Another Author's Note:
As a unexpected decision, I will splits the story in two parts: A and B.
A will represent Ahri's point of view, while B will follow on Master Yi.
Further I will write Chapter 1 on Ahri's point of view.
Chapter 2A: My first days as a champion (Training)
When Ahri woke up, she was surprised to find herself in someone's house. She didn't expect that from the breeze of the previous day, someone would find and bring her to his or her home. She was still cold from the frozen weather, but somehow the futon that she was resting on had warmed her up a bit.
-"That futon is specialized for winter. It warms the user constantly so he or she doesn't feel cold. It feels warm inside of it, doesn't it?" a voice said from another room. It was a man who said that.
Ahri decided to leave the room only to find a man. He was in his armor, but she found his helmet funny. She tried hard to not laugh, as she can't make fun of someone who saved her.
-"Umm, sir... I appreciate that you saved me, and I'd like to thank you. If you excuse me, I'll leave your hom-"
She was stopped by the man, it was clear that she wasn't fully recovered to go. She almost tripped.
-"Drink. It's medicine for cases of hypothermia."
She drank the medicine that the man prepared for her.
-"Ahri, a wolf who turned human by a mysterious man in robes, who seduced men in order to steal their life essences and whose purpose of coming to the Institute of War is to retain her humanity. I'm not wrong, right?"
-"How did you…?"
-"Don't ask. These elder summoners always keep track of people like you. They gave me a report file containing everything about you."
-"And you are…"
-"Master Yi. I'm one of the tutors in the Institute of War. Weren't you going there?"
Her head lit up. She remembered that she was going there to find a method on how to retain her humanity. She always wanted to be human, and the chance of that dream becoming true was in that place.
She examined the man who attended to her injuries: he looked young, although he had grown a large beard. A thought crossed her mind: she could seduce this one so as to steal his life essence. But as she thought of this, she broke down and cried. Master Yi realized the reason why she started to cry.
-"The regret of ending a lot of lives only for one's self. I know that you didn't want to end their lives. You came to the right place. I promise you won't hurt anyone for real."
The bladesman offered a handkerchief to Ahri. She took it and wiped her tears.
-"If anything comes across your mind as a doubt, don't hesitate to ask me. Now, if you don't mind, we must get to the Institute of War."
Her essence sphere materialized. Yi apparently remembered something when he looked at the sphere.
-"So that's your source of magic? I already know who I shall send you with."
She thought that the trip was going to be long, but it didn't take more than a quarter of day to get there. Master Yi and another person bowed to each other. This person was a woman, but had a horn on her front. She also had goat-like legs.
-"She is Soraka, the Starchild. She's a mage, like you."
Ahri quickly bowed to this person, but she responded with a chuckle.
-"Don't worry about formalities. You're the first person of the year to be saved by Master Yi, being the third one in total. You are just lucky to meet him first before heading into the Institute."
Ahri blushed. She was saved, but didn't expect a first to be a man. She didn't think about any reward that was going to give to Master Yi. Obviously she will have to give him something as a sign of gratitude.
Master Yi came outside, and told Ahri she was late for her first training. Soraka told her that if she had any trouble, she could come and see her before going inside.
When they got to the training field, another man, who had marks all over his skin, was waiting there for both of them.
-"Ahri, please meet Ryze. He'll be your tutor for the rest of the day. He specializes in training new champions in the Institute, especially in the subject of magic."
A feel of shyness crossed Ahri. She hid behind Yi and hid her face. Ryze laughed a bit.
-"Don't worry, new champion. I don't usually receive this kind of greetings, but I don't mind."
Master Yi chuckled. He gave her a push and said not to worry about him. Someone apparently called Yi as he was leaving the field.
-"Another summoner conflict Ryze. We shall reunite later with Soraka for lunch."
As soon Yi left, Ryze summoned some training dummies and asked Ahri to hit them with her magic. He wanted to test the level of her magic.
So this is how her days as a champion started.
