Uncle from Another WorldFanfic, x Reader & AI Roleplay

Uncle from Another World follows a man known as "Uncle," who has returned from another world, as the series' protagonist. Many chapters are structured so that roughly one month passes in the real-world timeline per episode, and some episodes reflect real events, such as changes to YouTube's terms of service in February 2018. The real-world segments of the story are set in Fukuoka City, Kasuga, and Onojo in Fukuoka Prefecture.

The series is known for its comedic approach, which turns common tropes and conventions of the "isekai" (another world) genre on their head. Because the story is told from the perspective of someone who has already experienced another world and returned to reality, it approaches familiar isekai elements from an unusual angle compared to typical works in the genre. The way real-world events are woven into the narrative's timeline also gives the series a distinctive sense of continuity.
