Chapter 1
On the continent of Rara, The royal capital, there was a mansion where the two heroes, Akira and Sumi lived. Akira and Sumi were summoned to the world of rara from Japan with 4 other people and were asked to defeat the demon king. Unlike the novels they had read, the king of the human race immediately kneeled and had asked them to save the kingdom.
The demon king controlled a large amount of the land. He had amassed demi humans and demons to fight for him. Some were loyal to him while some wanted peace after the demon king was defeated the demi-humans, demons and humans signed a truce, stating they would live in harmony. After a defeat, all the demons were turned to demi-humans by the help of a forbidden magic, which changed the way demons thought and made them cooperative.
Of course, some were unwilling, they were not executed by the heroes instead they gave them a home to live in. As long as they didn't cause trouble they were free to do any legal things on the continent of Rara.
The new king was one of the heroes named Adrian. He was one of the heroes with the power of physical enhancement. The two other heroes were named Arman and Alok. Apparently, they were twins and they had a magic called twin magic which doubled their attack power when they both are within the radius of 10 meters.
The sixth hero was named Akane, a person with a petite figure but the most powerful assassin.
After the demon lord was slain, Akira and Sumi married each other and had 3 children, which they named Rami, Marquis, and Martin. Rami and Marquis were powerful but the most strange one was Martin. He was now 3 years old and he could use holy magic as if it was nothing. At the age of 2, he saw a spear of gods and actually created a spear of gods with the power to destroy stars.
All the 6 heroes gathered again to discuss what they should do with the spear when the spear moved on its own and entered inside Martin's body. Since, then Martin's power were blocked by the god of this world who informed them that Martin had power beyond anything else, even her. She had actually sacrificed half her divinity to seal away Martin's power till he was 5. But still some of his power couldn't be sealed and that some power could destroy everything. He was already mature for a 3-year-old and pretty much-understood everything. He even understood how to read people and did everything very carefully and was very cautious of people.
Akira and Sumi had taught him not to use his powers carelessly (what remained after sealing his powers) and Martin understood most of what they said and didn't use his powers. The goddess had to put her seal till 5 so he would be even more mature and not destroy everything.
This is the story of the child, named Martin who could do everything.
