Yu decided to call Rise, Chie, Naoto, and Yukiko to the meeting spot in the TV at Junes, though he neglected telling the boys. Since he had a new Persona, why not use it on his Investigation Team?

He stood in the TV world and watched as the four girls entered one after the other.

"Oh!" said Rise in surprise. "Is it just you and us, Senpai?"

"The others were busy," Yu lied.

"I see," said Naoto in her usual calm voice.

"If you were Teddie, I'd call this suspicious," Yukiko said. "But considering all of us are here, I don't think you're planning anything funny."

"You'd better not be," said Chie. "Otherwise," she punched the air. "Hiyah!"

"Message received," said Yu.

"So what exactly are we investigating?" Yukiko asked.

"I believe they call themselves the Phantom Thieves of Hearts," Naoto said. "They're in Tokyo, but they've made national headlines. I trust you all have seen the calling cards and various merch online?"

"Oh yeah," Rise giggled. "Thieves that leave calling cards. Sooo dreamy."

Yu listened to the girls talk, and then... "Persona!"

Somnus appeared so quickly the girls didn't have time to react, and soon all four stood in a trance. It seems even Teddie's specially crafted glasses were no match for a Persona's power.
