The moment she questioned the boy's reasoning for getting invited, his hand slid from his pocket to the lining of his trench coat to move it over to the side. She was met with the sight of the line of beaten and scratched up ultra balls lining his belt loops. They was battle hardened for sure, having seen a multitude of battles over the years. Obviously this guy was a Pokemon Trainer of sorts. His hand let go of his trench coat, letting the red leather fall back into its original position to conceal his arsenal of Pokemon.

''I'm the best trainer from the region I'm from...'' He rubbed his neck, ''In hindsight, that's not saying much around here isn't it?'' At this point, his opening theme kicked off as he started to introduce himself. ''Actually, let me rephrase that..'' He cleared his throat, a little bit of streak of intensity sparking though his brown eyes, ''I'm the most feared trainer in my Region. *The Tyrant* Is the name a lot of the small fry in the league call me. How childish is that?'' He let out a faint, cold chuckle at the thought of people actually calling him that name unironically. If anything, it was more of a show name. 

"All jokes aside..'' He outstretched his hand over to her, offering a handshake to the purple haired girl. With closer inspection, the boy began to notice more and more about the girl's looks. She wasn't that bad on the eyes, plus she seemed pretty intelligent. If anyone was going to make a good ally to have on this island, this strange girl would probably be the one.

Although she was in no place to play detective, based on his looks he was a trainer of course! Then again those beaten up pokeballs could just mean he's dropped them to the ground multiple times or something along lines of it. He didn't seem much like a clumsy guy. 

Ah, she figured he was a trainer with a formidable reputation, perhaps a champion? It was from the look he had on her eyes that really said something. "The best trainer is quite the title, or I meant to say the Tyrant. That's an intimidating name," She tilted her head, having her high ponytails bounce with the motion of her hair.

Before she took his hand, she got up from the chair looking up at the taller guy. "I'm Rita, it's an odd time to meet but it's a pleasure to meet you," She grinned, and in return grasped his hand and firmly shook it. "As for me you're out of luck if you're looking for a trainer to battle with." Rita joked, parting her hand with his.

Quinton immediately cringed at the mention of the terrible name that was given to him from his home region. She didn't need to do much detective work to nail his identity right on the head. He was the champion of his region, well, the former champion of the region. We resigned in the hopes of finding stronger trainers to crush under his boot.

Maybe it was best to get on this girl's good side, ''Nice to meet you too, Rita.'' His gloved hand encased itself over her fragile, feminine hand. It felt like almost with one wrong movement or squeeze, her hand would shatter like glass. Carefully, but firmly; he proceeded to shaking her hand, "My name's Quinton.'' A forced smile became visible on his face. Afterwards, his hand retreated back to his pocket, his "Smile" Quickly fading. 

The man scoffed at the idea of battling the girl. She looked too weak to even train a pokemon, much less battling with one. Usually the boy would find himself making a smart, hateful comment to belittle the female, but he held his tongue for now. Instead an awkward silence filled the air between them for a moment. His eyes slowly diverted from the girl to her glowing laptop behind her. ''So erm..'' He cleared his throat, ''what are you doing here this early exactly?''

"Quinton! I see!" Rita nodded, although the library wasn't the brightest at this time, she noticed his smile seemed to reflect that as well. Perhaps small talk and meeting didn't seem much of his forte. On top of that there was sort of an awkward silence towards the end, she wondered what was in his mind until she saw his eyes shifting to her laptop.

"Oh! Actually I'm working on my dissertation at the moment. This one focuses on the ecological, economic and social impact of climate change. I figured coming to this island could help me with my research on that. Especially looking through, Sigford Island has a huge variety of biodiversity here and it doesn't look as if it's too impacted by... Ano.." Rita puffed one cheek and tapped on it. She gave off a light laughter sheepishly scratching the back of her head. "My bad I tend to off in a tangent like that."
