Summoning a celebrity

Michael Benson got a ping on his phone. He looked at the message and smiled. "What is it daddy?" Dinah asked her father.
"I just got a notification that a big celebrity has signed up for the game." Michael told her.
"That is one more Djinncumon in your harem." Dinah's statement punctuated with a naive giggle and an innocent smile which added an extra layer of irony to her statement.
"Right you are sweetie." Michael said before he got up from the table. "If you will excuse me, but I smell a marketing opportunity. Let me contact them and see how they feel about becoming the face of Djinncumon."

"That sounds like a great idea." Dinah said.

"Who is it?" Michael's wife asked. "Which celebrity is going to become the face of your game?"
