Sakura's mother has the appearance of a grade schooler, which is why she was mistook as Sakura's younger sister. She likes to cosplay, always dressing up in different attires and having a closet full of different outfits. Despite her appearance, she is shown to have a violent side after consuming alcohol. Rei describes her as "being blind in love for her children" because she has taken pictures of every memorial moment of her daughter (from her first day of school to the first time she ate wasabi). Ironically, she whines that she should have taken more.

Ikumi Suzuki is one of the members of the Second Newspaper Club, and herself comes from the Sports Club. She is childish, energetic and cute but she isn't too smart and has a short attention span; the advice she gives for the Newspaper Club's advice column is usually poorly thought out and ill-advised, though it often compliments the other members' contributions. Ikumi seems to be somewhat perverted, or at least naive, as she frequently tickles or otherwise touches other characters inappropriately, even going so far as to grope Fumi Kujou's breasts on multiple occasions. Ikumi loves eating and often spends club meetings stuffing her face with sweets and stick snacks, stick snacks being her favourite food. She also shows great admiration for the fictional superhero Koganen and states that the reason that she chose to specialise in athletics was because when she was a child she hoped to one day fight alongside Koganen. Even though Koganen's stage show was long since disbanded, Ikumi still occasionally meets with the actor who played the character, despite his reluctance to do so.
