In January of 2020, Kito and his longtime collaborator Koruta announced that they were merging their accounts. As of April 2020, while Kito still possesses Pixiv, Twitter, Nicovideo and Pawoo accounts in their own name, most posts are made on the joint Pixiv and Twitter accounts: see the new Kito Koruta joint artist tag. The last upload on his Pixiv page is a formal statement of the account transfer.
