Serina

A few days later, after I came back to my pocket dimension and continued my training with Serenity.

In Jin's Pocket Dimension, Jin and Serenity is taking a break on their couch after finishing their trainings for the day.

"hey" Jin says to Serina, trying to get her attention

"yes, Creator?" Serenity responded unexpressively.

"your name is a bit long to pronounce, are you fine with that though?" Jin asked Serenity about how long her name he gave was, since he came up with it on the spot, he wasn't sure she'd like it.

"I like the name Creator Jin gave me. But if you want, Creator can try and shorten the name" Serenity responds with a suggestion.

"Well if it's like that, then I've got an idea! Instead of shortening your name, I'll give you a nickname, how does that sound?" He said, hoping for her to agree to the idea,

which she just nods to.

A name immediately came to mind, "Then your nickname will be... Serina!" He exclaimed.

"But that's only one syllable less, and isn't it more like shortening the name rather than a nickname?" Serenity with a cold yet confused tone, trying to know if her name got shortened or if she got a nickname.

"oh pfshh whatever, atleast it's cute" Jin said, replying to her, which she slightly turns her head away from him.

"So from now on, you will also be refered to as Serina, understood?♪" Jin said joyfully, his legs swinging back and forth.

"Understood".

After that, Jin has been calling her "Serina"

"oh hey, just noticed, but the goop from your eyes is almost gone huh?" He points out to her eyes, which was gooping out black liquids before in the past few days.

"Yes, it's all thanks to the training I had with Creator Jin."

The two of them continued having peaceful conversations like this and continued their day to day life.. constant training each day.
