Somewhere in another dimension
A lengthy white train with black markings and red "eyes" is heading towards the timeline, which is pretty far away. Inside the train, a teenage boy with black hair, blue eyes, green T-shirt with American star, and black combat pants and boots.
"Miss, how far are we from Echo Ridge City?" the boy asked the waitress, who set his coffee down the table in front of him.
"We'll be there shortly. Please be patient." she replied nicely.
"Hey Dan, is it alright to take this train with... those guys?" the EM Wave being asked his partner, referring to the four multicolor demon-looking people.
"Oi (Hey)! Did you say somethin' about me! ?" the red humanoid devil irritatedly asked, putting his left foot on the seat next to the teenage boy.
"No, we haven't. And please don't get too close to me." the boy calmly said, drinking his coffee.
The red humanoid devil was pulled away by a blue humanoid turtle being.
"Sempai, where's your manners, treating our new guests in an ill-mannered fashion?" he asked, dramatically.
"I wasn't threatening 'em! I was welcoming them!" the red humanoid devil exclaimed.
A door opens as the old man with a cane, walked out to his usual seat.
"It's unusual to have new guests in our DenLiner, but at least he has a ticket." the yellow humanoid bear stated, crossing his mascular arms.
"Oi (Hey) Owner! Tell me this, are they supposed to hitch a ride like that other kid?" the red humanoid devil asked, walking towards him.
"Yes... they do."
"Ohh~ How so?"
"For those who can ride DenLiner with a ticket, they need to fulfill their quests in their contracts."
"What happens after that?" the red humanoid devil asked again as the old man lifted up his cane a little then gently slammed it on the ground.
"Then... we will return them back home afterwards."
"Huh? That's it?" the red humanoid devil tilted his head at his answer.
"Naomi... the usual please." Owner said to the waitress.
"Hai~ !"
"YOU'VE GOTTA BE KIDDIN' ME! !" the humanoid devil angered, slamming his hands on the table. "IT'S LIKE WE'RE TAKING THEM ON A FIELD TRIP! !"
"Aaahh!" the purple humanoid dragon threw a piece a cake at the red humanoid devil's face.
"Mmmm... Hey runt, do you have a death wish! ?" he fumed, rushing towards him.
"Momo-chan BAKA~ !" the purple humanoid dragon taunts him as they bickered.
"How is Tendou able to ride peacefully with these guys around?" the teenage boy asked himself, watching their little show with his calm, composed expression.
