I couldn’t verify a specific I.N appearance on King of Masked Singer from the available information. The show first aired in April 2015, but the results I found did not show an I.N episode match.

What I found

  • The current show history confirms King of Mask Singer began in April 2015.
  • Recent coverage I found was about other guests, not I.N.
  • I also found a 2025 report saying the show is moving to a seasonal format after its regular run.

Best next step

A more precise answer would need I.N’s stage name, episode title, or a clip reference, because “I.N” can be easy to miss in general search results.
