EPISODE CONTEXT
As episode 1 of 13, this is the foundational setup for the entire series—introducing the core relationship between Takafumi and Ojisan, establishing that Ojisan's fantasy world experiences were real, and anchoring the show's unique reverse-isekai comedic angle. No prior context is needed; everything starts here. Subsequent episodes build on this premise by diving deeper into Ojisan's Granbahamal memories and the increasingly chaotic ways his abilities and outdated worldview collide with modern life.
