In Kaiji: Ultimate Survivor, he tormented the downtrodden and enticed them into playing games where their lives were wagered against incredible cash prizes. But even a cold blooded monster can't spend every moment of the day trampling others. And in the real world, death games require planning, funding, oversight, and execution. This is the story of a lone man who struggles between his employer, the president, and his own employees, the men in black...Tonegawa Yukio: Middle Manager!

The second meeting of the death game production team is held, and Tonegawa needs to make up for the bad first impression he gave his workers. But between the confusing names of his team members and their bizarre objective, can the executive make sure the conversation heads in a productive direction?

After a vicious act of betrayal in the last meeting, Tonegawa arranges weekend trip to an all-expenses paid villa to repair the cracks in his relationship with the team... but will it be enough?

With the proposal for Restricted Rock Paper Scissors finished, Tonegawa just needs to turn it in to President Hyoudou... The tyrannical, temperamental, explosively volatile President Hyoudou.

As the deadline for the design of the Restricted Rock Paper Scissors cards approaches, Ebitani feels insecure because of Saemon's repeated successes. Tonegawa tries to mentor the wayward employee, but will he listen?

As work begins to proceed on the first Restricted Rock Paper Scissors game, an unseen danger threatens to freeze the team's work to a standstill.

After being fired from Teiai and causing Tonegawa's salary to be cut, Ebitani returns hoping to make amends.

The annual round of hiring for Teiai has begun, with Tonegawa and Yamazaki interviewing potential new employees. Afterwards, Tonegawa goes out for lunch, but ends up getting a little more than he bargained for.

It's finally time for the first rehearsal game of Restricted Rock Paper Scissors. But will difficulties with equipment and participants spell trouble for Tonegawa's big project?

Tonegawa hits the road, with business to attend to outside of Tokyo, and hopes to find a chance for relaxation while away from home.

When President Hyoudou decides that he wants a body double, Tonegawa and the men in black begin a search to find the perfect doppelganger for their boss.

The day is finally here: Tonegawa and his team are going to host the first game of Restricted Rock Paper Scissors. It's all been leading up to this, but can they pull it off without a hitch?

We've seen that the Teiai Group runs a ruthless business. But what happens when people with debt stacked beyond the ceiling fail to show any signs of paying off their loans? Witness a trip into the secret hell on Earth inhabited by the most hapless of debtors... and how one man manages to make the most of his otherwise dire situation.

One of Ootsuki's regular excursions results in a clash of epic proportions, against an unexpected opponent...

Tonegawa is Teiai's number two man, but his position isn't exactly uncontested. When his rival, Kurosawa, steps into the picture even the battle hardened middle manager finds himself at a loss.

The time has come for personnel changes at Teiai. When everything is said and done, who will be left on Team Tonegawa?

Tonegawa's annual check-up leads to some lifestyle changes that are accompanied by unwanted attention, while Ootsuki finds something he never expected to encounter on one of his excursions.

With the recent transfers leaving him short-manned, Tonegawa welcomes three new employees to his team, and doesn't take long for two of them to start making waves within the company.

The man-eating Bog is a pachinko machine that makes a ludicrous amount of money for one of Teiai's underground casinos. The time has come for Tonegawa to collect the winnings, which means a showdown between him, the diabolical device, and the man who responsible for it: Ichijou!

Overseeing the Teiai corporate Twitter exposes Tonegawa to an account that seems to exist solely to hate on his company, triggering the middle manager's combative instincts. Meanwhile, Ootsuki's underground gambling games hit a snag when a rival foreman begins running his own entertainment scheme.

Two stories come to a conclusion, as Ootsuki concocts a scheme to usurp Odagiri's movie business, and Tonegawa tracks down the social media troll that has been flaming Teiai.

Tonegawa attends a class reunion where he hopes to see what's become of the classmates he always held in contempt. Meanwhile, Ootsuki's latest excursion is threatened when he gets unexpectedly sick.

Hyoudou's latest craving for diabolical entertainment is so twisted, people are afraid to talk about it... even the narrator! And then, wedding bells begin to ring for one member of Team Tonegawa.
