The effect only mentions Square in general, so it will affect all Squares including the Player Square.

Please note that unless it is stated (either by the text or by diagram), Square refer to all Squares on the field including Player Square. If a card's ability only affect cards in Normal Square or Player Square, it will be mentioned in the text as is.
