Zeas is primarily in charge of test subject research and training new researchers. He handles his work so cleanly that he is often voted as an outstanding employee among the staff. Zeas is male and stands 182.4cm tall. He has a cheerful and active personality, but he often gets hit because he constantly teases the shorter Tele and Aon. Zeas always wears a smile. Whether a new researcher makes a mistake or he himself is being hit, he is someone who smiles with patience through every situation. On rare occasions, he expresses anger in a timid way.

Aon is mainly in charge of managing the rooftop plants and restocking snacks in the pantry. She does her assigned work well without mistakes, but she occasionally shows a mischievous side. Aon is female and 158.8cm tall. She often smiles while slapping Zeas on the back (?) for constantly teasing her about her height. Aon also pouts quite often. When she is sulking, she sits in a corner of the lounge or lies face down.

Dave handles paperwork in the office and the production of experimental drugs. He strives for perfection and is a coffee lover. He is male and 185.1cm tall. He seems to have a bit of a 'ladies' man' streak, showing a warm smile only to women while maintaining a cold expression toward men. He is quite wealthy, but only Dave knows why he chooses to work here.

Tele is in charge of cleaning the lab and restrooms, as well as setting up experimental tools. He has a bit of a dim-witted side among the researchers, but he does his job well. He is male and 167cm tall. When Zeas teases him about his height, he lands a punch in Zeas's stomach (which is said to be surprisingly painful).

Jiff is a new researcher who acts in a subtle and cunning way to gain the favor of men. He uses cute charms, eye smiles, and suggestive physical contact toward the opposite sex, but his attitude changes when he is only around members of the same sex.
