The blog post for today will be about the Vocaloid Shion brothers. There are countless different Shion brothers. They are all derived from the official Vocaloid Kaito. There is no official last name for Kaito, so the popular last name Shion is used as a last name for all of the Kaito derivatives. Some of the most popular Shion brothers (excluding Kaito) are Akaito, Nigaito, Kikaito, and Zeito, to name a few. There are also some that are not well-known, such as Seito, Hairaito, or Xaito. There are a lot of other Shion brothers as well, with some being more popular than others, and more being created all the time.
