Itsuki’s long-time acquaintance and fellow classmate.
The heroine of the final act.

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. Until now she has operated from the shadows, but now she takes her place in the spotlight as Itsuki’s partner.

An executive in the foreign Mafia syndicate that employs Meryl.

Despite her easygoing demeanor, there is always a dangerous gleam in her eyes. She has a weakness for food, and delights in sampling the diverse culinary offerings of Japan.

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. Currently the outward face of Itsuki’s business, she also acts as a deterrent and negotiator in dealings with other oragizations. In the end, she casts herself into the maelstrom alongside Itsuki and the others as she seeks to take control of the Umon-kai and impose her own vision of justice and righteousness.

Often found accompanying Kotoko, this girl is a member of an overseas Mafia syndicate.

Originally tasked with watching Itsuki and the gang, she found her goals aligned with theirs and now works with them to achieve her objectives. Her slight build and aloof demeanor give her an air of fragility, but in times of crisis, she reveals skills that are anything but ordinary.

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. This time, Tatsuya has resolved to stand by Itsuki no matter what, as they push forward to bring the Umon-kai to its end.

Beneath a geeky exterior lies his true identity as the leader of NEST—an emerging gang in the criminal underworld—and the protagonist of this series.

By chance, he creates a digital drug video which leads him into business with his childhood friend, Rin.

With the help of Hina, Kotoko, Meryl and all his allies, he overcomes the trials of the criminal underworld and steels himself to settle the score with his arch-enemy, the Umon-kai.
