Kuzuha's introduction. (no longer available)


He is an extravagant NEET vampire gamer and has now been living with a pet pig that takes care of his belongings.[2] He is a whimsical and carefree vampire that has a habit of getting carried away. He is a cash-strapped vampire with a strong love for money.


Despite initially debuting as a reserved and suave vampire, the current Kuzuha is a loud-mouth and entertaining individual. He is very expressive when playing games, often shouting or boasting his own genius. He has a characteristic drawl and casual way of speaking which is often parodied by other livers. He is quick to become jokingly aggressive and confrontational to fellow livers, and often says or tweets off-beat things.

However when collabing with other livers he is known to be infamously shy and awkward. His first collaboration with Sakura Ritsuki sparked the birth of what is known as his "Weather Deck", where he attempts to start a conversation by asking about the weather. Though after some time, these collaborations would get more chaotic and less awkward as he gets closer to them. Kuzuha would also sometimes give valuable life advice to his viewers.[3][4] Truthfully, he seems to be a hesitant and modest individual; He often talks about his uncertainty in his own skills and working towards improving himself [5][6] Kuzuha is perceptive to the feelings of others and can easily read the room. He once comforted Yuuki Chihiro in his own way when she cried on stream.

Despite being a vampire, he easily gets scared when playing horror games and would always try to stall for as much as possible if given the chance.


Kuzuha has striking white hair of differing lengths across his different avatars. He has pale skin, wide upturned scarlet-red eyes paired with dark eye-bags, and a small mole under his left eye. Though rarely seen and not quite visible in his current outfits, Kuzuha also has a small mole on his right collarbone, and another one on his right arm. Being a vampire, Kuzuha has a pair of sharp pointed fangs, very long claw like fingernails, and pointed ears that have multiple piercings. Kuzuha has been seen wearing multiple differently-styled clothes.

In his current outfit, Kuzuha has his not particularly styled mid-length white hair with a right-sweeping fringe. He wears a black zip-up turtleneck tracksuit with his signature red bat logo on the right side and a white stripe lining from his shoulders to his sleeves. The tracksuit has slits on the back near the waist so that his wings can open freely. Under it is a dark wine red sleeve length V-neck with a cross design on the neckline. He wears this ensemble either bare-foot or with lounge slippers, and with white wide-leg lounge pants that are slightly longer than his legs.



Kuzuha made his YouTube debut as an independent VTuber on 8 March 2018. After being personally scouted by Ichikara Inc., he officially joined the 3rd batch of NIJISANJI Gamers (formerly) and received a new Live2D character model on 30 July 2018.[7][8] Before joining, Kuzuha was planning to join NIJISANJI as a trainee but after he saw Kanae and Akabane Youko passed the audition, he decided that he will also join NIJISANJI Gamers.

    • The unit's name was a fan suggestion among many, with the idea that both Kanae and Kuzuha like the color black, and from there, their name was made from the Japanese word "" (Kuro, Black) and the French word "Noir" (Black), making "KuroNoir" and later, "ChroNoiR". The name would also mean "黒黒" (Kuro Kuro, Black Black) in Japanese and it's initials would be "KK" for Kanae and Kuzuha's name.

Despite this, Kuzuha mentioned that he is the type of person who will only do his homework until just before summer vacation starts.[97][98]
  • Kuzuha is the self-proclaimed brain of NIJISANJI Gamers and even says that he has the academic capabilities of one who graduated nursery school.
  • Kuzuha and Kanae have a longstanding friendship and call each other casually, but whenever Kanae feels like it, he'll give Kuzuha nicknames. He'll either call him Kuzuha or "omae" (you), "ku -chan", "kuzu-chan", "kuzu-kun", "kuzu-tan", "kuzu-pyon", "ku-tan", "o-kuzu", "sasha", "zuha", "zuha-san", "tanpopo-chan" (dandelion), and "cocoa-chan".
  • From 3 March 2020 until 2 April 2020, Kuzuha and Honma Himawari were available to be obtained as playable characters in the action RPG game Dawn of the Breakers.[99]
  • Although Kuzuha entered NIJISANJI through, and only after he was personally scouted, Kuzuha actually already first applied to NIJISANJI before even getting scouted.[100] Kuzuha has also mentioned once before, that while he was receiving scout invitations, among them were the NIJISANJI invitation and one apparently from a modeling agency (the company is speculated to be Twin Planet Entertainment). He rejected the offer from the agency because he said he was already set on joining NIJISANJI even before he was scouted.[101][102]
  • On 8 March 2021, Kuzuha updated his channel logo with a logo made by BALCOLONY who was also in charge in designing Kanae's 2nd Logo and ChroNoiR's 2nd logo. . The same BALCOLONY also designed the posters and logos for Your Name, A Silent Voice, Weathering with You, Fireworks, and more among many others.

Character and Lore

  • Kuzuha's "real" name is "アレクサンドル・ラグーザ" or Aleksandr Lagusa and was born in the demon world.[87]
    • He is also nicknamed "サーシャ" (Sasha) by his family.
  • Some years ago, the Lagusa Family migrated to the human realm because of the love for humans Kuzuha's father had. When they arrived, Kuzuha was quite clueless as to how the Human realm worked. And so, Kuzuha, with the Lagusa clan's power to change appearances from the blood they drink, turned into a young child to start as an elementary student and learn more about Humans.[87]
  • When Kuzuha first started streaming, he was very active and tried his best all the time in various fields because apparently, in the demon world, "being on top" was a common form of connecting with people, but now, due to various reasons, he has established himself as a weak character who is afraid of being flamed at every turn.
  • With his very materialistic personality, his plans for the future is to be proposed to and be fed by the oil king.[87]
    • In an interview, he mentions that he became a VTuber and wanted to become popular to find said oil king.
