Chapter 1:

A bus full of high school students pulls up to the curb at Inchon Airport. The bus driver nods his cap to the airport staff. One of them who saw his nodding reaches for his walkie-talkie, and says some code to his crew. The airport staff rushes to the bus and asks the driver to open the luggage compartment, which he did with a push of a button underneath the driving wheel. As the staff helped the driver with the luggages, fifty-three students came out of the bus along with their teachers. They were your normal high school students, just like anyone else. But underneath their normal appearance lies monsters that transform and eat without remorse to their existence and humanity.

They are called transspecies, former humans who have transformed into mutated beings with horns and blades coming out of their bodies and head, extremely elongated limbs, and other unusual deformities. People can become transspecies by drinking a certain liquid found a remote sea cave off the coast on Jeju Island. When most people drink the liquid, it tastes like mineral water but, according to legends, it can also heal people from health ailments. Well, that "healing" healed them beyond the health ailments and made them into hideous beings of some kind. The public does not know about their existence but it is certain that the public should not know or learn about them..

As the students grabbed their luggages, the teacher coughed out loud. Students looked at their teacher and listened to his word, "Ok then. Before we check in, we are going to do a roll call. Just say here when I call you. Got it?"

Everyone said yes and he grabbed out a clipboard and a pen from his backpack and called out students' names. "Han Jinwoo!"

"Here!" Jinwoo called.

"Lee Jungsoo!"

The list kept going and once after they are finished, the group grabbed their belongings and headed into the terminal. As they were walking, the teacher stopped walking and turned around to his students. He said with a sinister grin, "By the way, make sure you got your bar supplements, otherwise this will not be a pleasant flight." Everyone checked their luggages and backpacks to see if they carried at least four chocolate bars in their belongings. Onlookers looked and thought that this was cute and childish, but for them, this is not child's play. If one of the students does not eat their chocolate bar, they will transform into a runaway, a transspecies who transforms beyond recognition and eat anyone, including transspecies, without any regard.

Han Sukgyu was behind of the group and Sohee followed him quickly. Sohee exclaimed with glee, "I cannot believe that we're going to Los Angeles! I heard you could see celebrities at the beach and in the city. Isn't it cool?"

Sukgyu replied shyly, "I guess so." One of his friends jumps behind his back. "Oh come on, Sukgyu. You were really excited to go and maybe you meet that gangsta Ice Cube in Hollywood! You said he's your favorite. We're coming straight outta Korea!" he laughs with Sukgyu.

Sohee's friend comes at them with her earphones and eyes on her phone while sarcastically joking to him, "Yeah, straight outta your mouth." His tone changes, "Hey Junhae. Shut up."

"Fuck you Jungtae and your shitty rap crap!"

Before blood spilled over a joke, Sukgyu enters, "Hey guys, calm down. Look, we're going to Los Angeles for a "field trip" and then after that we'll split up and look for ourselves." His mouth formed into jaws and glazed at Jungtae and Junghae, "Got it?"

They hurried up to their group before they got lost and the teacher told everyone to split up into 4 groups during their time at the airport once after passing security. Sukgyu, Junghae, Sohee, and Jungtae came together easily and decided to head up to the food court. While waiting for Junghae and Jungtae to order, Sukgyu and Sohee talked to each other. Unlike most students and her teacher, Sohee is the only human student in her school. Ten months went by ever since Sukgyu's transformation and Sohee is finally glad that he came back. She was worried about him for so much since she discovered Sukgyu's trait and his monster form. When she first saw him, she was scared of him yet felt thankful for saving her life. Sohee saw Sukgyu crying over his beast form and hugged him. Sukgyu never felt the same as like most transspecies: no guilt, no conscious. For him, this was an eye-opening moment for him for he thought he would never be human but rather a monster. Thanks to Sohee's heart, Sukgyu let go of his predestined thought of forever being a monster and focused on Sohee from now on.

"You know Sohee, it's been ten months and I just want to say that I… uhm."

"Yeah Sukgyu?"

Sukgyu blushed, "Well, you see…"

As they were talking, Jungtae interrupts the two, "Hey guys! There's a change of gate and our plane is about to leave. We gotta go now!" Jungtae screamed. "Meet up with Junghae at gate 33. I'll catch up."

"Shit," Sukgyu said, "Sohee we gotta go. And here's my gift."

"Thanks," she replied. She opened up and was extremely happy and put it in her pocket.

They were rushing, sliding, and jumping over to be at gate 33. And once they got there, they meet up with an angry teacher and his foot tapping. He said, "Where were you?"

"Sorry Mr. Kim." They all said.

"Forget that, we need to board now."

They barely boarded and managed to get to their seat, much to the chagrin of the passengers and their group. As they find their seats, there was a guy behind them, looking at them suspiciously. He noticed their extensors popping from their backs, especially more pronounced from Sukgyu. He whips out his phone and quietly calls his team. "Hey. Be on the lookout for four teenagers on Flight 113. Hannibal out." After he finished his call, he tried to hide his camera inside his jacket, but he bended forward too much and the "snap" sound was heard. One of the flight attendants came up to him and asked him to turn off his phone; he promptly did so, but managed to hide his camera in his jacket without notice. Or so he thought; Mr. Kim saw his move and is very wary about this human. But this human was different from what he expected: a young sky marshal with a badge and gun.
