Gets himself two maids.

"Alright," Natsu mused, writing in the Note, "When Lucy Heartfilia calls Natsu Dragneel Master, Virgo will immediately accept that her Mistress/Summoner is his servant or slave, and thus, consider herself a faithful servant of Natsu by extension. She will still obey Lucy, but will prioritize any orders Natsu gives. She will obey anything dutifully, and love getting any kind of praise from him."

He then turned back to Lucy, and said, "Alter Ego: Maid."

Lucy blinked and smiled. "Hello there Master Natsu! You'll find the house is in great condition! Shall I prepare a meal for you?"

"Oh? You're Natsu's servant Princess?" Virgo asked, blushing slightly. "I suppose that means I'm also yours Master, doesn't it," she bowed her head to Natsu dutifully.

Natsu grinned. "Yes, yes it does," he agreed.

"Please forgive my earlier rudeness not acknowledging you properly... How can your maids serve you?"
