I had a breakthrough idea for a manga.
An unnamed world has been at war for as long as man can remember. The world can be compared to a modern day Sparta, as kids are taught to fight at young ages.
In the City of Peace, children strive to become Mercenaries, whether they want riches upon riches, or want to achieve a dream. In the Peace Academy, students are taught the ways of battle. Classes on swordsmanship, archery, hand to hand combat, even elemental manipulation exist in this school.
Within the body exists a complicated circuit of energy that I call Energis atm. Every part of the body is meant to deal with a certain type of Energis, the palm deals with Elemental Energis, by simply looking at the marks on your hand you can tell your Elemental type. The fists and the feet are Break Energis types, meant for hand to hand combat. The Energis system is what I like to call Naruto's chakra system done right. Energis types differ from the tip of your head, to the end of your big toe, allowing for mountains of weird powers and different type of fighting styles.
The Peace Academy has always held a rivalry with the Demise Academy in the neighboring city of Demise. Weakling, Rain Doku, is known as the weakest student at the Peace Academy. He can't hold a sword up, even with two hands, lacks the accuracy for ranged attacks, and his elemental affinity of Water is nothing but a trickle.
However in legend exists 8 Kings, blessed with the power of manipulation of their element to an extreme. Unknown to Rain, he is one of these 8 Kings, the King of the Seas. Of course, he doesn't awaken these powers overnight. With the Mercenary exam coming up, Rain must train his powers, in hope to become a Mercenary, and achieve his dream of being number 1 in the academy.
Of course, the world starts off small, but gradually zooms out into the world, as Rain becomes a mercenary, meets new friends, learns of new Energis, and a hidden danger within his school. It starts off as a school manga, but gradually turns into an epic battle for survival.
A drawing of Rain is coming eventually.
