Infinite Potentials [An Elsword Isekai Fanfic]

Prolog - Chapter 0

I wake up and get ready for school as always. I meet my older sister downstairs and greet her.
"Good morning, sis", I say.
"Oh, good morning", she responded smiling.
"I already made breakfast, I'll be going to school now, see ya' ", she pats my head and leaves.
I eat my breakfast and leave. My parents already left to work. I finished my breakfast and go to school.
My friend Zen greets me with a tackle.
"Hey, Ryu! How are you?", she says energetically.
To which I respond with "Hey, Zen! I'm fine and you?".
I hug her and we continue to walk towards the school.
"I feel great! Wanna play this game you showed me yesterday again?"
"Of course! I love 'Elsword'!", I say.
We talk about a few things we could do while we play and about homework. As we arrived and entered the classroomi greeted a few more friends before class started.

School was kinda like always, a bit annoying but not that much. Though I didn't really understand math, I'll just ask my sister if she can help me. She's really smart, I think. Even tho' she's kind, she can be really scary sometimes. Zen really likes her and they get along well. Anyway, I walk home home separate from Zen on the way. I reach home and make something to eat for myself. My parents aren't home most of the time during the week and Yui, my sister, comes home later than I do as well. So I learned to cook, but my sister can do it better. I make some dinner and eat. I save some for my parents and Yui, and do my homework for now.

After a while Yui arrives and I ask her if she could help me with math after she's done eating. She agrees and pats my head. Some time passed after Yui helped me with math and I boot up my PC to play some Elsword with Zen. Yui decided to watch me play, for some reason she seems interested in what I play in my free time. Hm... Something's not right, the game takes longer to start than usual. There's no update as far as I know. The game finally starts and I log in... Huh? Did my PC just crash?
"That's weird, it never crashed before when I logged in!",
I'm kinda sad and angry. But the screen turn on again. My sister and I stare confused at the screen. A text appeared.
"Adventurers! We call you forth to defeat the Evil that has come upon our world, terrorizing everyone! Please save our world and become the Heroes we need!"
We're both really confused about the text and suddenly a portal thing opens in front of the screen. It sucks us in and everything fades to black...
