Ryouma Kurogane

""Are you frustrated to the fact that you are the weakest one? If so, hold on to that feeling. That's proof that you haven't given up yet, on yourself. Listen, don't give up saying that you're living within your boundaries. Don't be a boring person like that. If you have the guts to not give up, you can become anything you want to be. We're living creatures that don't have wings, but still went to the moon.""

- - Ryoma Kurogane

Ryoma Kurogane was widely known as Samurai Ryoma and a Legendary Blazer who led Japan to victory in the Second World War. He is also the great-grandfather of Ouma, Ikki, and Shizuku Kurogane.

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 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. His ideologies greatly differed from the strict guidelines of the Kurogane Family.

History
A legendary Blazer, a legendary samurai, and a war veteran, whose name is well known throughout the world, he led Japan to victory in World War 2. Ryoma had a long time rival named Torajirou Nangou. Ryoma was the Head of the Kurogane Family until he was overthrown by his own son Genma Kurogane and the elders, who disapproved of Ryoma's differing ideologies. Ryoma was half-exiled from the family. Ryoma is also mentioned having spectated the Seven Stars Sword Art Festival final between Kurono Shinguuji and Nene Saikyo. 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.
