Quick answer

Use the controller action assigned to Oni Eye in the current control layout, then verify the on-screen response before relying on the input. The exact button is platform- and layout-dependent and is not asserted here without direct confirmation.

What to do

  1. Check the active layout

    Open the controller settings and note the current mapping before changing anything.

  2. Trigger the action in a safe area

    Use the mapped input where the game can show a clear response without a boss or puzzle state obscuring it.

  3. Document platform differences

    Record the controller, layout and successful response separately for each platform tested.

Prerequisites and scope

The exact question has Similarweb demand and a small SERP containing official, manual and guide results. That is a strong page shape, but it still requires a current controller test.

Evidence notes

Official product and manual context are stronger than a video title for the input. The captured research did not provide a dedicated Oni Eye transcript.
