Real name's Carina, an alien who took human form to mess around on Earth.
The golden tufts on each side of her head are actually sensory receptors.
Loud and hyperactive, she's painfully direct.
She never thinks before acting, just does whatever pops into her head.
Plays the "I'm just a kid" card whenever she says something outrageous, then frantically backtracks a minute later.
Impossible to hurt and never catches colds, because that's how idiots work.
Picked the name "Kaizan II" simply because it sounded cool and vaguely related to her real name. The decision was made on a whim—no deeper meaning exists, because that's how idiots work.

真名是Carina，
化身成人形來地球玩的外星種族。
兩邊的金色毛髮實際上是感應器管。
精力旺盛又很吵鬧，坦率的直球型選手。​
​做事從來依靠直覺永不三思，想到什麽就會立馬行動。
總是以年齡小為藉口進行衝擊性暴言，發言一分鐘后又光速反悔。
非常抗揍，還永遠不會感冒，畢竟是笨蛋。
「海山二」這個稱號只是單純覺得很帥又和自己名字有關聯，
一拍腦袋決定的​，并無深意，​畢竟是笨蛋。
