Following a deadly collision with a truck, Takafumi Takaoka"s uncle Yousuke "Ojisan" Shibazaki lies in a coma for seventeen years. When he awakens, Ojisan speaks a language and says he was taken to a realm called Gran Bahamal. Takafumi dismisses the tale as absurd until an enchantment lifts a glass of water into midair. Suddenly, they launch a YouTube channel to showcase Ojisan"s magic.
Now it is Takafumi"s duty to bring Ojisan up to speed on everything that happened while he was gone, from mastering the internet and gadgets to learning the result of the 1990s console battle—a loss that hit a SEGA fan hard. Using Ojisan"s insight, they grow their channel and confront comments and trolls together. Their videos attract viewers, and the duo must learn to navigate trends while preserving Ojisan"s mystique. As they grow, rival creators attempt to steal secrets, forcing the pair to protect their brand. This uncle‑nephew adventure promises to be anything but ordinary.
