Kai Saikota

Kai is a tomboyish girl who taunts those who belittle her, regularly burps, and swears without holding back. This tough, tomboy persona is quite surface level, however, with her describing herself as a "softie" during her donothon, Kai tends to wear her heart on her sleeve and is quick to get emotional when her fanbase breaks from their normal, playful roasting to showing their genuine appreciation for her. Adding on to her gap moe, Kai makes an effort to remember returning chat members' names and read/respond to messages (albeit mostly through trying to make fun of the chat in a joking manner).

She is very fond of "zoomer" jokes. Thus, she doesn't hesitate referring to popular memes like "deez nuts", or spamming the Vine Boom on her sound board.

Kai quickly admitted to being a down-bad type, notably by simping for her genmate Momo Otako. She also tends to simp for any handsome man and is in conflictual romance with Juna Unagi.

A challenge at OffKai Expo revealed she is also the least smart member among her genmates, being unable to discern a single lie about them and Riro Ron. Momo said Kai also got 0 points on another quiz ENdless did together before debuting.

• Her fanbase are the Kamisitos. Kai gave them an official design on 10 July 2024 with Poko Rakun's help. They look like crimson dragons with black horns, yellow belly and no eyes.
• Fans that join her membership are the Saikos (Although Kai tends to refer to them as "Membies", instead).
• Since its first appearance, K.AI, her AI alter ego, gives the opposite vibe of Kai because she seems much more confident and efficiently roasts the chat without any sort of mercy or emotion. While Kai is a "bottom", K.AI incarnates the "top" personality.
• A running joke among her fanbase is that her hip scales look like cured ham, leading to them using the nickname "Ham Hips" in various forms. She then began playing into the joke more, including referring to herself as Detective Ham Hips on her Unsolved Case Files handcam stream. The joke originally began when Juna Unagi made the connection during a Mario Party stream.
• Kai's mascot is Nimbussy, a blue sky cloud with pink cheeks.

• "Kaiju," alongside Juna Unagi.

• Living her dragon life, Kai was called out by an old man on a rainy day. The old man begged her to make the rain stop in order to save his people and their food from flooding. Kai didn't care about being worshiped as a god, but she changed her mind when the man talked about offering food. Once she chased clouds in the sky and brought back the sun, the village praised her like a dragon god, gave her food and a shelter for living. In exchange, she kept helping people. However, she asked someday for nuggies and fries and got no positive response.
• She has a little cloud friend named Nimbussy, or Nimby for short (as decided by Momo Otako and chat).
• Like a Charmander, Kai would die if her flaming tail were to extinguish.
