Nature of the Seven General Lords

Undine stood up and entered Zach's body.

"..." Zach stood still for a few seconds and asked, "Can you speak something?"

[Umm… my name is Undine.]

Zach turned to Asmodeus and asked, "Did you hear that?"

Asmodeus shook her head and said, "To me, it feels like you are talking to yourself."

"Undine, come out of my body."

Undine came out of Zach's chest and kept the rest of her body inside him.

"How do you feel?" he asked.

"I feel the same as I do when I am one with the water. Right now, I feel like I am one with you. Your heartbeats feel like my heartbeats, and your body feels like my body. I don't know how to describe this feeling since it's my first time entering someone's body."

"Can you enter and leave my body without my permission?"
