After she has moved the boxes, she placed some weird doll on the shelf.
There are many kinds of dolls and there was at least a strand of hair attached to them.

she giggled

Trina went into her dorm. "Hello Aerith!" She moved some furniture but then she saw those dolls. "Um..what are these?"

"you wont be happy to hear it.better dont"she replied.

Then she played with her dolls again.

"Oh come on! I won't tell anybody! Are they like voodoo dolls?" Trina said while moving some furniture.

"owh, how do you know?
But these dolls are far better and stronger than any voddo doll that you can find"

She took a doll and place it on the table,muttered a few spells, then it moved.

"Just a lucky guess..." When Trina saw them moved she was shocked. "Wow! Can you make magic?"

"Its not a magic,"

She whispered to Trina

"There are spirits inside them"

"Sp-Spirits? Um...could you make a spell for them to move our furniture?" Trina said.

"maybe..I ever asked them to help me moved the boxes, but I'm not really sure about furniture"

Rioulu pluck Trina's hair and gave it to Aerith

"Ow!" What was that for?"

"I usually use people's hair to take part of their spirits, and put them in the doll.
Thats why they can move."

She put Trina's hair into a doll, and soon after that, the doll starts to move.

"So if I punched it I would hurt my self?"

"No, unless i use like 10 strands of your hair, then you might feel the effect."
she explained.

"However, it might consume your energy and you'll feel tired"

"These creep me out...Umm..so if I asked it to go get me a soda will it?"

"Yea!Let me show you"

She tell Trina's doll to buy a soda for them, she gave it money and it went off.

"we just need to wait here, it will come back soon"
