A city that had been standing since the era before the demon king's birth. The lives of the people were peaceful until the attack of the demon kings army. Countless villages were razed, pillage and many lives of the people had passed. Its was pure massacre.

But on this Kingdom of Blyken, had hence summoned a hero to save the humankind from destruction. For he, a young warrior had encounter dangerous obstacles , face powerful monsters and...

"...defeated the demon king and saving humanity. I have to admit,you really did summoned a new hero to defeat the new demon king. Huh."

"Actually...."

"Oh, a batch of heroes right?"

"..."

"Heeh."

The princess was lowering herself down while the knight glared at the boy with hostility. Even people wouldn't be this arrogant against a royalty, exept this boy. He just mocked the princess without batting an eye, in fromt of her.

He was once a hero who was summoned by into this world. Family, friends, he was force to leave them and had to sacrafice his life, for the world he didn't belong to.

Carrying on a huge burden that was force to take, he had faced life treatening battles and crawling to the demon king's castle to fight the ruler and save the world. Being tricked by the people he put faith into, he suffered his life, stucked to a world where no one who care to. How could he kind-hearted?

At the castle, a majestic building decorated with beautiful garden. Guards were station at the entrance, wore shining metal armor that gave off a strong feeling to any bystanders.

As they exit the carriage, they were greeted by a line of people who wore matching clothes as they stood at the side of them. Maids and butlers gave respect to them.

"Welcome back, princess and sir Kael."

The servants gave bow to them as some of them gave curious stares at the boy beside the princess while the others were gloomy to see the boy. The boy gave off a dissastified look at the castle as he want to puke while seeing it.

In the room where people stood, on a throne was a man with age that has passed 40. He look below to a boy while making a pained expression. There were nobles and knights station beside him and three people who wore different clothes that doesn't belong into this world.

(So they are the new heroes that the shitty king brought. They all belong to my world then.)

"So you ret-"

*Glare*

"..."

The man who sat in the throne wore a sad expression as he made the boy pissed. He was a king who lead the invasion to defeat the demon lord but he could not be even arrogant in front of the boy.

The boy who had slain the demon lord, save the world, and even protected his daughter from certain death. But he stared at the king, he bore an arrogant attitude as he cursed the king.

"I don't care what you say now fucker. I came here for one thing, money."

The guards became pissed as he spat out insults at the king. But they could not even move at the boy who glared at them. He was a boy who they can't even defeat. As he move his eyes around the throne, the boy stared at the princess who sat the side of the king. She was the princess that he saved at the time.

"Hey, once this is over, don't you fucking dare to come for me again."

After he spat out the words, a young man couldn't take it as he charged at the boy. The young man was one of the heroes who came from the other world.

He unsheath his sword at the boy and trust it towards him. The boy only stood there as the swords was commimg towards him. But something unbelieveable happened...

In the eyes of the young man. The boy in front disappeared and then his sight then became blury. He was being gripped with a single arm while the boy's other arm was crushing his skull. He then let go, as he gave the young man some time to breathe.

"If you charged recklessly, you only get yourself killed. If you want revenge, get stronger to kill me."

The boy gave a lecture to the young man. The young man was a hero who was summoned in the other world. He even had cheats that was blessed by the goddess in this world but in front of the boy, it was useless to him.

As the young man regret that he couldn't even make the boy flinched with his cheats. As the boy stared at the young man, he gave a smile at him.

"I came to train you. Use the cheats and my teachings to kill me. If you can't even gave a proper killing intent, how could you even defeat the demon king?"

The young man was shocked that he has to kill a living being. He had been raise in a peaceful world and have to soaked his hand with blood. The boy tapped his hands at the shoulder as the young man stared at the man.

"I will help you, beacause i'm a former hero. My name is Tomori Haru, nice to meet you big bro."

(The italic had change his language in that part.)
