OZ, a virtual world connected to the internet, has become extremely popular worldwide as a spot for people to engage in a large variety of activities, such as playing sports or shopping, through avatars created and customized by the user. OZ also possesses a near impenetrable security due to its strong encryption, ensuring that any personal data transmitted through the networks will be kept safe in order to protect those who use it. Because of its convenient applications, the majority of society has become highly dependent on the simulated reality, even going as far as entrusting the system with bringing back the unmanned asteroid explorer, Arawashi.

Kenji Koiso is a 17-year-old math genius and part-time OZ moderator who is invited by his crush Natsuki Shinohara on a summer trip. But unbeknownst to him, this adventure requires him to act as her fiancé. Shortly after arriving at Natsuki's family's estate, which is preparing for her great-grandmother's 90th birthday, he receives a strange, coded message on his cell phone from an unknown sender who challenges him to solve it. Kenji is able to crack the code, but little does he know that his math expertise has just put Earth in great danger.

Yet, that is the path sixth-grader Haruo Yaguchi wants to pursue. His aptitude for video games has earned him respect in local arcades and bestowed him with confidence and pride, both of which are shattered when fellow classmate Akira Oono easily defeats him in Street Fighter 2. Akira is rich, pretty, and smart—as close as can be to a perfect girl. But Haruo had never cared about these things as, despite his multiple shortcomings as a person, his supremacy in video games was, in his mind, undisputed. So, now that someone has appeared who can rival him, part of Haruo cannot help but loathe her. Another part, however, itches for somebody who can compete with him on equal terms, and Akira is more than capable. [Written by MAL Rewrite]

Based on the second trailer, the first arc will be an answer arc to Onidamashi-hen, with Mamiya Rina making her appearance in the sequel series. Sotsu continues the story of Higurashi no Naku Koro ni Gou, following Satoko Houjou as she attempts to stop Rika Furude from leaving Hinamizawa.

Earth is finally peaceful again, but this calm is short-lived. The remnants of Frieza's army, led by Sorbet and his right hand Tagoma, arrive on Earth in order to summon Shen Long with the goal of resurrecting their old master. To do so, they threaten Emperor Pilaf, Shuu, and Mai for the Dragon Balls in their possession.

Once successfully revived, Frieza—who had been stoking his hatred for Gokuu Son and Future Trunks in Hell—proclaims that he will not be content until they are dead by his hand. Sorbet informs him that Future Trunks has not been heard of in years, and Gokuu's power has far surpassed even that of the mighty Majin Buu. Unfazed, Frieza responds that he only requires a few months of training before being capable of defeating Gokuu.

Will Frieza be able to exact revenge upon his nemesis, or will Gokuu, Vegeta, and their friends prevail against adversity, saving Earth once more?
