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.""

- - Ryouma Kurogane

Ryouma Kurogane was renown as Samurai Ryouma and the Great Hero is a Legendary Blazer who led Japan to victory in World War II. He is both the father of Genma Kurogane and the grandfather of Itsuki Kurogane, as well as the great-grandfather of Ouma, Ikki, and Shizuku Kurogane.

Appearance
Ryouma 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, Ryouma 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 Ryouma 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
Ryouma Kurogane is a legendary Blazer and Samurai whose name became well-known all across the world as he led Japan to victory in the Second World War where he fought alongside both his friend and longtime rival, Nangou Torajirou. At some point, in the war, he also encountered Tendou Harima. Ryouma was the Head of the Kurogane Family until being overthrown by his own son Genma Kurogane and the elders, who disapproved of his ideologies resulting in him being half-exiled.

Ryouma is also mentioned having spectated the Seven Stars Sword Art Festival final between Kurono Shinguuji and Nene Saikyo. It is also implied that Ryouma taught the young Edelweiss in swordsmanship, although this is not confirmed. When Ikki was a child, Ryouma appeared before him, encouraging his great-grandson who was never given an opportunity to believe in himself and never give up. A few months after his encounter with his great-grandson, Ryouma dies of old age.

Abilities
Master Swordsmanship: Ryouma was mentioned as being an extremely skilled swordsman, even among the highly recognized Kurogane Family. He likely used the Kyokujitsu Isshin-ryuu swordsmanship, a style used by the members of the Kurogane Family.

Device
Unnamed Sword: Ryouma's Device, which was implied to be a sword.

Trivia

 * It is a common theory, that Ryouma is Tyrant, the leader of Rebellion, as they share several similarities. Both are strong characters who've been around for a long time since World War II and harbor at least some good intentions. Kouzou Kazamatsuri, one of the Numbers of Rebellion, also seemed to be affiliated with Ryouma in some way as he apologized to him. Though there are some doubts since if he were the Tyrant, then why would he beat up his great-grandson and why didn't Ouma know him aside from his overwhelming strength.
 * It's implied that Ryouma had taught Edelweiss in swordsmanship since her master is mentioned being an old Japanese man, as well as her saving his eldest great-grandson and attempts to save his two younger great-grandchildren instead of fighting them, then tried to get Ikki to stop his sister in the middle of their battle.
