"Can you please tell me why you would even consider that Mister Emiya? You're quite handsome, so even if you aren't talented, I'm sure the guild can introduce you to a god or goddess willing to accept you"
There were generally 2 distinguishing characteristics gods and goddesses consider when making their familia.
They either look at a child's potential, hoping they will be able to grow strong and raise their familia.
Or they look at a child's beauty, wishing to form a bond with mortals pleasing to their eyes.
Though there exist situations that don't fall into either of these 2 categories, for the majority, this is what decides a request to enter a familia.
"Even discounting your appearance, there are plenty of roaming gods and goddesses in Orario who are looking for children to join their familia"
The guild keeps a record of all the gods who have descended and keeps a list of recruiting gods in order to help new registrants start out. These services are what caused Free-Class registration to become so rare.
Even if one was at the bottom of the barrel in all aspects, they would eventually be able to find a familia willing to accept them.
But even though Eina's propositions and arguments were well reasoned, Shirou still refused, looking towards the half-elf with conviction she would never expect from a newbie adventurer.
"Again, thank you for the concern, Miss Eina. I appreciate that you would go so far for someone you've just met...however...I know full well what lies ahead of me. I won't back down from this"
Eina faltered seeing Shirou. He exuded the radiance she had only seen in high-class adventurers she had met during her work.
She couldn't explain why. All of her experience was telling her that this was wrong. But Shirou was somehow able to convince her with the natural air he exuded.
"....fine. I'll accept your request for Free-Class registration..."
Seeing that he was able to convince the stubborn half-elf, Shirou wanted to thank her for conceding, but Eina cut him off.
"However!- I'll only accept on the condition you hire me as your advisor. No one else"
"I can pay for the service fee for now, and you can just pay me back over time"
This was how far Eina was committed to keeping adventurers safe. Even if it came at her own expense, she was willing to do so if it meant their safety.
"I'm not handling any adventurers at the moment, and since the guild scales the fee depending on how many adventurers an advisor has, it won't cost much so there's no need to worry about-"
But before Eina could continue laying out reasons to have Shirou accept her as his advisor, but Shirou immediately cut her off.
"I accept! I accept you as my advisor Miss Eina!"
"Eh?-"
At Shirou's quick acceptance, numerous things occurred at once.
Eina was left stunned, this was the first time anyone had been so quick to take up her teaching.
Some nearby adventurers tripped at hearing Shirou accept the feared Eina so quickly.
Misha coughed in surprise but was also smiling mischievously at the situation.
And Rose Fannett twitched in surprise, a small gesture, but to the always serious-faced wolf girl, it was a lot.
Eina was confused but came back to her senses. She suspected Shirou might've been eager cause he was attracted to her, so she immediately prepared to let him down gently.
"Mister Emiya, Im not-"
But Shirou had cut her off once again.
"Stuff like dungeon layout, pathing, and strategy. Composition and monster information. You'll be able to teach me that right?!"
Eina had assumed wrong about Shirou. He was actually interested in her teachings about adventuring and the dungeon. She was left stunned again, this was another first for her.
"U-Uh y-yeah. Those will be subjects I'll teach as your advisor..."
Shirou was quick on the uptake.
"Alright Miss Eina! We just need to finish a few documents and pay the advisor's fee right?"
Excitement was radiating out of Shirou at full force. Eina didn't know what to do and simply rode on the waves of the conversation.
"Yeah...just sign here and here..."
Eina went back to discussing the documents and procedures with Shirou but her eyes kept going back to the boy in front of her.
'He seems so excited...normally new adventurers are hesitant or too arrogant to take on an advisor...but he genuinely is interested. I can't sense any falsehood in him...'
Eina was experienced at reading people, she handled a lot of troublesome adventurers. She was naturally adept at pulling the reins in on such individuals, but Shirou was the first time she experienced no trouble in handling whatsoever.
'Honest and excited... Serious but... Cute as well... Mister Emiya is kind of like... A cute Red puppy...'
Shirou who was true to himself and excited at everything around him, like an excited puppy.
Eina had a natural disliking towards self-reliant and capable individuals, she tended to prefer those she could care for and help grow with her own ability.
