INTRO
Itsuki has his NEST. But what did he gain—and what did he lose—to claim it?
With a powerful enemy in Shinonome gone, Itsuki and the gang's business is thriving.
After countless twists and turns, Rave is now a massive success, generating an immense amount of profit and making "NEST" and its operators infamous in the underworld.
However, with that success comes a creeping unease and the frustration and pure rage of losing something irreplaceable.
Right now, neither Itsuki nor his best friend, Tatsuya Yorozuya, cares for the money and status flowing their way.
All they can see is their goal: to take the life of Umon-kai leader Goro Teshigawara.
For that, Itsuki would not hesitate to throw away his life.
Watching his dangerous resolve with growing concern is Rin Akinashi, his business partner and childhood friend.
And looming ever closer is the shadow of Mafia syndicate executive Luca.
Life? Or death? Light? Or shadow? Revenge? Or...?
The final curtain rises on this hustler's waltz. One last dance, precariously, along the boundary between evil and justice...
CHARACTERS
Rin Akinashi
Voice: Cyclamen Kaori
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 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.
Hina Yorozuya
Voice: Suzu Sazanami
―
Kotoko Teshigawara
Voice: Ion Momoyama
A student in the grade above Itsuki 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.
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.
Meryl Hathaway
Voice: Nene Arisu
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.
Tatsuya Yorozuya
Voice: Ii Kinniku
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.
Luca
Voice: Sara Ayumi
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.
Shoji
Voice: Sho Sakuma
A teacher at Badman Academy, Shoji is a regular customer of Rin and Hina's escort business.
With strong connections to other regular customers, he actively cooperates with Itsuki and Hina.
Despite his "unusual" preferences, he is a good person at heart.
Shoji is seemingly well-known among wealthy circles and is accordingly well-connected.
Goro Teshigawara
Voice: Gunso Hatoman
The leader of the "Umon-kai" Yakuza syndicate and Kotoko's father.
Itsuki Ninomae
Voice: ー
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 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.
