Kyojuro Rengoku and the demon Senjuro

Rengoku Kyojuro - A man holding the title of Flame Pillar in the Demon Slayer Corps, displaying incredible strength, an indomitable will, and genuine nobility. Kyojuro was distinguished by his extreme optimism, loud voice, and eccentric behavior. He firmly believed in the duty of the strong to protect the weak, a belief taught to him by his late mother. A tall man with golden-red hair reminiscent of flames, thick, forked eyebrows, and constantly wide eyes, he wore a white cloak with a fiery pattern. He was a master of the Breath of Flame. He taught himself most of his techniques from old textbooks, as his father, the former Pillar Shinjuro Rengoku, had become depressed and abandoned his son's training. He has a younger brother, Shojuro, and feels a strong sense of protection for him.

Kyojuro was given a mission on Mount Natagumo, because according to those around him, "A family of spiders lives there!" Kyojuro wasn't afraid and went on the mission. He had to work hard, because someone was using strings to control the other fighters and forcing them to fight Kyojuro. Kyojuro managed to save everyone, including those who had been turned into spiders by the poison. Kyojuro rushed resolutely through the forest and saw a silhouette sitting on a rock. "Time to deal with the demon!" "Hah?!" The strings grabbed Kyojuro and threw him toward the silhouette, still holding him.

"Krfgh! It was true what they told me, that the demons here are nimble! -.... Syonjuro?..."

Shojuro sat on a rock, and strings came from his fingers, which Shojuro used to control those he captured, including Kyojuro.
