MTL - League of Legends: 700 Years Later - Chapter 43 Hero and the five elements said

This is a story about a legend, of one that can never be forgotten.
Summer, first time down the mountains in 16 years, after being raised by his 3 masters and Fairy sister.

‘Why won’t you follow the Rules of society?’ The rules are the tool made by the strong, so I follow my own rules.

‘Why won’t you just use your brain instead of your brawn?’ Idiot! Have you ever seen anyone use their brain, to get back at an ant that bites them!? No, they just casually step on it.

‘Oh, everyone says you’re a first-class beauty huh?’ well, I’m sorry but even you are not qualified to be my wife. Only a ‘Summer class beauty’ is worthy enough!

‘My enemy is sick?’ Oh, don’t worry, even if you’re on your last breath and I feel it’s beneath me to slap shot you dead. I’ll just fix you up and then beat you!

‘Who am I?’

“I am Summer in the spring, the autumn, and the winter, I’m the world’s first above the heavens!”

Follow me, Summer Day as I step by step become known as the world’s first master, the world’s first doctor, the world’s richest man…… a lot of other world’s number one, but most importantly, The worlds happiest man.

He was not a human since no human is aware of himself even before his birth.

He has no blood and no heart, but emotions?

He does have feelings, but can he express them?

Why was he called a Devil’s Spawn at his birth?

Why did they cut away his arms and a leg?

Why did no one ever visit him for years?

And why does this emptiness... feels so... just so familiar?

Why does the Void feel so... full?

Who is he? Or rather... What is he?
