Rima went home and also fell asleep.

Blue went to his emerald casing and fell asleep in that

The next morning, he woke up as Yugi, and waited for Rima. He pulled out his guitar and played Get out alive by three days grace.

Blue began playing Noctune of Shadows on an Occarina in his emerald case

Keiji

Suddenly some strange character with a polo shirt barrels in through the window. "Who- Who are you!" I ask, startled. He replies in a Jeff-ish tone, "Name's Zacktheking9000, but you can call me Zack."
"Are you... a serial killer?"
"Well, I do go through seven boxes of Cocoa Puffs every now and then, so I guess I'm a cereal killer... I'm ashamed."
"Not what I meant, dude."
"Oh, then no. The only one I've ever killed was Arkh Dai Marjin. But he was super evil..."
"Why do you remind me of Blue?"
"Blue? I'm 826 years old, have various special powers, and fight big evil. Who is this Blue you speak of?"

Rima walked to Yugi's house.

(I thought everyone lived in the same house.)

Yugi put down his guitar and teleported behind Rima. "Hewwo." He greets derpilly.

(No. XD)
"Woah! Don't startle me!" Rima said, jumping.

He appears in front of her and teleports them to his house. "You like horror movies?" He asks.

(What the nuggets went through my mind?)

Zack

In a manga I was reading, there was a familiar set of swords to it. Soul Edge. You see, when Blue was inside the emerald, I was Soul Edge's temporary rival. If I had a nickel for every time I stabbed that little f**k in the eye with my swords, ummm... Calculator error.

"Well, they wouldn't be my first choice of movie genre, but if you want to watch it, than sure." Rima said.

"Oh right, Ms. Potterlover." Yugi jokes.

"What is that supposed to mean?" Rima asked smiling.

"I know you know what I mean if you know," Yugi brainteases.
