Aki Nijou

Aki Nijou is tall, about 170cm.

She has a very curvy and glamorous body, with a large bust that stands out in the whole series.

Her chest moves a lot when she moves, which is often shown in the series.

She also has wide hips and a fit, adult look.

Boys at school think she has the best figure.

As a student, she wore twin tails and dressed in outfits given by Minori Rokujo, which often had her wear skimpy swimsuits and bold costumes.

Now as an adult, she still likes to wear sexy clothes and has lost her embarrassment about them.

Aki Nijou is very kind and can't say no when someone asks for help.

She may be a bit shy and embarrassed, but she will often do almost anything if you ask.

She helps students often, even letting two boys put oil on her skin at summer camp.

She has a soft spot for challenges and can be surprisingly playful, doing things like cosplaying in response to silly requests.

Even though she seems like a perfect mature woman, she feels a bit insecure because she has never dated anyone before.

She gets embarrassed if anyone mentions that.

Aki Nijou is a graduate of Tenbi Academy and was one of the first members of the Maken-Ki club.

While at school, she was also a part of the student discipline committee.

Ironically, she was said to be the one who broke the most rules herself, wearing bold costumes thanks to Minori Rokujo's influence.

After graduating, she returned to Tenbi as the school nurse, art teacher, and Maken-Ki club advisor.

She lives alone and has learned to be good at cooking.

Aki has the power to use "Element," which lets her heal people even without using a Maken (special weapon).

She owns a Maken called "Valhelm," which she wears over one eye, though she usually keeps it as a pendant.

This Maken can diagnose injuries or illnesses by making bad spots look dark.

It cannot recover fatigue, but it's very helpful for medical checks.

She is very good at medicine and health care, so students trust her.

Aki Nijou is respected and liked by many students, especially boys, because of her looks and kindness.

Takeru Ooyama calls her a "perfect superhuman."

She has a secret crush on Akaya Kodai.

Her mother is always trying to set her up for arranged marriage meetings, which Aki hates.

To avoid them, she once lied that she already had a boyfriend and sent her mom a picture of herself with Takeru Ooyama.

The Arranged Marriage and Forced Trip

Aki's mother keeps trying to arrange marriage meetings for her.

To escape this, Aki lies and says she is dating someone.

Her mother asks for proof, so Aki takes a photo with Takeru Ooyama and sends it.

Her mother believes it and has someone use Element handcuffs to link Aki and Takeru together.

They are sent on a forced trip to Okinoshima island.

The Two Days on Okinoshima

While on the island, Aki and Takeru have to spend two days together, always attached by the handcuffs.

They shower together, bathe together, and even sleep in the same bed.

At one point, a storm makes the mood romantic, but friends like Haruko Amaya interrupt before anything big happens.

Through these two days, Aki comes to see Takeru's kindness and feels the excitement of being close to someone.

She starts to see him not just as a student, but as a man.

Aki Nijou has many scenes in the series that are just for fun or fan service.

In the manga extra comics, Kengo Usui often imagines her doing funny things, like being part of a silly "king's game" or teaching boys about how to make babies.

She is very good at cooking, thanks to living alone for a long time.

Fans from inside and outside the story often call her "the best girl in the series."
