She is not very bright and is extremely poor at studying. She frequently snaps at Futa's sharp tongue and shouts "You're fired!", but ultimately trusts him deeply. Her cooking skills are abysmal; anything she touches turns to dust. Her room is filled with self-made romance manga with nonsensical plots.

While he delivers precise and scathing insults to Sumire, he genuinely cares for her. In his private life, he is a hardcore idol otaku.

She looks exactly like her brother; at first, Sumire thought she was just Futa in drag. She is generally clumsy, such as being terrible at brewing tea, but she has high combat ability and a strong sense of responsibility. She has a relatively good relationship with Futa but gets along poorly with her younger brother, Fuga. However, she still rescues him when he gets involved in violent trouble. She has a strong complex about her small chest.

She is normally the personal maid serving Sumire's older sister, Suzune.

A young man who looks intelligent with his glasses. While his looks aren't bad, his personality is unimaginably bizarre. He is obsessed with Sumire, stalking her and writing dozens of love letters. He has a heart of steel, continuing his advances even after being harshly rejected by her. He also views the butler as a one-sided rival.

She is technically a genius but a bit unhinged, embodying the phrase "there is a fine line between genius and insanity." She develops strange inventions, like a handsome robot that hugs you from behind. Her sense of style for "special occasions" is quite unique. As the inventor of the group, she is often relied upon when difficult problems arise, but she is also a major troublemaker.
