"The Unlikely Uncle: A Heartwarming Start to 'Hey, Soshite Watashi wa Ojisan ni'"
The episode ends with Airi (as Kenzaki) visiting her original apartment. She knocks on the door. It opens to reveal her own body—now inhabited by Kenzaki’s consciousness. The 52-year-old man in a 24-year-old woman’s body smirks and says, "Hei. Omae, nani shiteru no?" (Hey. What the hell are you doing?)
The first episode follows the "body swap" trope—familiar to fans of Your Name or Freaky Friday —but with a horrific twist. Aoi (in the old man’s body) must navigate the real world, while Ojisan (in Aoi’s young female body) begins to act in ways that are deeply unsettling.
