When Sawatari came to him asking what is going on, Reiji knew he had to tell him. He told him of the upcoming dimensions war between him and the Professor from the Fusion Dimension, but he didn't tell him that the latter is actually his father. In the screen, a girl who looks like Yuzu named Serena, also from the Fusion Dimension, is with Kurosaki and Tsukikage dueling three members of the Obelisk Force, warriors from the Fusion Dimension. Reiji gives Sawatari the chance to help them.
"And that's what happened," Reiji finished. "You should go out there and help them with the situation, Sawatari."
"On it, Reiji Akaba!" Sawatari does a thumbs up with excitement before leaving the security area.
"Sir, you told him everything about the situation except for the intrusion penalty," a Leo Corporation employee said nearby. "Why didn't you?"
"Let's just say I'm going to have much fun with what happens to him next," Reiji smirked.
It's just as he expected when Sawatari entered the 3-on-3 duel on-screen and the latter not only loses 2000 life points but also gets electrocuted for trying to intrude this duel.
"This moment has been recorded, right?" Reiji asked.
"Yes sir, it is," his employee responded.
"Good. I wanted that to be memorable myself."
Reiji smirked on what he saw on the screen, showing that he had his fun of not telling Sawatari about the intrusion penalty.
Author's Note: That moment from Yugioh Arc-V episode 48 where Sawatari not only loses 2000 life points but also gets electrocuted for trying to intrude the duel is quite funny. It's more funny when he said that Reiji didn't tell him about this.
