This is a Professor Layton and Durarara! Fan fiction.

"So, what's the answer to the mystery Professor?" Luke asked expectantly.

"There is no answer Luke." The Professor said calmly.

"What do you mean there's no answer?!" Luke shocked.

"Calm down Luke, I meant there's no answer because the mystery doesn't exist. Isn't that right Izaya?" Izaya threw up his hands in mock surrender.

"Wow, you really are as smart as they say." He remarked.

"That was a really mean thing to do!" Luke snapped.

"Now Luke, don't be rude. I'm sure Izaya has a good reason behind his actions."

"I don't really. But you guys love solving mysteries don't you? So, what's the harm in me making up one?" Izaya smirked.

"I guess you're right. But I would appreciate it if you didn't treat me like a kid." Luke complained.

"I have every right too. You're probably like 10 years old right?"

"HEY! For your information I'm 13 years old! You're like 16 right? You're not that much older than me!"

"Calm down Luke, remember that a true gentlemen always treats people with respect." Professor Layton advised.

"I'm flattered Luke. You think I'm 16? I'm 23 years old you know." Izaya smirked.

"Huh?! You're 23? Really?!" Luke goggled, his eyes wide. Izaya started giggling in his demented way, scaring Luke, but he'd never show it. It ended quickly though.

"Well, it's been great but I must be going." Izaya said walking off. Then he somehow go back to his world without anyone knowing.
