With the death of our parents, he had to work day and night just to put food on the table.
Dropping out of college... famished... tired.
Life had always been hard on him. As if that wasn't enough suddenly monsters started pouring out of entities called 'dungeons', endangering his everyday lives.
Now if there are 'monsters' and 'dungeons', a 'guild' only follows doesn't it?

Aiden is an everyday unnoticed hunter who worked in a dungeon. Like a pebble by the side of the road most people didn't even notice his existence. He worked hard so that he could put food onto his table and pay his sister's tuition fees the cause being both of them had lost their parents at an early age. He had strived hard and raised his sister as if she was the only thing he cared about in the world. But his life takes an unnecessary turn of events with his little sister Yuna, at the very root of it.

Give it a shot and let me know what you think. My primary focus in this story would be the characters and the complex emotions they share between them in a seemingly magical world one can only imagine in their fantasies. The plot would mainly revolve around the world progressing for the end game and also the characters.
