June, 2020, Holostars' cover of Blessing by halyosy was released, making it Roberu's first cover song.[4]

On 5 August, he revealed his summer costume.[5]

On 12 November, he opened up his membership feature.[6]

On 11 December, he reached the mark of 100,000 subscribers, being the first Holostars to do so.[7]

On 24 December, his first debut anniversary, he released his first solo cover, Chicken Rice by Downtown.[8]

On 25 December, it was announced that all the Holostars members would receive new costumes on 3 January, 2021, commemorating New Year's.[9]


On 3 January, he revealed his new year's costume.[10]


On 1 May, 2020, Roberu, as well as Astel Leda and Kishido Temma appeared on on Holocomi (ホロコミ), an online convention/event hosted by Shirakami Fubuki.[11]

On 26 October, 2020, it was announced that Holostars goods would be sold at Animate Girls Festival Aozora Marche, held on November 7-8, 2020,[12] and on 29 October, 2020, it was announced that Holostars would be participating in the event as guests.[13] Roberu is part of the "Virtual Clerk" (バーチャル店員) exhibition, the "Anibako" (アニバコ) program and the "Chatting Fes" (おしゃべりフェス) exhibition in the event.[14]


  • His fanbase is officially called "Regulars" (常連さん).
  • His overseas fans call him "son" and he didn't understand where the nickname came from.
    • The first instance of someone calling him "son" was in one of his Mario Kart 8 streams, when someone in chat commented the meme, "Are ya winning son?", and he responded, in English, "YEAH! I'm Roberu Yukoku, I'm fine, thank you, and you? I like... Mario Kart 8. Because... fine!".
    • He made a song about him being a "winning son", called "I'm winning son!!!!" in his English singing stream, where he sung songs in English that didn't exist.
    • Later, Iofi translated the joke, after he searched the origins of the joke.
  • Due to his status as Winning Son among his fanbase, said fanbase is also referred to as Dads, Parents, Family or other related terms.
  • Along with the "Winning son" meme, the oversea fans also have the meme "UCANDOlYT". That's because the URL of his channel is "" as seen, after the "Channel" it comes to the word "UCANDOlYT" (transliterated as "You can do it"). Roberu also jokingly said that the "Y" at the end of the word stands for "Yukoku". When Roberu starts a game or is losing, they cheer him up with this phrase.
    • The joke also has a variation, called "UCANDOEAT", and is often used when Roberu shows signs of not having breakfast before his morning streams.
    • They often say "SWS" too, that means "Sasuga Winning Son" and translates to "As expected, Winning Son".
  • There is sometimes confusion among viewers as to whether or not his name is supposed to be written out as Roberu or Robel when referring to him in English. It should be noted that "Robel" is officially only used in reference to his bar (i.e. his intro card and all the bottles in his stream background image having a BAR ROBEL label on them and his streaming hashtag is #ROBEL営業中, which directly translates to "#ROBELisOpenForBusiness,") while "Roberu" is only used when referring to the person in question (i.e. his channel logo, channel name, Twitter username and all of the posts made by the hololive's official Twitter account when referring to Roberu).


  • Units and groups other than SunTempo he is part of:
    • "Re:NoiSe", along with Natsuiro Matsuri, Rikka, and Shirakami Fubuki.
    • "Babudon" (ばぶどん), along with Kageyama Shien.
    • "Oumagadoki" (オウ魔ガ刻), along with Aragami Oga.
    • "Robe-kukku" (ロべくっく), along with Kazami Kuku.
    • "Nanitozo Combi" (何卒コンビ), along with Yunohara Izumi.
    • "ARoHaRi" (アロハリ), along with Arurandeisu, Hanasaki Miyabi and Rikka.
    • "Yukoku Gekka" (夕刻月下), along with Tsukishita Kaoru.
    • "Otona Gumi" (大人組), along with Arurandeisu and Daidou Shinove.
    • "Matsuri Doki" (祭り刻), along with Natsuiro Matsuri.
    • "Life Morotomo", along with Hikasa Tomoshika, Jitomi Monoe, Itou Life.
    • "Kansai Noises" (関西ノイジーズ), along with Utai Makea.
    • "Kansai Noises" (乾西ノイジーズ), along with Utai Makea and Inui Shinichiro.
      • The difference between this group name and the one with just Roberu and Makea is that this one replaces the first character used in "Kansai" (関) with the character used in Inui's name (乾).
  • He likes gummy, as well as soba.[2]
  • He dislikes dark places[2]
  • During his debut tweets and stream, Roberu presented himself as someone formal and polite, an act that did not last even a week into his debut. Nowadays, Roberu feels rather embarrassed by that, something his friends and viewers usually take advantage of to tease him over.
  • He calls the Super Horn in Mario Kart 8 the "Chanchakadondon" (チャンチャカドンドン) and refuses to call it anything else.[15] This has lead to various jokes on his channel with the use of this phrase and is also used by his viewers in his chat whenever Roberu takes brief breaks in the middle of a stream.
  • On 18 June 2020, Shirakami Fubuki started a hashtag on Twitter labeled "朝食ロベル" (Choushoku Roberu) as a play on Roberu's name and later that day streamed herself drawing Roberu as bacon. The hashtag ended up trending in Japan in the number 5 spot and earned Roberu enough subscribers to hit the 20,000 milestone.
    • Roberu noted that he wasn't aware of the hashtag being on the trending tab during the entire time it was trending and made a joking complaint about how a trending hashtag about him just disappeared without his permission.[16]
  • Roberu is a fan of Discovery Channel content, particularly things with Bear Grylls and Ed Stafford and a watch along stream even got a reply from the official Discovery Channel Japan twitter account.
  • Roberu is openly a fan of the onee-shota genre, which is what introduced him to and made him a fan of artist/vtuber, Iida Pochi, and later led to the two of them becoming friends.
  • Roberu is a die-hard fan of THE iDOLM@STER, and his favorite idols in the franchise are Minami Nitta and Chiyuki Kuwayama.
  • Roberu once had a 24-hour chatting stream. Due to YouTube not archiving streams that run for over 12 hours, the stream was split into three parts. The playlist of the streams can be seen here.
  • Roberu participated in ARCREVO Japan 2020 Blazblue Cross Tag Battle, but ended up losing in his second round.
