--------------------------------
Akaito (アカイト) is the younger 'twin' brother of Kaito. He uses an octave lower voice than Kaito, and has red clothing, as well as red hair. His item is a Habanero Pepper, and is depicted at least once to have interest with Neru, though some assert that he is in a romantic relationship with Muri Anone or even Mikuo Hatsune. Two variations of Akaito exists; a mere color-swap with Kaito, and another with his coat colored black.
Kikaito (キカイト) is another brother of Kaito, who uses two octaves lower than Kaito and wears yellow. Unlike the rest of his brothers and sisters, he has a very robot-like body. His item is a lemon cotton candy.
Taito (Japanese: 帯人 Taito Chinese: 白隴 夏)is another brother of Kaito's. He has a higher pitch than Kaito,thugh sometimes lower when in "yandere mode", and his color scheme is purple. His items are bandages and an eyepatch, while he wields an icepick as a weapon. He is a Yandereloid, and he has violent tendencies, especially when provoked. Often depicted as wounded and sometimes bloodied, but not exactly weak, and his injuries is assumed to be the result of his violence.
Akaiko (アカイコ) is the red-clothed version of Kaiko. She is equivalent to what Akaito is to Kaito.
Kikaiko (キカイコ) is the yellow-themed version of Kaiko. She is equivalent to what Kikaito is to Kaito.
Nigaito (ニガイト) is another addition to the Kaito family. The sleeves on his coat are longer than his arms. His color scheme is green, and he is known to be very shy. Nigato is also sick a lot, thus he will wear his scarf up over his face most of the time. He likes apples, as he would say "an apple a day keeps the doctors away".
MoKAITO (モカイト) is a brown-schemed version of Kaito. His name comes from 'mocha', which is pronounced 'moka' in Japanese. As evidenced by his name and color, he likes coffee, but also enjoys hot cocoa with milk and sugar. He likes it this way because the 'smoothness' helps to keep his skin smooth as well.
Mekaito (メカイト) is a giant Hachune-ish version of Kaito.
Kamaito (カマイト) is Kaito as a drag queen. His name comes from combining the word Okama (お釜 Okama Lit. Transvestite) with his name. He wears makeup, a purple feather-lined jacket (often mistook as a boa), and a long blue dress with slitted thighs.
Zeito (ゼート) is the negative version of Kaito. He represents everything dark and depressing in Kaito and is rarely seen smiling. He has a slightly higher voice than Kaito and hates it. Because of this, he doesn't sing very much. Zeito is sometimes depicted as a Tsundereloid or Gothloid and spends most of his time playing alone with his yo-yo or talking with Miku Zatsune on rare occasion. He is described as Kaito's "Zatsune" equivalent because while she represents everything sexual in Miku, Zeito represents everything negative in Kaito. The two are often seen coupled.
Miku Zatsune (雑音ミク Zatsune Miku) is Miku's 'dark side' with a red theme instead of teal. She is said to be a daring or sexy version of Miku, and is said to sing songs with sexual content.
Kiku Juon (呪音キク Juon Kiku) is a red-and-white Miku. Her name is possibly inspired from the film Ju-on She is Yandere, using two cleavers (commonly called dozuki) as a weapon. She is Taito's lover and part of the Yandereloids.
