Fubuki made their debut appearance in an unknown Discord server on April 1, 2021. Her account was originally created on July 10, 2020 as one of Keel's alt accounts, but it was eventually used to roleplay as Shirakami Fubuki. It is unknown whether Keel is the roleplayer behind this character, or someone else was involved. Throughout their tenure they changed very little.

Fubuki was a very sporadic character who made references to her source material often but was not necessarily a good incarnation of the real counterpart she was based on. She was posthumously regarded for her lisp and reactions which were both considered very humorous by Discord users like SEXHAVVER41. She was also known to be racist towards black people, making her controversial among many.

She made frequent references to an “old owner”, seemingly the owner of the account before she took control over it. This owner made various sexual advances towards many different people when they had control over the account which made Fubuki very furious when screenshots were taken of them containing messages of these things later on out of context. It is unknown whether Fubuki deleted these messages to prevent further damage, but she has known to be very horny herself and also make sexual advances, which gives rise to the theory that the “old owner” and Fubuki are the same person, and they forgot to delete the horny messages.

Shirakami Fubuki was impersonated by SEXHAVVER41 on one of his alt accounts on April 21, 2021. This account was known as Shirakami Fubuki#5744, different from the real account Shirakami Fubuki#5480. This impersonator made Fubuki furious and they frequently argued with the impersonator over who was real especially when the impersonator would be more racist and toxic than usual (although notably less horny).

Shirakami reportedly lost access to their account in 2022 and requested assistance through unknown means from the fellow Hololive LARP Inugami Korone, who pleaded to the original account owner for access to it back, but the plead was unsuccessful as Keel forgot or did not want to share access to the email attached to the account. This effectively killed the character off, as the roleplayer behind the character did not create a successor account to continue roleplaying.

It's assumed that Shirakami's direct successor is Kurokami Fubuki, a roleplayer who frequently plays on the cunny.zone Minecraft server, and has an account on cunny.zone. This character has made reference to not being good at English at some point and knowing Filled With Nothing, which confirms many peoples' suspicions, but there has been no direct confirmation found as of March 2026.
