Ryoma (竜馬 Ryōma) is a playable character from the Power Stone series.
Originally a samurai from a small island nation, Ryoma got tired of living in the island and wanted to see the wide world with his own eyes. Determined, the ronin set out on a rowboat journey and tours the world. He can cut anything down in half with his blade, and wants to test himself by seeing how far he can go with only one sword.
- (In English sources his story is slightly different, being similar to his anime story)
In his ending, "The Vast World", Ryoma breaks the Power Stone, saying that he doesn't need it. The universe is vast and infinite, and the thought of what lies ahead is invigorating, and embarks on a new adventure.
In Power Stone 2, Ryoma finally managed to obtain a legendary sword, "Tosa Arashi" (土佐嵐). He enjoys the moonlight reflecting on its edge, which cuts through iron like tofu. Suddenly, a strange light bounces off the sword's edge and shines on the huge shadow of a floating castle that appeared between the clouds. Ryoma's body flies up in the air. "Is this sword... guiding me to evil? Anyway, this is a good chance to give it a try." Ryoma goes up to the castle guided by the light of the sword. "Whatever enemy is waiting, I'll slice it up with this!"
His katana gives his attacks a long reach, but large swings and movements leave him open and vulnerable. With a sword in hand, he can have a tough time picking up and throwing objects. In the anime he is seen to be able to fight with two swords.
Ryoma's Power Change is a beetle-like silver samurai with electric powers.

Ryoma is a samurai from Moon Land that soon ran out of worthy opponents who could compete with his skill and test his might. His master gives him a Power Stone and tells him to travel the world to improve his skills, specially to challenge someone with a Power Stone. When he discovers that Edward Falcon has one, he challenges him for a duel. Although Ryoma has a Power Stone, he doesn't like to transform, prefering to fight with his own abilities due to his pride as a swordsman. He has a crush on Rouge.
