PSIjian! Parting with the Grandparents is the ninety-forth chapter of Volume 9 of The Disastrous Life of Saiki K (Saiki Kusuo no Sai-nan) published in the 4th of July 2014.
Kusuo and his parents are heading home but Kumagoro doesn't want them to leave. While driving to the train station Kusuo foils Kumagoro's plans to have siphoned the gas from his car. Kurumi acts suspiciously, claiming no psychic powers were involved knowing the gas siphon was in the trunk but Kumi and Kumagoro let it slide until they come across a rock slide blocking the road. It is then that Kusuo decides that he has had enough and reveals his powers to his grandparents to clear the rock slide.
