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 curtain finally raises on this hustler’s waltz as it dances precariously along the boundary between crime and lawfulness—the Criminal Border.

Rin Akinashi (CV: 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 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.

Itsuki Ninomae

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.
