The Invasion 2: Itazura's Revenge

Conversion.

After Lillian have her consent to be converted, her and Charles ventured through Cantinar into a deep forest. A massive lake is said to be watched over by gods, and whoever swims through it will be judged to become one of them. Of course, Charles thought Lillian would be a perfect choice, since she helped save the world and all. 

"And here we are Lillie!"

"Oh my..."

The lake was glistening, even though it hasn't been touched in years. The water was blue and completely see-through, so much so that no form of life was in or by it. Charles and Lillian were on a cliff. The latter had to jump off a height to see if she was brave enough.

"Okay, now why do I have to jump? Why not just go in?" Lillian asked.

"Because you need to be brave." Charles replied.

"I'm just gonna go-"

She was grabbed by Charles.

"Jump"

Lillian's eyes widened. She was afraid, but she wanted to convert.

"No!"

"Do you want to convert or not?"

"Yes, but not jump!"

"You have to."

Lillian sighed. She walked to the edge and looked down. Then she panicked and ran into Charles' chest.

"I can't do this! I'm scared!"

The next thing she knew, Lillian felt a strong grip on her body. Charles has picked her up and was marching toward the end.

"Don't you dare-!!!"

Her threat was fruitless. By the time she finished talking, Charles had thrown her downwards. Lillian didn't even scream, she was too scared to.

Lillian plunged into the water, which knocked her unconscious. Charles watched from above as the water began to glow brightly.

It was working. 

Lillian was now one of him.
