"You have a tail!?" exclaimed Merylin could hardly believe it.
Niken herself also looked blank because she didn't know that her magic circle could give her a mermaid tail. At first, she thought her magic circle would cover only her face so she could breathe and talk in the water. Who would have thought she even had a tail?
"Niken, who are you, really?"
Niken scratched the nape of her neck that was not itchy awkwardly. She was the Princess from the Nishian kingdom and sole inheritor of Time Master, but she was unsure whether this world had Nishian island.
Merylin swam closer and held her hand cheerfully. "From now on, I will adopt you as my sister."
"Ah?"
"I wonder who is older? How old are you?"
"Seventeen?"
Merylin smiled broadly at that. "From now on, I will be your elder sister. Come on, follow me."
