Stone Lee is the descendant of Rock Lee, meaning he has very little to no chakra. Throughout his youth he was forced to rely on taijutsu, growing up in a world of chakra was tough. He was often put through other tests, those that excluded genjutsu and ninjutsu. Instead he went through weapon training and hand to hand combat, with ridicules from other students. He is fairly dangerous with weapons, probably because of some family lineage. However, Lee would rather use his taijutsu to decide a battle. If that fails the weapons would have to come in.
He never met Rock Lee. He died many years before Stone was born. Older villagers tell him about Lee, and he figures he was a brilliant man. Stone doesn't speak in contractions, he speaks much like Lee did. He's been told of the weights, and has adopted that method. He uses them on his arms as well, making them stronger. They weigh 100 pounds each. Stone was also told by many of the drunken style. He tried it at the young age of 12 and ended up just being drunk and having a bad hangover. If he gave it a few more years it may have worked, but he hasn't attempted it since. He has always wanted to open the gates he heard so much about, but it's a supposedly limited technique. No one has taught him anything of it and he passed the Chuunin exams without it, maybe he doesn't need it after all. Speed, power, and weapons could be enough.
His strength was proven at the Chuunin exams and he is no longer mocked for the little chakra he has. He's a chuunin now, and a smart one at that. He passed all of his tests during the exam. Now he is awaiting an assignment from the Hokage, whether it be missions or as an instructor. He hopes to become a Jounin and lead genin who have great potential, but he doesn't plan on going higher than that.
