shinjuro rengoku

Shinjuro strongly resembles his sons, Kyojuro Rengoku and Senjuro Rengoku, possessing unruly orange hair that flares out around his face, becoming redder near the ends above his ears, that he wears messily tied back behind his head. He has fair skin, bushy black eyebrows and bright, orange eyes that redden near the pupils, that are slanted inwards and shaped so as to give him a furious appearance.

Shinjuro wears a traditional kimono robe. When he was the Flame Hashira, he also wore the haori with flame-like ridges at the end that Kyojuro wore when he was the Flame Hashira. In the Infinity Castle Arc, he is shown with a katana with a flame guard similar to Kyojuro's, with what appears to be a flame pattern on the sheath. is a very short-tempered man, especially when regarding the Demon Slayer Corps and his son, Kyojuro, with the mention of either causing him to grow furious. He appears to be abusive, harshly insulting the recently deceased Kyojuro and knocking Senjuro to the ground during his fight with Tanjiro. He is also an alcoholic - his first action upon awaking after being knocked out by Tanjiro is to buy alcohol, and he is often seen drinking with sake.

Shinjuro possesses feelings of inferiority, which stemmed from reading the chronicles of the past Flame Hashira, where Sun Breathing is described as the original and most powerful breathing style. He mocked the other styles as "cheap imitations" of Sun Breathing and accused Tanjiro of coming to their residence to mock them for his superiority, after recognizing his Hanafuda earrings.

However, it is later revealed that Shinjuro truly cared for Kyojuro despite what he said to Tanjiro, and the memory of Kyojuro causes Shinjuro to begin breaking down in tears.

He later defends Kiriya and the rest of the Ubuyashiki Family with Tengen Uzui and vows to follow Kyojuro's example and not to bring shame to the Rengoku family.

Senjuro has a similar appearance to his brother, Kyojuro Rengoku, and father, Shinjuro Rengoku, possessing unruly golden hair that flares out around his face, becoming red near the ends above his ears and shoulders, that he wears messily tied back behind his head. He has fair skin and large, gold eyes that redden near the pupils, that are slanted inwards and shaped so as to give him a determined yet kind appearance.

Senjuro wears a plain white yukata and juban with darker umanori-styled hakama pants. In Kyojuro Rengoku's memory dream in the Mugen Train, he wore a dark haori above his white yukata.Senjuro is originally seen to be very sad and rattled by his brother's death and his father's verbal abuse, but, after spending some time talking to Tanjiro Kamado, his true personality as a kind, caring individual who can usually see the best in a situation or person shines through. He has hope for his future, and even though he knows that by not becoming a Demon Slayer he has broken his family's ancient tradition, he knows that his older brother, Kyojuro, would forgive him for leaving such a scar on their history
