The mysterious girl accompanying Kotoko, and the heroine of Part III.

Tasked with a surveillance mission, she transfers into the school Itsuki and the others attend. While her slight build and expressionlessness leave a faint impression, she exhibits formidable skills in emergencies. Meryl takes her orders from an organization separate to the Umon-kai and acts on their behalf.

She likes sweet food.

Itsuki’s long-time acquaintance and fellow classmate.

A paragon of perfection with good looks, exemplary behavior, and excellent grades, she is popular with boys and girls alike at school. However, this is merely a mask, hiding the cunning, scheming vixen she really is.

Despite a wealthy upbringing, she has an extreme attachment to money, earning a fortune working with Hina to operate a large-scale escort business of her own. She maintains a behind-the-scenes role in the business and does not change that stance, even when the gang acquires their club. Rin is meticulous in covering her own tracks, and she never contacts anyone other than Itsuki and Hina. She always takes care to ensure she has an escape route ready to go at any time.

Hina has her share of unsavory friends, but she herself is friendly and likable.

She places her full trust in Itsuki, and the two of them have overcome dangerous situations together. While she and Itsuki are not lovers, they do share a physical connection.

Currently a party to Rin’s escort business, she also aids Itsuki and the gang in their venture. With her sharp observational abilities and excellent communication skills, Hina is entrusted with the in-person running of the club.

A student in the grade above our protagonist at the same school.

Though her father is the boss of a crime syndicate, Kotoko still has a sense of what is just and right. Although shaken upon learning that the Umon-kai is not on the side of justice, Kotoko joins forces with Itsuki as she follows what she believes to be the right path.

While her relationship with Itsuki is physical, like Hina, she is not romantically involved with him.

Kotoko tends to prioritize appearances and often wears a kimono. She takes the roles of figurehead, deterrent, and negotiator in Itsuki’s business.

Hina’s older brother.
A student at the delinquent-filled so-called “Badman Academy,” he is also the leader of DREAD.

Thanks to Itsuki negotiating on his behalf, the debt Tatsuya’s parents owed to the Umon-kai was written off, leaving him free to cooperate fully. He and his associates in DREAD help with the running of Itsuki and the gang’s club.

He sees Itsuki as his friend, and Itsuki trusts him in return.

The schoolgirl responsible for Itsuki and the gang being saddled with twenty million yen of debt.

The owner of a strong sense of self-preservation, Shiori blames any inconvenient truth on others. It seems she has been attending school as though nothing happened ever since the incident.

While she puts on a refined act at school, in reality, she is a sex-addicted slut. Apparently, she enjoys using the digital drug during sex so much, she is willing to do it for free if it means she can watch the video.
