Chapter 1: Sudden Appearance

Chapter Text

Five weeks before the crash.

 

“Captain! Captain!” Daisuke screamed, swinging open the medical room door.

 

Curly and Anya jumped in surprise, their discussion prematurely ending upon the arrival of their younger co-worker.

 

“What is it, Daisuke?” the blonde haired man asked, confused.

 

“T-There’s like… a dude! On the ship!” The young intern exclaimed, flailing his arms around.

 

Curly looked at Daisuke incredulously, while Anya seemed equally confused as she began to speak.

 

“Daisuke, have you been taking pills-?”

 

“No! I swear to god! Come on!” the young Filipino man said, waving his hand towards himself as he exited the medical room.

 

The two crew members anxiously followed Daisuke as he led them to the lounge, where Jimmy and Swansea were standing over a seemingly unconscious man.

 

“Jim? Swansea?” Curly asked, making them turn around to face him. “Who’s this guy?”

 

“Dunno.” Jimmy answered rather uselessly.

“No clue, the teenybopper was just chewing my ear out in front of the food machine when this guy popped up outta nowhere.” Swansea replied. “Toppled over the table.”

 

Curly and Anya made their way in front of the unidentified individual, to get a better look at who had magically appeared. He was a tall individual with white hair, wearing all black clothing and a black blindfold over his eyes. The table was also in fact flipped over to his right.

 

“He’s breathing.” Anya said calmly.

 

“Good, but he’s still unconscious.” Curly affirmed, nodding his head. “We should take him to med bay.”

 

“Aren’t we gonna ask why the hell this guy’s here?” Jimmy questioned, raising an eyebrow.

 

“I gotta agree with Jimbo, it’s not everyday gosh darn day somebody pops into reality in front of your eyes.” Swansea stated, giving a downwards glance to the newcomer.

 

“We have to make sure he’s in good condition first,” Curly claimed. “then we can see if he knows.”

 

“Okay, but like… how?” Daisuke asked.

 

No one had an answer to that.

 

“Maybe this is that science stuff you keep yappin’ about.” Swansea guessed. “Phantom teleportation, or whatever.”

 

“Quantum manifestation!” Daisuke giddily responded. “It’s where something naturally appears into existence due to quantum tunnelling!”

 

“This is why I say you’re talented for all the reasons.” the old man sighed.

 

“His pulse is steady.” Anya confirmed, resting her hands in her lap. “But you’re right, Curly, we should give him a check-up just in case-”

 

The man suddenly shot up, getting into a sitting position. This made Anya shriek in surprise, Swansea lean back in shock, and startled Jimmy and Curly. Daisuke had his eyes wide open but seemed unable to move.

 

“Uh… hello?”

 

“Who the hell are you!?” Swansea yelled.

 

“Swansea! Stop screaming!” Curly exclaimed, before tilting his head back towards the individual. “Do you know where you are, sir?”

 

“A spaceship.” they answered a bit quickly. “I mean- I think?”

 

“Correct, you are on the Tulpar, interstellar space freighter.” Curly explained, somewhat surprised that this person had guessed so early. Well, they had just appeared out of nowhere according to their oldest and youngest crew members, so what would he know?

 

“How are you here?” Jimmy asked quite abruptly.

 

The man seemed pensive, they had quite an unbothered expression on his face, but Curly couldn’t tell what his eyes told behind that blindfold.

 

“No clue.” they answered.

 

Jimmy huffed, not convinced, while Curly and Swansea were still eyeing the peculiar character. Anya had managed to get her breathing down, and Daisuke still looked unbelieving.

 

“What’s your name?” the captain finally inquired.

 

“Satoru Gojo.”
