Rina Saijō

Rina Saijō is known for her very large bust—G cup, measuring 92 cm, surpassing other main female characters.

She has a high-class, well-cared-for look, and is always seen escorted by bodyguards.

Her eyes often change to star or heart shapes depending on her mood.

Rina is sweet but extremely naive.

She has trouble talking to boys and reacts awkwardly or confusingly, sometimes making inappropriate comments without realizing it.

She is very comfortable with girls, often being physically affectionate in a way that other students call "yuri" (girl-girl romantic/friendly).

Rina likes to make others happy, and often cheers up friends who are upset.

Rina grew up always attending girls’ schools.

She transferred from a super-elite girls’ high school to a co-ed school, where Haruka and Akiho are students.

Her family is very wealthy, and she is used to being protected.

Rina’s father worried about her intense friendships with girls, so he made her transfer to a school with boys.

Her mother worried about her making friends with boys and so did not allow her to have a cell phone at first.

Her home is guarded by a special system that only reacts to men.

If a man is detected, bodyguards immediately appear.

For this reason, when Haruka visited Rina’s house, he had to dress up as a girl.

Rina can communicate with her pet dogs, Butter and Margarine.

These dogs share some of Rina’s odd habits and personalities.

Rina’s eyes can change shape—stars when she gets an idea, hearts when she thinks something naughty, and sometimes flowers when she gets really happy.

She is a close classmate to Haruka Shinozaki and Akiho Kosaka.

She often gets involved with Akiho Kosaka and Shizuku Ariyama in a jokingly romantic or "yuri" way, much to their embarrassment.

Her intense closeness with girls led to her having many fans in her previous school.

At her new school, Akiho and Shizuku sometimes become "victims" of her overly friendly behavior.

Her father is very protective of her relationships with women.

Her mother is very protective of her relationships with men.

Rina is always escorted by multiple bodyguards, who are big, strong, and look alike.

She loves to play with her dogs Butter and Margarine, and she can talk to them.

Rina shows kindness and comforts friends, especially if she thinks someone has had their partner "taken."

Rina’s car rides to and from school are always in a black car.

She is always surrounded by tough bodyguards at all times, especially even during class.

Her dogs’ unique habits are said to be just like their owner’s.

Her eyes are like mood indicators—changing shape with her feelings.

Trouble with Boys and Girls

Rina arrives at the co-ed school not knowing how to talk to boys at all.

Her attempts to interact with them lead to confusion or chaos, especially since she is not shy about adult topics.

The Girl-Fan Club

Rina’s affectionate attitude with girls draws a huge following, and many girls in her old school were big fans thanks to her yuri style.

After transferring, girls like Akiho and Shizuku often find themselves the focus of Rina’s attention, sometimes unwillingly.

Super Security at Home

Rina’s parents set up strange rules due to worrying about her relationships.

Her house has high-tech systems that react only to men; bodyguards act fast if a man is found.

That is why Haruka had to pretend to be a girl when visiting.

Fun with Dogs

Rina can talk to her two dogs, Butter and Margarine.

She loves playing with them, and the dogs have similar personalities to Rina.

Rina’s eyes are a unique feature, changing into stars, hearts, or flowers depending on what she is feeling or thinking about.
