Four more figures showed up and Shiranui recognised two of them as his mother, Mizumi Tsukiko and his father, Kaika Tsukiko.  The other two were two of his father's Pokémon: a Charizard, Hokage and a Greninja he had battled named Mizukage.  "Hi son," Mr. Tsukiko greeted.
"Mum, Dad, Hokage, Mizukage!" Shiranui exclaimed in shock as well as glee, "I wasn't expecting you lot to show up here."
"Scott informed us that you were about to beat the Battle Frontier," replied Mrs. Tsukiko, "So we decided to come here to the Battle Pyramid to cheer you on."
"Thanks," said Shiranui.
