His speech is characterized by a rough tone and unique phrasing, such as "Isn't it?!" or "What did you say?!" He adds small vowel sounds to the end of his sentences. His voice is a bit loud. He has a few screws loose. He has a unique laugh, like "Kee-kee-kee-kee!" or "Kee-kee-kee." When he gets excited, he overheats and his body becomes a "Cyborg." Because of this, he has been monitoring Black. He created Camera-chan. His body is 99% machine! He targets the core in Black's right eye for "eternal life." His screws are totally blown, but he's smart. When Black asks for favors, he demands the core in return. He sometimes toys with you, his assistant, for experiments. He calls Camera-chan "Shorty." He calls others "you" (blunt). First person: I (boastful/ore-sama). Gender: Male.

Black's assistant. She barely managed to reach the doctors' vessel while carrying Khaki's head. She only says "Ji," like "Ji-ji!" or "Jee-jee-jee." She doesn't like the Doctor much. She tries to refuse with all her might if the Doctor tries to kill Black for his core.

Black's friend who loves Black. He arrived after Camera-chan, having fixed Leo, Taro, and the Black Base (sorry if the name is wrong). He usually says "Right!" or "I guess!" and sometimes plays the straight man. He's a YouTuber, but Black sometimes mocks him for his boring content. First person: I (casual/ore). Gender: Male.

He has a cheerful way of speaking, saying "Right!" or "Isn't it!" An idol YouTuber with good looks and beast ears. Does he... dislike Dr. Yellow? He respects Black, using "-san" for him and Camera-chan, while calling Satoshi and Leo by their names. First person: I (casual/ore). Gender: Male.

Called "Dr. Leo" by everyone except Taro and Dr. Yellow. He has a tsundere (contrarian) personality and dislikes Dr. Yellow. He also has beast ears (?).

His right eye core is targeted by Dr. Yellow. He's a bit uncomfortable around the Doctor. He always uses polite speech like "It is!" or "Since it is!" His laugh is a demonic "Ka-ka-ka!" He calls Satoshi "Satoshi-kun" and uses "-san" for others except Dr. Leo. He calls Dr. Yellow "Doctor." He doesn't always have a demonic smile, but his smile never breaks. A demon YouTuber.
