Sebastian made his way to Mephisto's office. "Done already?" Mephisto asked, once Sebastian entered.

Sebastian smiled, "if I couldn't do this much, what kind of butler would I be?"
Mephisto burst out laughing, "Of course!"

"About my other Master..." Sebastian began.
"Oh, Yes! About your other Master in England, How about I use my powers as king of time to handle your former master?" Mephisto suggested.

"What do You mean?" Sebastian questioned.

"Well...as king of time, I can pause time whenever I want. I was merely thinking that I could pause time around the England area. It would buy you time to quickly turn Rin into a Demon king. Of course, anyone surrounding England won't be affected unless they traveled there." Mephisto explained.
"So, what do you think about that plan?"

Sebastian pondered for a moment. " I think it's a wonderful plan. What will be the price of such arrangements? Surely you aren't going to do this for me without a deal."

Mephisto smiled, "You know me too well. I'll do this for you on one condition. You give me the soul of your next master."

Sebastian's eyes widened, "You want the soul of my next master?"
Mephisto nodded.
"I see. Very well, I agree to your terms," Sebastian said.

"It's settled then!" Mephisto declared. "Although, I can't believe you let Demonica escape. How unlike you," He added.

Sebastian sighed, "Yes, I agree. I killed all the other demons who were present however I couldn't kill her."

Mephisto chuckled, "could it be that you..."

Sebastian glared at Mephisto. "I assure you, that is not the case.
She wasn't working alone. A Demon king put her up to the task. One of the Demon king's want Rin Dead. I simply want her to lead me to that Demon king."

"In any case, you should really be taking care of Rin right now," Mephisto commented, changing the topic. Sebastian smiled, "of course. I will have to chat with you again some other time."

Sebastian left Mephisto's office and headed back to Rin's dorm room.
