After thinking about the future Battle Styles Gravis would encounter for a while longer, he decided to get back to understanding more about the Law. He had found the Law of Heat, and he wanted to comprehend it now. The fact that it was a level two Law only meant that it would take more time to learn, and, right now, Gravis had nothing but time.
15 more years passed. By now, a total of 95 years had passed since Gravis had entered seclusion.
Gravis had spent a total of 30 years on the level two Law of Heat but still didn't manage to comprehend it. The Law of Heat didn't have any level one Laws as prerequisites to understand it, making it much harder to learn. After all, he had to understand everything at once without any kind of checkpoints along the way.
Yet, on this day, something happened.
No, Gravis didn't manage to comprehend the Laws, but someone came to visit him.
