History
The inventor of the Peerless Transformation Style was an adventurer who wanted to overcome danger without relying on the heroes so he founded the School.

It’s a legendary style that is said to have never lost on the battlefield. The style has left its mark on the histories of countries around the globe. Just like the Four Summoned and Seven Star heroes. However, half a century ago, internal discord caused the death of a majority of its practitioners. Those left all swore to never pass it on.

The Hengen Musou style was brought to ruin through internal discord caused by such a genius. There was a certain talented individual who came under the impression that he was the one worthy of ruling the world, and their teachings forbid such ways of thought.

The last remaining practitioner said that the style was no longer needed in this world, and planned to take it to the grave with her. But after being helped by Naofumi, she decided to pass on the legend for the sake of the world.

Abilities
There is no specific weapon with Hengen Musou Style. Hengen Musou Style is an all-around combat art which utilizes a wide variety of weapons to fight different kinds of enemies.

One technique of the Hengen Musou Style is used beat people with high defense. However, a reversal technique also exist. All you have to do is assess your opponent's internal spirit and inject your own magic power to cause a disturbance and make your opponent’s magic power run wild. To reverse the technique you just have to redirect the power outside of your body before it begins to get out of control.

Musou Kassei
A technique for sucking in Chi from the air. It’s best not to keep Musou Kassei on for a long period of time. The body won’t hold up. It’s a sort of boost skill.

Mussou Kassei artificially creates something similar to SP. When that’s in place, Magic increases in effectiveness. But without SP, Magic has its limits.

Chi
Chi is the basis for Hengen Musou. Like magic, every person has Chi in their bodies. Some, however, have more talent than others in manipulating it like Rishia and Atlas. Rishia is special in that she can learn almost if not all of it and is considered to be a talent is only found once every 100 years. Atlas has innate talent and perceives the world around her through sensing Chi. The Four Legendary Heroes all have irregular Chi flows which disallow them from using Hengen Musou. However, they can counter Hengen Musou if they train their Chi properly.

Peerless Activity
Peerless Activity is the time period in which Chi is actively being used. Eclair is only able to use it in bursts while attacking or avoiding while Rishia excels at maintaining peerless activity for a extended periods on something like a low output but she can also use it in bursts. In essence it's like an ‘Overdrive’ skill or attack in games giving the user an ability boost for a certain time.