Perhaps it was her experience caring for her sickly mother, or her beloved little sister. But Eina tended lean in such a way.
Seeing Shirou so eager to receive her instruction, Eina unknowingly began smiling at the future of herself and this greenhorn adventurer.
'I feel like... This time's going to be different... I'll make sure of it!-'
The tense atmosphere from before has dissipated, returning to the warm and gentle atmosphere it once was.
The onlookers couldn't help but be shocked at what Shirou had achieved.
The adventurers who adored Eina cursed and praised Shirou for bringing out a side of her they never saw before.
Misha's grin radiated a nauseating amount of mischievousness, but she silently hoped Eina would be able to heal from her past with this new adventurer.
Rose Fannett, jaded as she was, simply went back to her work. But deep in her mind, in a place she wasn't aware of, she prayed that these two would be able to achieve what she couldn't.
...
The afternoon had faded into the night when the processing of documents and fees had finished.
The guild hall became less crowded, as most adventurers tended to have their dealings with the guild during the day.
The guild staff began switching with those of the night shift. The city of Orario never rested, and though it wasn't as prominent, adventurers who delved into the dungeon at night were still a thing.
There were some hiccups in Shirou's adventurer registration, but Eina stayed by him through the process, though she was long overdue to clock out.
But eventually, it was finished, and Eina was seeing Shirou off just outside the guild hall's entrance.
"Thank you so much, Miss Eina!"
Shirou knew that Eina was staying late for his sake. He was aware that Eina went above and beyond what was expected of her, but it didn't make it less touching for him to see as he is the person who always remember favors.
"Don't mention it Mister Emiya. I'll be advising you now so it's the least I can do"
Eina wasn't honestly troubled by Shirou, she had experienced this many times before, so she simply replied with a genuine smile. Though she would have to make it up to her friend Misha for making her wait.
Shirou knew Eina was the type to see this as only natural, so he decided not to push it. Though he had one thing he wanted to fix.
"You're very kind Miss Eina, but can you not call me 'Mister Emiya'? It seems very awkward"
People used to call Kiritsugu 'Mister Emiya' and now refered the same name as him...
Shirou chuckled, he hasn't gotten used to being referred to as Shirou, usually previously people used to call him Emiya. Now calling him using honorifics along with his surname, seems foreign to him.
"Hm... I guess we will be working together now, so it would be best to get familiar... I'll refer to you as Shirou then. But I can't allow you to refer to me casually, we still have to maintain some level of decorum after all hehe"
Seeing the brunette half-elf chuckle to herself beneath the night sky. Shirou couldn't help but be mesmerized by her beauty.
Shirou couldn't call himself an expert in love. He had gotten his own heart played around just earlier that day.
But the lengths Eina went to for Shirou in the guild... even taking her out for a meal... not even Shirou would miss the signs.
'At least I hope so...'
Shirou began doubting his ability to gauge romantic feelings, but he would try his best to not be so dense.
'If I ever encounter someone who would fall for me...I won't accept them right away...I have to be strong enough first...'
Though Shirou doubted his ability to attract others, he didn't doubt he would someday fall for someone.
He didn't decide much on a course of action if he did catch feelings, only that he would focus on getting stronger first.
'Wouldnt want my crush to be some damsel in distress...'
Seeing the pondering look Shirou had on his face, Eina called out to him to bring him back to reality.
"Shirou? It's not nice to zone out when talking to someone you know?"
Hearing his name, Shirou snapped out of his concentration and apologized to Eina.
"S-sorry about that Miss Eina. It's a habit haha..."
Seeing Shirou's embarrassment, Eina couldn't help but internally comment on it.
'How adorable'
Eina's protective instincts were now running full-time for Shirou.
"I look forward to working with you Shirou"
Seeing the gesture, Shirou promptly returned it.
"I look forward to working with you too Miss Eina"
Thus after few days of his arrival at Orario, Shirou formed a connection with a figure who will help him throughout his journey. One who would stick by him through hell and back.
But that was beyond the knowledge of them both at this moment, as they stand covered by a hopeful starry sky.
