She has long blonde hair in a two-side up hairstyle and heterochromatic eyes, with a violet iris on her left eye and a blue iris on her right eye. She can also turn her left iris blue to match her right iris.

For her default outfit, she has a distinctive black hat with a plague doctor-inspired crow mask wrapped around it, paired with her mainly black coat with blue accents.

History[]

Background[]

On 29 June, Mugensho Record announced three new members: Memento Vanitas, Shuna, and Minami Izumi.[2]

Her YouTube channel was created on 12 June 2025. Her Twitter account was created in June 2025.

2025[]

On 4 July, Memento debuted on YouTube.[1]

On 27 July, she celebrated her YouTube channel getting monetized, as well as reaching 8,000 subscribers.[3][4]

On 11 August, she did an endurance karaoke stream aiming to reach 10,000 subscribers. The goal was reached after 3½ hours.[5]

Starting in October, her YouTube channel received a noticeable boost in subscribers, coming from her first-time participation in the MADTOWN GTA event.

On 23 October, her channel reached 30,000 subscribers.[6]

On 1 November, she celebrated her YouTube channel reaching 50,000 subscribers with a karaoke stream.[7]

On 3 November, her channel reached 60,000 subscribers.[8]

On 5 November, she tweeted that she wanted to do an endurance stream to reach 70,000 subscribers, but later that day her YouTube channel had already surpassed the milestone.[9] As a result, she adjusted the target to 80,000 for her endurance karaoke stream, reaching 75,000 by the time she ended after 3½ hours.[10]

On 7 November, she did the part 2 of her 80k subs karaoke endurance stream.[11] She reached the milestone after 1 hour, 18 minutes into the singing stream and kept going until 2½ hours had passed.

In early November, her channel continued to grow relatively quickly. By 11 November, she was listed at #1 out of 40 in Vmato!'s Weekly VTuber Subscriber Growth Ranking (for VTubers under 100k subs), ahead of fellow MADTOWN newcomer Hoshimiya Choco as well as Asakura Shino, now with 84k total subs.[12]

Events[]

  • From 1 October to 31 October 2025, Memento participated in the MADTOWN GTA event server organized by the Japanese eSports team Crazy Raccoon. Aiming to become a gang boss despite being a GTA newbie, she became the boss of the small-time criminal group Chinroutou (朕狼党), and they used the restaurant bar operated by Kenki as their base.[13][14] She was also able to demonstrate her singing at the in-game RiTunes Music Bar run by Rikka.[15]

Fans[]

  • Her fans are called "Chuuboku" (忠僕, Loyal Servants).

Relationships[]

Miscellaneous[]

Live chat etiquette[]

Memento's rules[]

  1. Do not mention "Memento Vanitas" in the streams of others! Or else you will be cast into hell.
  2. Do not include my name in your social media names; Instead, add (👁️‍🗨️🗝️) or "Loyal Servant" (忠僕), which is most welcome.💛
  3. Do not mention the names of other streamers when I am not talking about them! Else, you will fall into hell.
  4. Do not bring up personal topics or other topics unrelated to the stream! You will face damnation in hell, otherwise.
  5. Do not respond to spam and/or messages flooding chat, ignore them! If not, you will be sent to hell. You can help by reporting, blocking and ignoring them (I and the Mozzarella higher-ups will handle it.)
  6. Do not make comments that offend others! Users deemed inappropriate by me and/or Mozzarella admins will be muted, blocked and sent to hell.
  7. While streaming, I cannot read all comments out loud! But I can still see them. I appreciate your understanding.
  8. I will read superchats as much as possible, but I will not read names or words I deem inappropriate! I won't send them to hell.
  9. I am working on gathering many more loyal servants! Too much exclusive/insider talk amongst yourselves will result in your damnation!
  10. The Mozzarella administration is in charge of censorship! Muting and blocking are not related to my own likes or dislikes, but from their policies. If this befalls you, try to reflect a little before coming back!

Before commenting, do take a moment to breathe.💛
