Okitsu is taken by the police, and the SAGAS shareholders meeting turns into chaos. Now that Okitsu is no longer present, Miyazawa Family Office wins over powerful letters of attorney that leave the team with no chance of winning. Finding themselves in a bind, Nayuta takes the stage. Nayuta has fought alongside his colleagues to overcome many struggles in various situations. A great battle for the future of the game industry finally reaches the final stage. Which side will come out on top?

Nayuta decides to develop a game with his long-time enemy, Okitsu, to get back Atom’s technology. He falls into a slump, and Okitsu goes to meet a man who may be his last hope.

Several years ago has passed since Atom Toys changed its name to Atom’s Last Shot and made a fresh start. The number of employees has increased, and the company has regained its former energy. Nayuta and Hayato meet people at a gathering for game creators and begin to look toward the next stage of their careers. Umi has mixed feelings about this. Meanwhile, Okitsu senses an impending crisis when a large conglomerate, the Miyazawa Family Office, begins to acquire a large amount of SAGAS stock.

A year has passed since SAGAS acquired Atom Toys. What is going on in Nayuta and the other former employees’ minds? Their thoughts now inspire them to take action!

Nayuta and his friends are at a loss when their completed game is rejected by distribution sites. They receive a proposal from Okitsu at SAGAS, but Nayuta and his friends refuse to rely on his help.

Atom’s game was on the verge of being completed, but their data has been wiped clean. Nayuta and Hayato attempt to restore the game posthaste, but they argue over how to proceed. Umi is frustrated with her inability to bring it all under control. Meanwhile, Okitsu is planning his next move.

Ten months have passed since Nayuta and Hayato began creating games at Atom Toys. The characters designed by Shigeo and his team are full of life as they move on the computer screen. However, Kenyu Oyamada from Yayoi Bank suddenly demands immediate repayment of their loan. With the deadline in one month, all of the employees begin raising money. Then, publisher Aki Sagara suggests participating in a large-scale presentation competition that connects investors with game creators.

The new Atom Toys is finally on the move. Nayuta looks for a new partner, and Umi takes him to a game event where he bumps into Hayato Sugou.
