For 17 years, Ojisan (Uncle) lived in another world, a mysterious fantasy land filled with magic, monsters, and adventure. But now, at 34 years old, he has finally returned to modern-day Japan. His nephew, Takafumi, is shocked to see him again after so many years, but what’s even more surprising is the strange things Ojisan has brought back from his time in another world.
Unlike most people who get transported to a fantasy world, Ojisan was not a brave hero or a chosen one. Instead, he was just a diehard Sega fan, someone who loved old video games more than anything else. But in this new world, his passion for Sega shaped his entire journey. He survived dangerous encounters, fought powerful creatures, and even learned magic—all while keeping his love for Sega alive. Now, back in Japan, he struggles to adjust to how much things have changed.
Takafumi quickly realizes that his uncle is not an ordinary man anymore. He still has his magical abilities from the other world, which he casually uses in everyday life. Whether it’s cleaning up a mess, fixing a broken object, or even showing memories from his past, Ojisan’s powers make life both easier and more bizarre.
However, he is also completely out of touch with modern society. Since he spent 17 years away, he missed all the advancements in technology, culture, and—most painfully—the downfall of Sega as a console maker.

My Uncle in Another World Plot
Ojisan’s stories from the other world are both hilarious and tragic. He talks about the hardships he faced, including being mistaken for an orc because of his rough appearance. Despite his incredible strength and magical abilities, people often rejected him, leaving him to fend for himself. However, his love for Sega never faded, and he constantly compares his adventures to classic Sega games.
As Takafumi listens to his uncle’s tales, he decides to document them, sharing the unbelievable experiences with others. The contrast between Ojisan’s fantasy world experiences and his attempts to adjust to modern life creates endless comedy. Watching him try to understand YouTube, smartphones, and modern gaming trends is both funny and endearing.
Beyond the humor, Ojisan’s Return: A Sega Fan’s 17-Year Isekai Adventure explores themes of nostalgia, adaptation, and the bonds between family members. Ojisan may be lost in the present, but with Takafumi’s help, he begins to find a new purpose in life. Whether it’s using his magic for daily tasks or reminiscing about his Sega-filled past, Ojisan’s return is anything but ordinary.
