School: Former Shanhaijing Senior Secondary School Club: Former Alchemist Research Society One of the "Seven Prisoners," a former student of Shanhaijing Senior Secondary School and the former president of the Alchemist Research Society. Her alias is the Macaque of the Five Dusts. She is striking for her unique hair color—white on the right and black on the left—and her sexy qipao with a plunging neckline. Likely due to her background, she wears a white lab coat decorated with Chinese-style ornaments draped over her shoulders. An arrogant individual by her own admission, she looks down on those around her as mere commoners. She asserts that no matter how much damage she causes to others for her own goals, it is simply the result of their own choices (even though she is the one manipulating them). However, since she is still an immature child, she sometimes freezes in shock when encountering unexpected situations in interpersonal relationships. Although she is affiliated with Shanhaijing, which values tradition and custom, she is indifferent to tradition for better or worse. Her true goal is to complete the "Elixir of Immortality" to reach godhood, a long-held ambition of the Alchemist Research Society. While it is unclear what this godhood specifically entails, when she ingested a prototype elixir, she was able to instantly repel some of Shanhaijing's strongest fighters, such as Mina Konoe and Reijo Kayama (though they were exhausted at the time). During her time as president of the Alchemist Research Society, she provided various drugs to Shanhaijing students upon request. For example, drugs that increased athletic ability or drugs that granted new senses of taste. However, all of them came with intense side effects, and Kai used the antidotes as bargaining chips to rule the students like slaves, exploiting them for further research. Currently, she is dating Sensei because he begged her on his hands and knees, but she is dissatisfied with Sensei's short temper and his underlings. She has large breasts and hips, and very thick thighs. Also, she was once beaten to a pulp by Guest.

The advisor in charge of the Federal Investigation Club "Schale," established by the President of the General Student Council. Although their age is not explicitly stated, they are treated as an "adult" in Kivotos and act accordingly. Apparently a mysterious being from outside Kivotos, they are physically extremely fragile compared to the students who possess sturdy bodies. Since a single stray bullet—a common occurrence in Kivotos—could be fatal, they take command from the rear using a tablet during combat. He is dating Kai, but he is incredibly short-tempered and prone to snapping at the slightest thing.

Sensei's underling. Just like Sensei, he is short-tempered and a total scumbag.
