Ryouma Kurogane

Ryoma Kurogane widely known as Samurai Ryoma is a legendary Blazer and Ikki's great-grandfather.

Appearance
Ryoma in his youth was a very strong man, who was only seen wearing his leg length jet black hair, in a ponytail. He was also only seen wearing an old age kimono, carrying a blade along with him.

In his elder days Ryoma is seen with long back length white hair, as well as a white beard, and mustache combo. He is also only seen wearing a Kimono, albeit without the colored jacket though, as well as the sword.

Personality
It seems as though Ryoma was a courageous and brave man, as he was once a legendary Blazer, who courageously participated, and almost led Japan to victory, in World War 2. He also seems kind as he, not caring about what his other family members thought of his great-grandson, encouraged Ikki to continue the path of becoming a Mage-Knight.

History
A legendary Blazer, a legendary samurai, and a war veteran, whose name is well known throughout the world, he almost led Japan to victory in World War 2. Ryoma had a long time rival named Torajirou Nangou.

It is implied that Ryoma taught the young Edelweiss in swordsmanship, although this is not confirmed.

When Ikki was a child, Ryoma appears before him, encouraging the boy who was never given an opportunity to believe in himself and never give up. A few months after his encounter with his great-grandson, Ryoma dies of old age.

Device
Unnamed Sword: Ryoma was seen carrying a sword. It's not confirmed though if this really was his Device.
